A sample of hydrogen gas at a pressure of 977 mm Hg and a temperature of 32 °C, occupies a volume of 11.3 liters. If the gas is cooled at constant pressure to a temperature of -5 °C, the volume of the gas sample will be L.

Answer : The volume of gas sample will be, 9.93 L

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles of gas.

Mathematically,

where,

are the initial volume and temperature of the gas.

are the final volume and temperature of the gas.

We are given:

Now put all the given values in above equation, we get:

Therefore, the volume of gas sample will be, 9.93 L

have a great day because if you dont you and i will be sad

the answer is true. hope it .
