1 North arolina Testing Program EO hemistry Sample Items Goal 4 1. onsider the spectrum for the hydrogen atom. In which situation will light be produced? 3. Which color of light would a hydrogen atom emit when an electron changes from the n = 5 level to the n = 2 level? Electrons absorb energy as they move to an excited state. Electrons release energy as they move to an excited state. red yellow green Electrons absorb energy as they return to the ground state. blue Electrons release energy as they return to the ground state. 2. Which statement regarding red and green visible light is correct? 4. What energy level transition is indicated when the light emitted by a hydrogen atom has a wavelength of 103 nm? n = 2 to n = 1 The speed of green light is greater than that of red light. The wavelength of green light is longer than that of red light. The energy of green light is lower than that of red light. The frequency of green light is higher than that of red light. n = 3 to n = 1 n = 4 to n = 2 n = 5 to n = 2 Page 1

The gases helium, neon, and argon are in separate containers at 55. Which is true about the kinetic energy of the gases? Which statement best describes the effect of the temperature changes on the kinetic energy of the particles? Kinetic energy of metal atoms decreases in the flame. Helium has the lowest mass and therefore greatest kinetic energy. They each have a different kinetic energy. rgon has the greatest mass and therefore the greatest kinetic energy. They all have the same average kinetic energy. Kinetic energy of water molecules increases when the heated metal is immersed. 7. This is a heating curve for a substance. Kinetic energy of water molecules decreases when the heated metal is immersed. Kinetic energy of metal atoms increases when immersed in the cooler water.
