2. The form of the Ideal Gas Law that we used in class is pV = mRT, where p is absolute pressure, V is volume, R is the specific gas constant and T is absolute temperature in Kelvin (SI units) or Rankine (English traditional units). i. ii. iii. Starting with pV = mRT, use the definition of molar mass and derive an alternative form of the Ideal Gas Law: p = pRT Now use the definition of the specific gas constant to show that pV = nRuT Add these two additional forms of the Ideal Gas Law to your class notes for reference throughout the semester.

A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 287. kPa. The piston is now pushed down, compressing the gas, until the gas has a final volume of 3.60 L. Calculate the final pressure of the gas. Round your answer to 3 significant digits. piston cylinder gas kPa x10 Submit Assignment Continue 2021 McGraw Hill LLC. All Rights Reserved.
