Which of the following would represent the greatest pressure? 74141 Pa 18.3 in Hg O 518 mmHg O 12.1 psi 0.603 atm

If a sample of carbon dioxide gas in a 455.0 ml container has a pressure of 725.0 mmHg at -49.0oC, what would be the pressure at 115.0oC?

Pam The pressure of a sample of gas is measured with an open- ended manometer, shown to the right. The atmospheric pressure is 758 mm Hg. The liquid in the manometer is mercury. What is the pressure of the gas in mm Hg? (1 cm 10 mm) 1. Gas Open end 5.13 cm The total pressure in a tire is 1.20 atm at 23.0 °C. If the temperature is increased to 47.0 °C, what is the new pressure in the 2. tire? Assume the volume of the tire does not change.
