Question

farcher · Answer

Heat lost or gained = mass X specific heat capacity X temperature change

anonymous · Answer

so would it be 390x30,000x3.9 ?

farcher · Answer

No - the heat gained is put to the left of the equals sign.
Just put the numbers in the equation I wrote and then solve for the temperature change

anonymous · Answer

So its change in temperature = 30000 / (390 * 3.9)  which would be 19.72 degrees Celsius?
