200 g mass of certain metal of 83°C is immersed in 300 g of water at 30°C the final temperature
is 33°C. Calculate the specific heat capacity of the metal Assume that the specific heat capacity
of water is `4.2 J g^-1K^-1`
Describe an experiment to show that there is absorption of heat energy when the ice melts.
A block of lead of mass 250 g, at 27°C was heated in a furnace till it completely melted. Find the quantity of heat required
(a) To bring the lead block upto its melting point,
(b) To completely melt the block at its melting point (Melting point of lead is 327°C, Sp. heat cap. of lead is 0.13 J/gk and latent heat of fusion of lead is 26 J/g)
100 g of ice at -10°C is heated. It is converted into steam. Calculate the quantity of heat which it has consumed. (Sp. heat of ice = 2100J/kg°C, sp. heat of water= 4200 J/kgK, sp. heat of water = 42000 J/kgK, sp. latent heat of ice = 2260000 J/kg).
