50 cm3 of a gas are in
20°C calculate the
new volume at 96°C

Answer 1

Given :

Volume of gas in 20°C is 50 cm³.

To Find :

The  new volume at 96°C.

Solution :

Let, us assume that the pressure is constant throughout the process.

We know, when pressure is constant volume is directly proportional to the temperature.

So, $\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}$

Putting all values in above equation, we get :

$\dfrac{50}{V_2}=\dfrac{273+20}{273 + 96}\\\\V_2 = 50\times \dfrac{369}{293}\ cm^3\\\\V_2 = 62.97\ cm^3$

Hence, this is the required solution.
