If for hydrogen $$ C_{p}-C_{v}=m $$ and for nitrogen $$ C_{p}-C_{v}= $$ $$ n, $$ where $$ C_{p} $$ and $$ C_{v} $$ refer to specific heats per unit mass respectively at constant pressure and constant volume, the relation between $$ m $$ and $$ n $$ is (molecular weight of hydrogen $$ =2 $$ and molecular weight of nitrogen $$ =14 $$ )

An immersion heater, in an insulated vessel of negligible heat capacity, brings 100 g of water to the boiling point from $$16^{0}C$$ in 7 min. Then

         The heat of vaporization of alcohol is

Three rods of identical cross-sectional area and made from the same metal form the sides of an isosceles triangle ABC right angles at B. The points A and B are maintained at temperatures T and $$\sqrt{2}T$$, respectively, in the steady state. Assuming that only heat conduction takes place, temperature of point C

A marble tile would feel cold as compared to a wooden tile on a winter morning, because the marble tile
