Why a gas has two principal specific heat capacities?

Define specific heat.

Write short note on specific heat capacity.

Of what significance is the difference between these two specific heat capacities ratios?

For an ideal gas (C_(p,m))/(C_(v,m))=gamma . The molecular mass of the gas is M, its specific heat capacity at constant volume is :

Dimensional formula of specific heat capaicty is

What is S.I. unit of specific heat?

Explain how the high value of specific heat capacity of water helps in making the climate of the coastal regions moderate?

A fully charged capacitor has a capacitance 'C'. It is discharged through a small coil of resistance wire embedded in a thermally insulated block of specific heat capacity 's' and mass 'm'. If the temperature of the block is raised by DeltaT , the potential difference 'V' across the capacitance is
