Question

A steel cylender contain a sample of oxygen gas at a pressure of 1 atm and a temperarureof 25 C. what will be the pressure of the gas if the cylinder is heated to 621 C​

Answer 1

P1/T1=P2/T2

first convert C to Kelvin scale

25 becomes 298K

621 becomes 894K

now put the values in the above equation

1/298=P2/894

P2=894/298

Pressure comes out to be 3 atm

HOPE THIS HELPS!!!
