The temperature of the copper sample increases by
Explanation:
When energy is supplied to a substance, the temperature of the substance increases according to the equation:
where
is the increase in temperature
Q is the amount of energy supplied
m is the mass of the substance
is the specific heat capacity of the substance
For the sample of copper in this problem,
m = 538.0 g
Q = 8373 cal
Therefore, substituting we have:

Apply Gay-Lussac's law:
P/T = const.
P = pressure, T = temperature, the quotient of P/T must stay constant.
Initial P and T values:
P = 180kPa, T = -8.0°C = 265.15K
Final P and T values:
P = 245kPa, T = ?
Set the initial and final P/T values equal to each other and solve for the final T:
180/265.15 = 245/T
T = 361K
