m' kg of a substance of specific beat capacity `J//kg^@C` is heated, so that its temperature rises from `theta_1^@C` to `theta_2^@`C. Write down the expression for the heat Q supplied.

Text Solution

Verified by Experts

Heat supplied (Q) = mass x specific heat capacity x rise in temperature
`therefore Q= m xx s xx (theta_2-theta_1)`
