Quantity of heat lost in condensation of 10gm of steam at 100C is 2.26x10^k J, then value of k is

Quantity of heat lost in condensation of 10 gm of steam at 100^@ C is

If there is no heat loss, the heat released by the condensation of x gram of steam at 100^@C into water at 100^@C can be used to convert y gram of ice at 0^@C into water at 100^@C . Then the ratio of y:x is nearly [Given L_l = 80 cal//gm and L_v= 540 cal//gm ]

If DeltaG° value of fuel cell using C_4H_10 and O_2 is -2.6×10^6 J,then E° value of cell is

Find the quantity of heat required to convert 2gm of ice at -10C into steam at "100C

1gm water at 100^(@)C is heated to convert into steam at 100^(@)C at 1atm . Find out chage in internal energy of water. It is given that volume of 1gm water at 100^(@)C = 1c c , volume of 1gm steam at 100^(@)C = 167 1 c c . Latent heat of vaporization = 540 cal//g . (Mechanical equivalent of heat J = 4.2J//cal)

50 gm of copper is heated to increase its temperature by 10^(@)C. If the same quantity of heat is given to 10 gm of water, the rise in its temperature is (Specific heat of copper =420 Joule-kg^(-1)@C^(-1)

The difference between the specific heat is 600 J/kg K. the ratio of their specific heats is 1.6. the value of c_(p) is . . ..J/kg K.

75 gm of copper is heated to increase its temperature by 10^@ C . If the same quantity of heat is given to 'm' gm of water, to have same rise in temperature is (specific heat of copper = 420 J//Kg-^@ C ).

2 gm of steam condenses when passed through 40 gm of water initially at 25”^(@)C The condensation of steam raises the temperature of water to 54.3”^(@)C .What is the latent heat of steam?

The heat of combustion of ethane gas at 373 k cal per mole. Assume that 50% of heat is lost, how many litres of ethane measured at STP must be convert 50 kg of water at 10^(@)C to steam at 100^(@)C ? One mole of gas oc cupies 22.4 litres at STP. Take latent heat of steam =2.25xx10^(6) j kg^(-1) .
