In an experiement on the specific heat of a metal a 0.20 kg block of the metal at `150^(@)C` is dropped in a copper calorimeter (of water equivalent 0.025 kg) containing `150cm^(3)` of water at `27^(@)C`. The final temperature is `40^(@)C`. Compute the specific heat (in `Jkg^(-1)""^(@)C^(-1)`) of the metal.

In an experiment to determine the specific heat of a metal, a 0.20 kg block of the mental at 150 .^(@) C is dropped in a copper calorimeter (of water equivalent 0.025 kg containing 150 cm^3 of water at 27 .^(@) C . The final temperature is 40.^(@) C . The specific heat of the metal is.

In an experiment on the specific heat of a metal a 0.20 kg block of the metal at 150^(@) C is dropped in a copper calorimeter (of water equivalent 0.025 kg) containing 150 cc of water at 27^(@) C. The final temperature is 40^(@) C. Calcualte the specific heat of the metal. If heat losses to the surroundings are not negligible, is our answer greater or smaller than the actual value of specific heat of the metal?

In an experiment to determine the specific heat of aluminium, piece of aluminimum weighing 500 g is heated to 100 .^(@) C . It is then quickly transferred into a copper calorimeter of mass 500 g containing 300g of water at 30 .^(@) C . The final temperature of the mixture is found to be 146.8 .^(@) c . If specific heat of copper is 0.093 cal g^-1 .^(@) C^-1 , then the specific heat aluminium is.

In a laboratory experiment to measure the specific heat capacity of copper, 0.02 kg of water at 70^(@)C was poured into a copper calorimeter with a stirrer of mass 0.16 kg initially at 15^(@)C .
