Question

If the volume of a fixed mass of a gas at 27 degree celsius is doubled at constant presssure what is the new temperature​

Answer 1

Answer:

For a fixed mass of gas at constant temperature, the volume is inversely proportional to the pressure. That means that, for example, if you double the pressure, you will halve the volume. If you increase the pressure 10 times, the volume will decrease 10 times.

Answer 2

Given: The volume of a fixed mass of a gas at 27 degrees celsius is doubled at constant pressure.

To find: We have to find the new temperature.

Solution:

According to the law of ideal gas PV=nRT.

Where P is the pressure, V is the volume of the gas. T is the temperature of the gas and n is the number of moles.

At constant pressure and mass, the volume of the gas is directly proportional to temperature.

The initial temperature of the gas is 27+273=300K.

So, we can write-

$\frac{v}{300} = \frac{2v}{x} \\ x = 600$

The temperature of the gas is 600K.
