A sphere at temperature `600 K` is placed in an enviroment to temperature is `200 K`. Its cooling rate is `H`. If its temperature reduced to `400 K` then cooling rate in same enviorment will become

A sphere at temperature 600 K is placed in an enviroment to temperature is 200 K . Its cooling rate is R . If its temperature reduced to 400 K then cooling rate in same enviorment will become

Si and Cu are cooled to a temperature of 300 K , then resistivity

Si and Cu are cooled to a temperature of 300 K , then resistivity

Intial temperature of a gas is 300 K & its gamma = 1.5 if adibatically its temperature reduced to 100 K, what will be effect on its volume & pressure.

The rate of cooling at 600 K, if surrounding temperature is 300 K is R. The rate of cooling at 900 K is

An engine runs between a reservoir at temperature 200 K and a hot body which is initially at temperature of 600 K. If the hot body cools down to a temperature of 400 K in the process, then the maximum amount of work that the engine can do (while working in a cycle) is (the heat capacity of the hot body is 1 J/K)
