At which temperature specific heat of water is minimum ?

A radio nuclide with disintegration constant lambda is produced in a reactor at a constant rate alpha nuclei per second. During each decay energy E_0 is released. 20% of this energy is utilized in increasing the temperature of water. Find the increase in temperature of m mass of water in time t . Specific heat of water is s . Assume that there is no loss of energy through water surface.

How do you appreciate the role of the higher specific heat of water in stabilizing atmospheric temperature during winter and summer seasons?

100g of water is heated from 30^@C to 50^@C . Ignoring the slight expansion of the water, the change in its internal energy is (specific heat of water is 4184J//kg//K ):

By increasing the temperature, the specific resistance of a conductor and a semiconductor.

Write the value of specific heat capacity of water with unit.

What is specific heat ? Give its unit and on which factors does specific heat depends upon ?

Define specific heat capacity, write its unit.

A quantity of 2 mole of helium gas undergoes a thermodynamic process, in which molar specific heat capacity of the gas depends on absolute temperature T , according to relation: C=(3RT)/(4T_(0) where T_(0) is initial temperature of gas. It is observed that when temperature is increased. volume of gas first decrease then increase. The total work done on the gas until it reaches minimum volume is :-

A calorimeter of heat capacity 100 J//K is at room temperature of 30^(@)C . 100g of water at 40^(@)C of specific heat 4200 J//kg-K is poured into the calorimeter. What is the temperature of water is calorimeter?
