The calculated answer is 0,99atm Now, as gases' kinetic energies rise, more particles are colliding with one another.
Applying Gay-principle Lussac's
P₁T₂ = P₂T₁
P1: 0.70 atm, T2: 425K, P2:??, and T1: 299K
425K / 299K 0,70 atm = 0,99 atm
The kinetic energy of gas particles grows with temperature according to the kinetic molecular theory, and as kinetic energy rises, pressure rises as well. That indicates that as the temperature rises, the pressure within the system rises.
Now, as gases' kinetic energies rise, more particles are colliding with one another. The observed pressure will differ from the pressure predicted by ideal gas law due to the intermolecular forces that ideal gas law does not account for.
