Question

A fixed volume container is filled with some amount of nitrogen gas and then the container is sealed. The pressure is measured to be 1 atm when the temperature is                100 K. Choose all that are correct from the following.

If the temperature is decreased to 50 K, the pressure would be 0.5 atm.

If the temperature is decreased to                50 K, the pressure would be 0.25 atm.

If the temperature is increased to 200 K, the pressure would be 4 atm.

If the temperature is increased to 200 K, the pressure                would be 2 atm.

Explanation / Answer

PV=nRT

Since n,V and R are constant

Pressure is directly proportional to temperature

So 1and 4 are correct
