Any attempt is appreciated. i really need . use the kinetic theory of gases to explain: 1. a gas exerts a pressure on the walls of the container in which it is stored. 2. the pressure of a gas inside a metal container increases as the temperature of the container incresases.

2. A gas particle has kinetic energy in proportion to its speed; the faster it is moving, the greater its kinetic energy.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
