Question #c1ba9

Answer 1

0.1428 calorie `gm^-1 C^-1`

Explanation:

With in a minute heat energy supplied by the burner will be `(H)` = `(20*60)` J or `1200` J or `(1200/4)` i.e `285.714` Calorie

So,if the solid mass of `m` increases it's temperature by `theta` due to this amount of heat energy,we can write,

`H=mstheta` (where s is its specific heat capacity)

Given. `m=25` gm and, `theta = 80`

So,we get,s = 0.1428 CGS units
