Heat Transfer One kilogram of water at 0°C is changed to superheated steam of one atm pressure and 300° C. The major heat consumption in the process will be to Heat the water from 0°C to 100°C Evaporate the water To superheat the steam Data insufficient, can Heat the water from 0°C to 100°C Evaporate the water To superheat the steam Data insufficient, can ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In Joule's experiment, an insulated container contains 20 kg of water initially at 25°C. It is stirred by an agitator, which is made to turn by a slowly falling body weighing 40 kg through a height of 4 m. The process is repeated 500 times. The acceleration due to gravity is 9.8 ms⁻². Neglecting the heat capacity of agitator, the temperature of water (in °C) is 25 34.4 40.5 26.8 25 34.4 40.5 26.8 ANSWER DOWNLOAD EXAMIANS APP
