1500 ml of a gas at a room temperature of 23°C is inhaled by a person whose body temperature is 37°C, if the pressure stays constant, what will be the volume of the same gas in the lungs of the person (approx.).

Options:

Answer:

Solution:

Since pressure and amount of gas are kept constant,

$\frac{V _{1}}{T _{1}} = \frac{V _{2}}{T _{2}}$

$V_{2} = V_{1} \times \frac{T _{1}}{T _{2}}$

Here,

$T_{1} = 273 + 37 = 310 K, T_{2} = 273 + 23 = 296 K$

$V_{2} = 1500 \times \frac{310}{296} = 1570.95 l i t re$
