" The specific heat capacity of water is: "

A scientist proposes a new temperature scale in which the ice point is 25 X(X is the new unit of ternperature) and the steam point is 305 X. The specific heat capacity of water in this new scale is (in Jkg^(-1)X^(-1) )

Show that the specific heat capacity of water in terms of universal gas constant.

What is the specific heat capacity of water in different system of units?

Give one example where high specific heat capacity of water is used as a heat reservoir.

Give one example each where high specific heat capacity of water is used (i) as coolant, (ii) as heat reservoir.

Give one example where high specific heat capacity of water is used for cooling purposes.

If 5 L of water at 50^(@)C is mixed with 4L of water at 30^(@)C , what will be the final temperature of water? Take the specific heat capacity of water as 4184 J kg^(-1) K^(-1)
