An insulated cylinder fitted with a movable piston to maintain constant pressure initially contains 100 g of ice at -10 C. Heat is supplied to the contents at a constant rate by a 100 W heater. Make a graph showing temperature of the cylinder contents as a function of time starting at t = 0, when the temperature is -10 C and ending when the temperature is 110 C. Let c = 2.0 kJ/kg Kfor specific heat of ice from -10 to 0 C and of the steam from 100 to 110 C. The specific heat of water between 0 C and 100 C is c = 4.18 X 103 J/kg K. The value of Lv = 2257 X 103 J/ kg and Lf = 333.5 X 103 J/kg.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
