Question

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

A. 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.
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 different 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 different temperatures, and measure the temperature of the water.

Answer 1

To best determine which metal cube transfers the most heat to water, Sandra should heat each cube to the same temperature, place them into separate containers with 500 grams of water at the same temperature, and measure the temperature changes of the water.

Step-by-step explanation:

To determine which metal cube transfers the most heat to 500 grams of water, Sandra should use the following procedure:

• Heat each cube to the same temperature.
• Place each cube into separate containers with 500 grams of water, ensuring that the water in each container is at the same temperature before cube insertion.
• Measure the temperature of the water after a set amount of time has passed, which will show how much each metal cube has raised the water's temperature.

This method will allow Sandra to compare the heat transfer capabilities of each metal effectively. Notably, option A from the question provides a description that aligns with these steps.
