True Cooling a substance causes its molecules to slow down and get slightly closer together, occupying a smaller that results in an increase in density. volume

6 Short Answer What is the mathematical equation for density? Density = mass/volume or D=m/v Density is measured in g/cm 3. Think about the formula Density = mass/volume and explain why density is measured in g/cm 3. Mass is measured in grams, and volume is measured in cm 3. If two substances have the same volume, but the first one has greater mass, which one will have the greater density? The first one because if density = m/v, and the first one has more mass, this would make the density greater. Imagine that you have a cube of copper and a cube of aluminum which are exactly the same size and shape. When you place them each on an electronic balance, you find that the copper cube has more mass than the aluminum cube. Give one possible reason why the copper cube has more mass. Copper atoms each have a greater atomic mass than aluminum atoms. or Copper atoms are smaller so that more of them can fit in a cube. or Copper atoms are arranged closer together so that there are more atoms in the cube. Glass jars are much more dense than plastic jars. What can you guess about the mass, size, and arrangement of the molecules that make up glass compared to the molecules that make up plastics? Glass could have smaller more massive atoms that are close together which would give glass a higher density. In addition to their arrangement, what are two other properties of atoms that can affect density? The size of the atoms and their mass can also affect density.

7 Pretend that you have two substances. Substance A is made up entirely of one kind of atom. Substance B is made up entirely of another kind of atom. If the atoms that make up substance B are smaller and less massive than the atoms that make up substance A, is it possible for substance B to have a greater density? Why? Yes it is possible. Even though they are less massive, if they are small enough, there may be so many atoms in a volume of substance B that the overall mass compared to the volume is actually greater than substance A. How can you use the displacement method to find the volume of a sample? First you put water in a graduated cylinder and check the initial volume. Then you place the sample all the way into the water and see the final level where the water is. Then you subtract the initial volume from the final volume. This will give you the volume of the sample. What is the volume of an object that made the water level rise in a graduated cylinder from 50 ml to 59 ml? Remember that volume is measured in cm 3 and not ml when giving your answer. The volume of the object would be 9 cm 3. When using the water displacement method, you were instructed to push the cylinder that floated down so that it was just beneath the surface of the water. What would you measure if you let the cylinder float when you looked at the water level in the graduated cylinder? If you left the object floating, you would find the volume of only of the part that was under water. Because you want the volume of the entire cylinder, you have to make sure that the entire cylinder, and nothing else, goes under water. Will different volumes of water always have the same density? Why or why not? They should if their temperatures are the same. The amount of water doesn t matter but the temperature does. How can you use a graduated cylinder, water, and an electronic balance to find the density of water? I would use a graduated cylinder to measure a certain amount of water in ml. Then I would use the balance to measure the mass of this amount of water in grams. Because 1 ml is the same as 1 cm 3, the density is the number of grams divided by the number of ml of water. What is the density of water? The density of water is 1 g/cm 3. What does it mean that density is a characteristic property of a substance? This means that any sample of the substance should have the same density. It doesn t matter whether it is a large or small sample. They should all have the same density.

8 How can you use density to identify an unknown substance? If you know the density of different substances, you can calculate the density of the unknown substance and see if it is similar to the density of one of the known substances. Look at the graph to help you answer the question. What would you expect the mass of 500 ml of water to be? Why? Looking at the chart, the volume of water in ml is always the same as the mass of water in grams. So the mass of 500 ml of water will be 500 g. Explain, on the molecular level, why a candle floats in water. A candle floats because it is less dense than water. It is less dense because the molecules that make up wax are made from atoms which are a little bit less massive than the atoms that make up water and they are not packed as tightly together as water molecules. Look at the drawings below and think about the size, mass, or arrangement of water molecules compared to the molecules of wax. Why does a candle float on water? Water molecules and wax molecules both have hydrogen but water has oxygen and wax has carbon. Oxygen is a little smaller than carbon and also heavier. Water molecules are also packed closer together than the molecules of wax. All this makes water more dense than wax.

9 A piece of ice floats on water. What does this tell you about the density of ice compared to the density of water? Ice is less dense than water. A solid piece of candle wax sinks in melted wax. What does this tell you about the density of a solid piece of candle compared to the density of melted wax? A solid piece of candle wax is more dense than melted wax. Will an object with a density of 0.86 g/cm 3 sink or float in water? How do you know? It will float because its density is less than the density of water, which is 1 g/cm 3. How does dissolving salt in water change the density of the water? Dissolving salt in water adds mass to the water but does not increase the volume very much. Since D=m/v, if mass increases more than volume, the density will increase. How would you expect water, isopropyl alcohol, and saltwater to layer if you poured them into a cup? Top: Isopropyl alcohol Middle: Water Bottom: Saltwater How could you use a graduated cylinder and balance to find out which is more dense, saltwater or isopropyl alcohol? I would measure 20 ml of each solution in a graduated cylinder. Then I would place each graduated cylinder on a balance. The one that has more mass is the most dense. Explain, on the molecular level, how hot water can float on room-temperature water. In hot water, the water molecules move faster and get a little further apart. Therefore, the same mass of water has a slightly larger volume. Since D=m/v, a larger volume means a lower density. Therefore hot water is less dense than room temperature water and can float on it. Briefly explain how cooling water affects its density. Cooling water causes the molecules to slow down and their attractions to bring them closer together. This makes the same mass of water take up slightly less volume. Since D=m/v, a smaller volume means a higher density. Therefore cold water is more dense than room temperature water and will sink in it. This is true until water begins to freeze. When it freezes, water molecules move further apart than in liquid water. This makes ice less dense than water causing it to float.

10 You put cold water colored blue into room temperature water. The cold water sank in the room temperature water. Use what you know about the motion and attraction of molecules and density to explain why this happened. Since the water was colder, the water molecules were moving slower so their attractions brought them closer together. Since the molecules were closer together, there is more mass per volume of water. This makes the water more dense than room temperature water so the cold water sinks. It might seem strange but hot water and ice both float on room temperature water. Explain why this happens. In hot water, the molecules move faster. This motion competes with their attractions and they move a little further apart. This means that there is less mass per volume of water. This makes the water less dense than room temperature water so the hot water floats. In ice, the water molecules are actually further apart than they are in room temperature water. This makes ice less dense than water so ice floats. Refer to the diagram below to explain why hot water will float on cold water? The molecules in hot water are slightly further apart than in cold water. This increases the volume slightly while the mass stays the same. This makes hot water less dense, so it floats on the more dense cold water.
