Need help with homework question. Anyone please thank you

In summary, the conversation is discussing how to solve two questions involving heat transfer. The first question involves determining how much heat a silver spoon absorbs from coffee to reach a specific temperature, while the second question involves calculating the heat removed by cooling tower water for each kilogram of spent steam. The solution involves using the specific heat of silver and a formula for heat and temperature change, which can be found in a physics textbook or through online research.

Homework Statement



a 50.0g silver spoon at 20.0*C is placed in a cup of coffee at 90.0*c. how much heat does the spoon absorb from the coffee to reach a temperature of 89.0*C

HOW DO I SOLVE THIS!

and also this question

Spent Steam from an electric generating plant leaves the turbines at 120.0*C and is cooled to 90.0*C liquid water by water from a cooling tower in a heat exchanger. how much heat is removed by the cooling tower water for each kilogram of spent steam?

You need the value of a physical constant known as the specific heat of that metal (silver). If it's not in your textbook, use google.

While the OP has seen the solution that was posted, I'll just remark that there should be a discussion of this topic in the OP's physics textbook, along with the formula relating heat and temperature change, plus a list of specific heat values for different materials.
