I'm lost....

"The specific heat capacity of copper is 0.092 calories per gram per degree Celsius. How much heat is required to raise the temperature of a 10-gm piece of copper from 0 degrees celsius to 100 degrees celsius? How does this compare with the heat needed to raise the temperature of the same mass of water through the same temperature difference?

are you kidding me? the answer is more or less contained in the question.

1) this is not a physics problem, it's a chem problem.

2) the specific heat is given in c/g(deg). to cancel out deg and g simply multiply the specific heat by the mass you're trying to heat (10) and the change in temperature (100).

3) to compare that answer to water, just google the value for the specific heat of water. do the same thing i just told you to do (multiply by mass and change in temperature). tada, you just did your homework all by yourself.

If needed, you can convert your answer from calories to joules as well, depending on what your teacher is looking for.

Edit: Holy beans abdullah, let a kid do their own homework!!!

This formula allows you to calculate temperature changes when a given system absorbs or releases a certain amount of heat:
Q = c*m*dT

Q = (0.092)(.010)(100)

Q = .092 J

Here's the second part of the question:

Q = c*m*dT

Q = (4184)(.010)(100)

Q = 4184 J

The amount of heat required to change the temperature of 10g of water from 0 to 100 degrees (celsius) is 4183.9 J more than the amount of heat required to change the temperature of 10g of copper from 0 to 100 degrees.
