Question

At an absolute temperature of 300ka certain mass of gas occupies 1m3.find the volume of the gas when the absolute temperature is 375k

Answer 1

The equation of states for an ideal gas says

$$PV=nkT$$

If the pressure is constant we obtain

$$\frac{V_2}{V_1}=\frac{T_2}{T_1}$$

So

$$V_2=V_1\frac{T_2}{T_1}$$

$$V_2=1\:\rm m^3\times \frac{375\:\rm K}{300\:\rm K}=1.25\:\rm m^3$$
