How many grams of ice at `0^@C` should be added to 200 gm. of coffee at `90^@C` to cool it to `60^@C`? (Assume that coffee-cup is not heated) specific heat of water = 1 c a l / g m ∘ C , Specific heat of coffee = 1.4 c a l / g m ∘ C

The specific heat of ice at 0^@C is

The specific heat capacity of water is ____kcal/kg °C

If 50 gm of water at 0^@C is added to 250 gm of water at 90^@C . Find the final temperature

30 gm of ice at 0^@C is placed in a calorimeter of mass 20 gm also at 0^@C . 100 gm of water at 90^@C is poured into the calorimeter. Find the final temperature. (specific heat of calorimeter = 0.4 cal//gm ^@C , Specific heat of water = 0.42 cal//gm ^@C Latent heat of fusion of ice = 80calg )

Steam at 100^@C is passed into 20 g of water at 10^@C When water acquires a temperature of 80^@C , the mass of water present will be Take specific heat of water= 1 cal g^-1^@ C^-1 and latent heat of steam = 540 cal g^-1 )

1 of a steam at 100^@C melts how much ice at 0^@C ? ( Latent heat of ice=80 cal/g and latent heat of steam =540 cal/g )

40 gm of water at 70^@C is poured into a calorimeter of mass 160 gm, which is at 20^@C . If the final temperature of the contents is 40^@C , what is the specific heat of the calorimeter? Specific heat of water = 4200 J /kg/C

How much energy needs to be supplied to 150 g of water at 100^@C to convert it to steam at 100^@C . (L=540 cal/g)

How much steam at 100^@C will just melt 1600 g of ice at -8^@C ? (Specific heat of ice= 0.5 (cal)/g^@C , specific heat of water= 1/cal/g^@C , latent of fusion of ice = 80 cal/g , and latent heat of vaporisation of water= 540 cal/g )

Find the heat required to convert 20 g of ice at 0⁰C into water at the same temperature . (Specific latent heat of fusion of ice = 80 cal/g)
