Calculate the specific heat of a metal (in calories/gram-degree C) from the following data. A container made of the metal has a mass of 3.10 kg and contains 11.1 kg of water. A 1.10 kg piece of the same metal, initially at a temperature of 140 degrees C, is placed in the water. The container and water initially have a temperature of 15 degrees C, and the final temperature of the entire system is 18 degrees C.
Specific heat of water
Let the specific heat of metal
Mass of the block
Initial temperature of metal block
Final temperature of metal block
∴ Heat lost by metal block
Container is made of same metal.
So, specific heat of container = specific heat of metal
So, specific heat of container
Mass of the container
Initial temperature of container
Final temperature of container
∴ Heat gained by container
specific heat of water
Mass of the water
Initial temperature of water
Final temperature of water
∴ Heat gained by water
By conservation of energy,
Heat gained by water + Heat gained by container = Heat lost by metal block
So, the specific heat of metal
