A calorimeter has mass 100 g and specific heat 0.1 `kcal//kg^@C`.It contains 250 gm of liquid at `30^@C` having specific heat of 0.4 `kcal//kg^@C`. If we drop a Piece of ice mass 10 g at `0^@C`, what will be the temperature of the mixture?

The specific heat of ice at 0^@C is

A copper calorimeter of mass 100g and temperature 30⁰C contains water of mass 200g and temperature 30⁰C. If a piece of ice of mass 40g and temperature 0⁰C is added to it,What will be the maximum temperature of the mixture ? [ c (copper)= 0.1 cal/g ⁰C, C (water) = 1 cal/g ⁰C , L= 80cal/g ]

A calorimeter of mass 50 gm and specific heat capacity 0.42 J g^-1 ^@C^-1 contains some water at 20^@ C. A metal piece of mass 20 gm at 100^@ C is dropped into the calorimeter. After stirring, the final temperature of the mixture is found to be 22^@C .Find the mass of water used. (specific heat of metal piece= 0.3 J g^-1 ^@C^-1 specific heat of water = 4.2 J g^-1 ^@C^-1 )

If water of mass 60g and temperature 60⁰C is mixed with water of mass 60g and temperature 40⁰C , what will be the maximum temperature of the mixture ?

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

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 )

Water of mass 200g and temperature 30⁰C is taken in a copper calorimeter of mass 50g and temperature 30⁰C .A copper sphere of mass 100g and temperature 100⁰C is released into it. What will be the maximum temperature of the mixture ? [ c (water)= 1 cal/g ⁰C, C (copper) = 0.1 cal/g ⁰C ]

Solve the following examples / numeriacal problems: If water of mass 80 g and temperature 45⁰ C is mixed with water of mass 20 g and temperature 30⁰C . What will be the maximum temperature of the mixture ?
