Answer:

Explanation:
When a substance is supplied with a certain amount of heat energy, the temperature of the substance increases according to the equation

where
m is the mass of the substance
Q is the amount of energy supplied
C is the specific heat of the substance
is the temperature change
In this problem:
Q = 758 J is the energy supplied
m = 0.750 kg is the mass of the sample
is the specific heat of copper
Re-arranging the equation, we can find the increase in temperature:
