A10-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

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.
