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 26.8 25 34.4 40.5 26.8 25 34.4 40.5 ANSWER DOWNLOAD EXAMIANS APP
