Problem 2. The gauge pressure in your car tires is 2.50 x 105 N / m2 at a temperature of 35.0 C when you drive it onto a ferry boat to Alaska. What is their gauge pressure later, when their temperature has dropped to -40.0 C? Problem 3. An expensive vacuum system can achieve a pressure as low as 1.00 X 10'7 N/rn2 at 20 C. How many atoms are there in a cubic centimeter at this pressure and temperature
