![]() The process standard deviation is 6, and the mean is 170. Rounded to three sig figs, the number of sig figs you have for the initial pressure of the gas, the answer will be A certain process has an upper specification limit of 220 and a lower specification limit of 160. So, rearrange the equation to solve for #P_2# It's very important to remember that the temperature of the gas must be expressed in Kelvin! #P_2#, #T_2# - the pressure and temperature of the gas at a final state #P_1#, #T_1# - the pressure and temperature of the gas at an initial state This happens because if the molecules are moving at a higher average kinetic energy, they will hit the walls of the container with more force and more frequent #-># gas pressure will increase. When volume and number of moles of gas are kept constant, increasing the temperature of the gas will result in an increase in pressure - this is known as Gay Lussac's Law. ![]() This means that increasing the temperature of a gas is equivalent to increasing the average kinetic energy of its molecules. Now, temperature is actually a measure of the average kinetic speed of the gas molecules. The more powerful and frequent these collisions are, the higher the pressure exerted by the gas. As you know, gas pressure is caused by the collisions between the gas molecules and the walls of the container.
