Question

A 150g potato cools from 100 degrees Celsius to 50 degrees Celsius. If the specific heat capacity of the potato is 2000 j/kg degrees Celsius, how much heat does the potato lose?

Answer 1

q = mass x specific heat x delta T = ?
If you use mass in grams, you must change specific heat to 2 J/g*C and q will be in J.

Answer 2

20 000 J

Answer 3

-15000000
