# Need some help with heat homework

A 1.0kg sample of metal with a specific heat of 0.50 KJ/KgC is heated to 100.0C and then placed in a 50.0g sample of water at 20.0C. What is the final temperature of the metal and the water?

Heat energy=mass*(Final temp.-initial temp.)*Specific Heat

i have no idea how to even start

Let the initial temp. of the metal be $\theta$

Assuming no heat losses,all the heat from the metal goes into increasing the temperature of the water.

Heat energy=mass*(Final temp.-initial temp.)*Specific Heat

Find the heat energy the metal has when it's final temperature is 100 and initial is $\theta$.

For the water, the initial temperature is 20. Can you find a similar expression for heat energy?
