1) What is the kinetic energy (in Btu) associated with a 300 gm hockey puck flying at 120 mph?

2) Assuming an ideal gas, calculate the specific volume in the appropriate units for (6 pts) : a. N² at 500 kPa and 900 K b. Neon at 8 kPa and 250 K c. Air at 100 kPa and 298 K

3) Calculate the specific enthalpy change (in the appropriate units) for the following ideal gas processes by first using an average c P and then by using the ideal gas tables. (12 pts) a. CO² at 2000 kPa goes from 500 K to 1300 K b. CO² at 2000 kPa goes from 500 K to 600 K c. Air at 320 kPa and 330 K goes to 80 kPa and 330 K

4) Carefully draw the following graph using air as an ideal gas. (10 pts) a. temperature versus pressure showing lines of constant specific volume and specific enthalpy

5) Calculate the entropy change for N² as it goes from 250 K and 1000 kPa to 1300 K and 60 kPa.
