Question

at constant temperature the volume of a fixed mass of co2 is 1000 ml 380 mm pressure if 1000 mm pressure is applied at the same temperature what will be the volume of the gas

Answer 1

Answer : The volume of gas will be, 380 ml

Solution :

According to the Boyle's law, the pressure of a gas is inversely proportional to the volume of gas at constant temperature.

$P\propto \frac{1}{V}$

$P_1V_1=P_2V_2$

where,

$P_1$ = initial pressure of gas = 380 mmHg

$P_2$ = final pressure of gas = 1000 mmHg

$V_1$ = initial volume of gas = 1000 ml

$V_2$ = final volume of gas

Now put all the given values in this formula, we get the final volume of gas.

$(380mmHg)\times (1000ml)=(1000mmHg)\times V_2$

$V_2=380ml$

Therefore, the volume of gas will be, 380 ml
