Driving slowly down a two-lane highway a large transport truck passes me going the same way as I am. As he does physics flashes before my eyes, and I think Bernoulli’s principle with pressure and...
If a contained ideal gas decreases the volume by a factor of two and then triples the temperature, what happens to the pressure? a. It goes up by a factor of 2 b. It goes up by...
On a phase diagram there is a triple point, where solids liquids and gasses all exist at the same temperature and pressure. If I decrease the temperature but increase the pressure from this triple...
If a tank has 2.50 g of N2 (nitrogen atom has 14 nucleons) and a volume of 1950 cm3 and it is held at 142 0 C, what is the pressure?
Initially, only H2S is present at a pressure of 0.148 atm in a closed container. What is the total pressure in the container at equilibrium? H2S(g) ---> (and the reverse arrow) H2(g)+S(g) HINT: You...
An unknown gas is placed in a cylinder that has a movable piston. The volume of the cylinder is set at 6.0 L and the resulting pressure is 735 mm Hg. The piston is pushed into the cylinder and the...
A 15 litre cylinder contains 0.35kg of butane gas (C4 H10). Assuming ideal gas behaviour, calculate the pressure of the gas if the cylinder is stored at 50 Fahrenheit.
PRESSURE HELP! The vapor pressure of liquid iodomethane, CH3I, is 100. mm Hg at 266 K. A 0.541 g sample of liquid CH3I is placed in a closed, evacuated 490. mL container at a temperature of 266...

Interstellar space far from any stars is usually filled with a atomic hydrogen (H) at a number density of 1 atom per cubic centimeter and very low temp of 2.7K. Determine the...
When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV^(1.4)=C where C is a constant. Suppose that at a certain instant the volume...
