Applied ScienceHeat and Temperature BTEC NationalEdexcel Created by: Saarah17Created on: 03-11-22 18:29 What will happen when 2 identical objects of temperatures 0°C and 100°C come into contact? Heat transfer will occur until equilibrium 1 of 7 What will happen when 2 identical objects of 50°C come into contact? No heat energy is transferred between them 2 of 7 2 objects in contact are at the same temperature No heat energy transferred between them. Said to be in thermal equilibrium. 3 of 7 Quantity of thermal energy Heat which is transferred during a process 4 of 7 Calculating Efficiencies Efficiency = W(out) / W(in) 5 of 7 W(out) Output Work/Energy (Work / Energy generated by the system) 6 of 7 W(in) Input Work/Energy (Work / Energy supplied to the system) 7 of 7
