A student is heating a substance in a test tube. After putting the test tube in a rack, the student realizes that the test tube clamp is warm. The student dips the test tube clamp in a pan of water to cool it. Which statement correctly describes the heat transfer that occurs when the test tube clamp is placed in the water? Heat vaporizes from the clamp faster in water than in air. Heat is transferred from the clamp in the form of convection currents. Water conducts heat energy from the clamp, which lowers its temperature. Water makes the clamp radiate more heat, which then lowers its temperature.
