If 80 g steam of temperature `97^(@)C` is released on an ice slab of temperature `0^(@)C` ,how much ice will melt ? How much energy will be transferred to the ice when the steam will be transformed to water?
0.014 kg of ntirogen is enclosed in a vessel at a temperature of 27^(@)C . How much heat has to be transferred to double the rms speed of its molecules.
A thermally insulated pot has 150 g ice at temperature 0^(@)C . How much steam of 100^(@)C has to be mixed to it, so that water of temperature 50^(@)C will be obtained ?
Answer these (a) How much energy is transferred when 1 g. of boiling water at 100^@ C condenses to water at 100^@ C ? (b) How much energy is transferred when 1 g. of boiling water 100^@C cools to water at 0^@ C? (c) How much energy is released or absorbed when 1 g. of water at 0^@ C freezes to ice at 0^@ C ? (d) How much energy released or absorbed when 1 g. of steam at 100^@ C cools to ice at 0^@ C?
0.1 m^(3) of water at 80^(@)C is mixed with 0.3 m^(3) of water at 60^(@)C . What is the final temperature of the mixture ?
How much heat energy is required to melt 5 kg of ice? (Specific latent heat of ice = 336 Jg^(-1) )
A piece of ice of mass of 100g and at temperature 0^(@)C is put in 200g of water of 25^(@) How much ice will melt as the temperature of the water reaches 0^(@)C ? The specific heat capacity of water = 4200 J kg ^(-1)K^(-1) and the latent heat of ice = 3.36 xx 10^(5)J kg^(-1)
One mode of an ideal monatomic gas is kept in a rigid vessel. The vessel is kept inside a steam chamber whose temperature is 97^(@)C . Initially, the temperature of the gas is 5.0^(@)C . The walls of the vessel have an inner surface of area 800cm^(2) and thickness 1.0cm If the temperature of the gas increases to 9.0^(@)C in 5.0 second, find the thermal conductivity of the material of the walls.
