Gas laws
the absolute temperature of a gas is increased four times while maintaining a constant volume. what happens to the pressure
of the gas?

The pressure of the gas increases by the four times.

Explanation:

According to the Gay-Lussac's law

The relationship between pressure and temperature is as follows.

\

From the given data, we considered 1 is a initial temperature and 4 is final  temperature. Initial pressure is considered as .

Let's find the final pressure of the gas.

Substitute the temperature value.

Therefore, The pressure of the gas increases by the four times.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
