Heat Energy Review

Kim knows that most things that create light also create heat. She wants to know how much heat is given off by the bulb on her desk lamp while she is doing her homework. Which of the following would be the best way for Kim to measure how much heat the bulb puts out?

• Place a glass of ice under the lamp to see whether it will melt.

• Place a black shirt under the lamp and feel how hot it gets.

• Place her hand under the lamp to see if her hand gets warm.

• Place a thermometer under the lamp and measure the temperature.
