#CP = T_h/(T_h - T_c) = (523K)/(523K - 373K) = 3.487#

#CP = Q_h/W; \qquad \rightarrow Q_h = CP\timesW=1743J#

Explanation:

#T_h = 250^oC = 523K; \qquad T_c = 100^oC = 373K;#
#W = 500J; \qquad Q_h = ?#

Coefficient of Perfromance: #\quad CP \equiv Q_h/W = T_h/(T_h-T_c)#

#CP = T_h/(T_h - T_c) = (523K)/(523K - 373K) = 3.487#

#CP = Q_h/W; \qquad \rightarrow Q_h = CP\timesW=1743J#
