4. compute the change in internal energy when 12 L of argon gas at 273 K and 1 atm is compressed to 6 L with the final pressure equal to 10 atm. Solve this problem in two different ways: a. derive the equation that relates the internal energy to pressure and volume and use it solve the problem. b. Use the information given to compute the final temperature of the gas and apply the general relation ΔU=CvΔT. Assume Cv=3/2 R for this monoatomic gas.

Units and Dimensions

Dimensions are the basic concepts of the measurement of quantities. Units are the means of expressing the dimensions. For instance, an area has a dimension of L2 and a unit of m2.
