For a certain engineering application, it is required to rise the temperature of a given mass of a body as quickly as possible. The material should have

If the heat required to raise the temperature of a body of mass m through t^0C is H. then the specific heat of the substance of the body is

With rise in temperature, density of a given body changes according to one of the following relations

At constant pressure certain quantity of water at 24^(@)C is heated. It was observed that the rise of temperature was found to be 4^(@)C per minute. Calculate the time required to rise the temperature of water to 100^(@)C at sea level by using formula.

For a body of mass m and specific heat capacity s, how much heat is required to increase its temperature by t?

By what percentage should the pressure of a given mass of a gas be increased so as to decrease its volume by 10% at a constant temperature?

By what percentage should the pressure of a given mass of a gas be increased so as to decrease its volume by 20% at a constant temperature?
