Question

At what Kelvin temperature will a sample of gas occupy 12 liters if the same sample occupies 8 liters at 27 ℃?

Answer 1

`T_1=450K`

Explanation:

Since the gas it is getting compressed with a change on temperature, we consider that the pressure is constant, and of course the number of mole is constant (same gas), therefore, from the ideal gas law `PV=nRT` we can say:

`V/T=" constant"`

Therefore, `(V_1)/(T_1)=(V_2)/(T_2)=>T_1=V_1xx(T_2)/(V_2)`

`=>T_1=12cancel(L)xx(300K)/(8cancel(L))=450K`
