help! need help here because my answers are different from the answer on the book. just wanted to make sure that i am right. these are the problems:(adsbygoogle = window.adsbygoogle || []).push({});

1. How much heat is needed tor aise the temperature by 10 deg celsius of 5 kg og a substance of specific heat capacity 300J/kg deg celsius? what is the thermal capacity of the substance?

- i got the answer for the specific heat capacity but for thermal capacity my answer is 1500 J/deg celsius and the book's answer is 15000 J/deg celsius.

2. If a freezer cools 200 g of water from 20 deg celsius to its freezing point in 10 minutes, how much heat is removed per minute from the water?( this is under specific latent heat of fusion but i think i solved it using specific heat capacity)

- my answer is 1680 J/min but the book's answer is 1700 J/min.

please help me. thanks
