Question

The sp. heat of a substance varies with temperature tºC as C = (0.2 + 0.16t) cal/gmºC. The heat required to raise the temperature of 5gm substance from 5°C to 10°C will be:
1) 24 cal 2) 35cal 3) 56 cal 4) 100cal
can anyone pls tell me how to solve this??​

Answer 1

Answer:

Specific heat of substance is equal to heat gain or released by that substance to raise or fall its

temperature by 1ºC for a unit mass of substance.

When a body is heated, it gains heat. On the other hand, heat is lost when the body is cooled. The gain

or loss of heat is directly proportional to:

(a) the mass of the body Q  m

(b) rise or fall of temperature of the bod
