A substance of mass m kg requires a power input of P watts to remain in the molten state at its melting point. When the power is turned off, the sample completely solidifies in time t s. What is the latent heat of fusion of the substance?

The quantity of heat required to convert unit mass of a substance from its solid state to the liquid state, at its melting point without change in its temperature is called as

A substance is in the solid form at 0^@ C. The amount of heat added to this substance and its temperature are plotted in the following graph. If the relative specific heat capacity of the solid substance is 0.5, find from the graph (i) the mass of the substance, (ii) the specific latent heat of the melting process and (ii) the specific heat of the substance in the liquid state. Specific heat capacity of water =1000 cal//kg//K

One end of a uniform rod of length 1m is placed in boilling water while its other end is placed in boiling water while its other end is placed in melting ice A point P on the rod is maintained at a constant temperature of 800^(@)C mass of stam produced per second is equal to the mass of ice melted per second. is equal to mass of ice melted per second If specific latent heat of steam is 7 times the specific latent heat of ice, then the distance of P from the steam chamber is n//18 m Find the value of n ? .
