How much heat is released when a 260.0 g plate of copper tools from 5.30 x 10^2K to 20.0C? 

Expert Answer

Step 1

The specific heat capacity for a given chemical substance or a solution refers to the amount of the heat that is required to increase the temperature of a given substance or system per unit of its mass. The mathematical relationship between specific heat capacity, mass, change in temperature and the heat of the solution is given by the following equation:

q=mxcxAT q is the amount of heat or energy released or absorbed during the reaction m is the mass of the given substance c is the specific heat capacity AT is the change in the temperature of the system

Step 2

The initial temperature is given to be 5.30×102K=530 K= 256.85 oC.

The final temperature is given to be 20oC.

The mass of Copper plate is given to be 260.0 g.
