One end of a copper rod of uniform cross-section and of length 3.1 m is kept in contact with ice and the other end with water at 100° C . At what point along it's length should a temperature of 200° C be maintained so that in steady state, the mass of ice melting be equal to that of the steam produced in the same interval of time. Assume that the whole system is insulated from the surroundings. Latent heat of fusion of ice and vaporisation of water are 80 cal/gm and 540 cal/gm respectively

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 ? .

One end of a uniform rod of length 10m 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 450^@C . The mass of steam produced per second is equal to the mass of ice melted per second. If specific latent heat of steam is 7 times the specific latent heat of ice, the distance of P from the steam chamber must be___________(in m)

One mole of a uniform rod of length 1 m 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 . The mass of steam produced per second. Is equal to the mass of ice melted per second. If specific latent heat of steam is 7 times the specific latent heat of ice, then distance of P from the steam chamber is n//18 m . Find the value if n ?

Two bodies of equal mass m are heated at a uniform rate under identical condition. Their change in temperature are shown. Then (i) The ratio of melting point of the substances is 1.5 (ii) the ratio of their latent heats is 0.75 (iii) the ratio of specific heat of two substances is 0.33 in solid state (iv) the ratio of specific heat of two substances is 2 in liquid state.
