1 kg of ice occupies `1.1xx10^(-3) m^3` at N.T.P. The volume changes to `1xx10 ^(-3)m^3` , when it is melted. internal latent heat is(latent heat of fusion of ice = 80 k cal/kg P= 1.013xx10^5 N/m^2, J= 4200 J/k cal)

Calculate the amount of heat required to convert 10g of ice at - 10^@C to water at 5^@C (latent heat of fusion of ice = 80 cal g^(-1) , specific heat of ice = 0.5).

A metal rod 25 cm long and 10sq cm in cross section has it's one end placed in boiling water and the other end in melting ice. Calculate the mass of ice method per minute if K for metal is 378 W/mk. Latent heat of fusion of ice - 80 K cal/gm . J = 4200 j/Kcal.

Calculate r.m.s. speed of nitrogen at 0^@C ( Density of nitrogen = 1.25 kg/m^3 at N.T.P., 1 atmosphere = 1.013xx10^5 N/m^2 )
