18.16 Three moles of an ideal gas are in a rigid cubical box with sides of length 0.2m. (a) what is the force that the gas exerts on each of the six sides of the box when the gas temperature is 20°C? (b) What is the force when the temperature of the gas is increased to 100°C? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB

18.36 The atmosphere of Mars is mostly CO2 (molar mass 44 g/mol) under a pressure of 650 Pa, which we shall assume remains constant. In many places the temperature varies from 0°C in summer to -100°C in winter. Over the course of a martian year, what are the ranges of (a) the rms speeds of the CO2 molecules, and (b) the density (in mol/m3) of the atmosphere?

18. 41 (a) How much heat does it take to increase the temperature of 2 18.41 (a) How much heat does it take to increase the temperature of 2.5 mol of a diatomic gas by 30K near room temperature if the gas is held at constant volume? (b) What is the answer to the question in part (a) if the gas is monatomic rather than diatomic? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB
