Answer 2

Given:

The quantity of heat required to raise the temperature of 25 g of ethylene glycol by 1K is 60.8 J.

To find:

Specific Heat capacity of ethylene glycol?

Calculation:

Specific heat capacity is defined as the heat required to raise the temperature of unit mass of a substance by 1 Kelvin.

• Let heat required be H , m be mass, c be specific heat capacity and $\Delta\theta$ be change in temperature [/tex].

$\boxed{ \sf \therefore \: H = m \times c \times \Delta \theta}$

$\sf \implies\: 60.8= 25\times c \times1$

$\sf \implies\: c = \dfrac{60.8}{( \frac{25}{1000} )}$

$\sf \implies\: c = 2432 \: J{K}^{ - 1} {kg}^{ - 1}$

So, the specific heat capacity for ethylene glycol is 2432 J/(kg K)
