In an internal combustion engine, air at 1 atm and temperature of about 20°C is compressed by the piston to 19 of its original volume. (a) What is the temperature of the compressed air; if the pressure (absolute) increases to 40 atm. (b) An automobile cooling system holds 16 L of water. How much heat does its temperature rises from 20°C to 90°C ? [ 1 m3 = 1000 L ; Specific Heat of Water = 4186 J/kg °C ]
