Question

Sandra has five cubes each made of a different metal. Each cube has a mass of 100 grams. Which procedure should Sandra use to best determine which metal cube transfers to most heat to 500 grams of water?

A.
Heat each cube to a different temperature, place each cube into different containers with 500 grams of water at different temperatures, and measure the temperature of the water.
B.
Heat each cube to a different temperature, place each cube into different containers with 500 grams of water at the same temperature, and measure the temperature of the water.
C.
Heat each cube to a the same temperature, place each cube into different containers with 500 grams of water at different temperatures, and measure the temperature of the water.
D.
Heat each cube to the same temperature, place each cube into different containers with 500 grams of water at the same temperature, and measure the temperature of the water.

Answer 1

Sandra should heat each metal cube to the same temperature, place them each in 500 grams of water at the same temperature, and then measure the temperature increase of the water to determine which cube transfers the most heat.

Step-by-step explanation:

To best determine which metal cube transfers the most heat to 500 grams of water, Sandra should follow the procedure: Heat each cube to the same temperature, place each cube into different containers with 500 grams of water at the same temperature, and measure the temperature of the water. This procedure will allow Sandra to control for variables and only evaluate the heat transfer properties of each metal. By keeping the initial temperatures of the cubes and the water consistent, Sandra can accurately compare the difference in temperature increases of the water to ascertain which metal cube transfers the most heat.
