A solid object of mass M is made from a material of specific heat capacity C and specific latent heat of fusion L and of very high thermal conductivity enters the atmosphere from
outer space, its temperature being below its melting point by !:!T. Because of atmospheric friction it absorbs energy at a constant rate R. The time before the solid becomes
completely molten is given by:
