Correct answer
D. Tempering
Explanation
The correct answer is Tempering.
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________?
Extensive properties of a thermodynamic system depend upon the ________ of the system?
Cellulose content of bamboo and ideal fibrous raw material for the manufacture of paper is ________ percent?
Filtration capacity of a rotary drum vacuum filter depends upon the________?
Trinitro-toluene (TNT) is ________?
For turbine agitator, the impeller diameter is about________?
