An ice cube of dimensions is placed in an insulation box of wall thickness . The box keeping the ice cube at of temperature is brought to a room of temperature . The rate of melting of ice is approximately.
(Latent heat of fusion of ice is and thermal conducting of insulation wall is A black body radiates heat energy at the rate of at temp. of . The temp of black body at which rate becomes is: The amount of radiation emitted by a perfectly black body is proportional to Amount of heat required to raise the temperature of a body through 1K is called its If Poissonβs ratio is for a material, then the material is
