Question

A gas at constant pressure occupies 900 ml at 30°C. What would the volume be
at 45°C?

Answer 1

1350 mL

Step-by-step explanation:

Given that,

Volume, V₁ = 900 mL

Temperature, T₁ = 30°C

We need to find the new volume if the temperature is 45°C. The relation between temperature and volume is direct (Charles's law).

`(V_1)/(V_2)=(T_1)/(T_2)\\\\V_2=(V_1T_2)/(T_1)\\\\V_2=(900* 45)/(30)\\\\V_2=1350\ \text{mL}`

So, the new volume is 1350 mL.
