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