Problem 1: Consider the two-sided chamber shown,where the right half has a volume of V = 590 L and the left half has a volume of 2V. The chamber has a seal which separates the right from the left half. The chamber is sealed and an ideal gas is pumped into the right side at a pressure P= 6.4 atm and temperature T= 78° C. The seal between the two sides is then opened. 2V V Part (a) If the physical temperature decreases by a factor of 2 while the gas fills the chamber, what is the new pressure, in kilopascals?

Hint Feedback Part (b) The chamber is then sealed again, trapping 2/3 of the gas molecules in the left side. The temperature of the left side is then doubled, back to the original temperature T. What is the pressure in the left side of the chamber now, in kilopascals?

In everyday experience, the measures of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by the following formula. F = 1.8C + 32 Physicists and chemists often use the Kelvin temperature scale. You can get kelvins K from degrees Celsius by using the following formula. K = C + 273.15 (a) Calculate that value.K(25) = (b) Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins. C = (c) Find a formula expressing the temperature F in degrees Fahrenheit as a function of the temperature K in kelvins. F =  (d) What is the temperature in degrees Fahrenheit of an object that is 272 kelvins?
