the specific heat capacity of liquid in terms of above data.
How will you prove experimentally that different substances have different specific heat capacities?
Water boils at 120 °C in a pressure cooker. Explain the reason.
Write an expression for the heat energy liberated by a hot body.
A. hot solid of mass 60 g at 100°C is placed in 150 g of water at 20° C. The final steady temperature recorded is 25°C. Calculate the specific heat capacity of the solid. [Specific heat capacity of water = 4200 J kg-1 °C-1]
Express the change in internal energy in terms of molar specific heat capacity.
The value of 'γ' for a gas is given as `gamma = 1 + 2/"f"`, where 'f ' is the number of degrees of freedom of freedom of a molecule of a gas. What is the ratio of `gamma_"monoatonic"//gamma_"diatomic"`?
Diatomic gas consists of rigid gas molecules
