Answer:
[tex]2.6^{\circ}C[/tex]
Explanation:
When a certain amount of heat energy is supplied to a substance, the temperature of the substance increases according to:
[tex]Q=mC\Delta T[/tex]
where
Q is the amount of heat energy supplied
m is the mass of the substance
C is the specific heat capacity of the substance
[tex]\Delta T[/tex] is the change in temperature
In this problem:
Q = 758 J is the heat supplied
m = 0.750 kg is the mass
[tex]C=385kg/JC[/tex] is the specific heat of copper
Solving for [tex]\Delta T[/tex], we find the increase in temperature:
[tex]\Delta T=\frac{Q}{mC}=\frac{758}{(0.750)(385)}=2.6^{\circ}C[/tex]
