When the temperature of an ideal gas is increased from 27$$^\circ$$C to 127$$^\circ$$C. Calculate the percentage increase in its $$v_{rms}$$.

Boiling water is changing into steam. The specific heat of boiling water is

If the volume of a block of metal changes by $$0.12 \%$$ when heated through $$20^{\circ} \mathrm{C}$$, then find its coefficient of linear expansion.

Isothermal process is the graph between
