The water equivalent of a copper calorimeter is 4.5g. If the specific heat of copper is 0.09 cal `g^(-1).^(@)C^(-1)`. Then

Find the water equivalent of copper block of mass 200 g . The specific heat of copper is 0.09 cal g^(0) C .

Mass of a calorimeter made of copper is 80 g. If the specific heat of copper is "0.09 cal. g"^(-1).^(@)C^(-1) , determine the thermal capacity and water equivalent of the calorimeter?

The water equivatent of a 400 g copper calorimeter (specific heat =0.1 "cal"//g^(@)C )

The water equivatent of a 400 g copper calorimeter (specific heat =0.1 "cal"//g^(@)C )

A body of mass 100 g is heated up to 122^(@)C and dropped quickly in water of mass 300 g kept at 28^(@)C in a copper calorimeter of mass 50 g. The final temperature of the mixture becomes 30^(@)C. If the specific heat of copper is "0.09 cal.g"^(-1).^(@)C^(-1) , find the specific heat of the material of the body.

About 5g of water at 30^(@)C and 5g of ice at -20^(@)C are mixed together in a calorimeter. Calculate final temperature of the mixture. Water equivalent of the calorimeter is negligible. Specific heat of ice =0.5"cal"g^(-1)C^(@)-1) and latent heat of ice =80"cal"g^(-1)
