at constant volume, the pressure in a cylinder of gas is 345 kpa at a temp of 27 celsius what would be the pressure of this cylinder of gas if the temp changes in hot sun to 47 c°

how do i solve and what's answer
will give brainliest

The Ideal Gas Law states that PV=nRT where P is pressure, V is volume, n is number of molecules, R is the gas constant and T is the temp.

As number of molecules does not change and volume of cylinder does not change, we move the constants to one side: P/T=nR/V=constant.

We get P1/T1=P2/T2

Temp should be in K so T1=27C+273=300K

T2=47C+273=320K

P2=T2*P1/T1=320*345/300

=368kPa
