PHYS 153 Homework 3A Problem 1 A nebula – a region of the galaxy where new stars are forming – contains a very tenuous gas with 100 atoms / cm 3 . This gas is heated to 7500 K by ultaviolet radiation form nearby stars. What is the gas pressure in atm? (assume gas density stays constant) Problem 2 8 . 0 g of helium gas follows the process 1 -→ 2 -→ 3 shown in the figure. Find the values of V 1 , V 2 , p 2 , and T 3 . Problem 3 The atmosphere of the planet Mars is 95 . 3% carbon dioxide (CO 2 ) and about 0 . 03% water vapor. The atmospheric pressure is only about 600 Pa, and the surface temperature varies from - 30 C to - 100 C. The polar ice caps contain both CO 2 ice and water ice. Could there be liquid CO 2 on the surface of Mars? Could there be liquid water? Why or why not? 1 - 1

Unformatted text preview: Problem 4 . 0050 mol of gas undergoes the process 1- 2- 3 shown in the gure. What are (a) temperature T 1 , (b) pressure p 2 , and (c) volume V 3 ? Problem 5 10 g of dry ice (solid CO 2 ) is placed in a 10 , 000 cm 3 container, then all the air is quickly pumped out and the container sealed. The container is warmed to 0 C, a temperature at which CO 2 is a gas. (a) what is the gas pressure? Give your answer in atm. The gas then undergoes an isothermal compression until the pressure is 3 . 0 atm, immediately followed by an isobaric compression until the volume is 1000 cm 3 . (b) What is the nal temperature of the gas (in C)? (c) Show the process on a pV diagram. 1 - 2...
