How much heat would be released by a 60 g iron body (specific heat `=0.12 cal//g//""^(@)//C)` when its temperature is reduced from `200^(@)C` to `100^(@)C` ?

Mass of object is 200g and its specific heat is "0.09 cal. g"^(-1).^(@)C^(-1) . How much that heat is required to increase its temperature from 20^(@)C to 90^(@)C ?

Mass of an object is 200 gm and specific heat 0.09 calorie/gm C . To rise temperature of that object from 20^@C to 90^@C how much heat is required?

A liquid at 25^(@)C , of specific heat "0.48 cal. G"^(-1).^(@)C^(-1) , is mixed with another liquid at 10^(@)C of specific heat "0.36 cal. g"^(-1).^(@)C . If the final temperature of the mixture is 20^(@)C , find the mass ratio of the two liquid in the mixture.

In which case more heat is required ? (i) Temperature of 1 kg of water is raised from 30^(@)C to 100^(@)C . (ii) Temperature of 3 kg of iorn, is raised from 30^(@)C to 230^(@)C . (specific heat of iron ="0.12 cal.g"^(-1).^(@)C^(-1) .)

For a body of mass m and specific heat capacity s, how much heat is required to increase its temperature by t?

The amount of heat required by 1 g of a substance for its 1^(@)C rise in temperature is called its
