Water is being boiled in a flat bottomed kettle placed on a stove The area of the bottom is `300cm^(2)` and the thickness is `2mm` If the amount pf steam produced is `1gm min^(-1)` then the difference of the temperature between the inner and the outer surface of the bottom is (thermal conductivity of the matrial of the kettle `0.5calcm^(-1)C^(-1)` latent heat of the steam is equal to `540calg^(-1))` .

Water is boiled in flat bottom kettle placed in a stove. The area of the bottom is 3000 cm^2 and the thickness is2 mm. If the amount of steam produced is 1 g min^(-1) . Then, the difference of temperature between inner and outer surfaces of the bottom is [K, for the material of kettle is 0.5 cal^0 C ^(-1) s^(-1) 1 cm ^(-1)]

Water is being boiled in flat bottom kettle placed on a stove. The area of the bottom is 3000cm^2 and the thickness is 2 mm. If the amount of steam produced is 1g//min , calculate the difference of temperature between the inner and outer surface of the bottom. K for the material of kettle is 0.5 cal^@C//s//cm , and the latent heat of steam is 540 cal//g .

A falt-bottom kettle placed on a stove is being used to boil water. The area of the bottom is 270cm^(2) the thickness is 0.3 cm and the thermal conductivity of the material is 0.5 "cal"//s cm^(@)C . If the amount of steam being produced in the kettle is at the rate of 10 g per minute calculate the difference of temperature between the inner and outer surfaces of the bottom. The latent heat of steam is 540 "cal"//gm .

Steam at 100^(@)C is passed into a copper cylinder 10 mm thick and of 200 cm^(2) area. Water at 100^(@)C collects at the rate of 150 g min^(-1) . Find the temperature of the outer surface, if the conductivity of copper is 0.8 cal s^(-1) cm^(-1) .^(@)C^(-1) and the latent heat of steam is 540 cal g^(-1) .
