Question #dd1a1 Physics Heat Temperature and Thermal Equilibrium 1 Answer Cosmic Defect Dec 9, 2017 #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# Answer link Related questions Question #25593 Question #84776 Question #25597 How do you convert Fahrenheit to Celsius?
