Question

A 10-gram sample of water will lose the greatest amount of heat when its temperature is changed from 50°C to

1. 10°C
2. 20°C
3. 30°C
4. 40°C

Answer 1

I believe the correct answer from the choices listed above is option 1. A 10-gram sample of water will lose the greatest amount of heat when its temperature is changed from 50°C to 10°C. Heat is directly proportional to the change in temperature so the larger the temperature gradient the greatest amount of heat. Hope this helps.
