Which of the following statements is true about the ideal gas law?

What is the final pressure of a gas whose initial pressure is 590 torr, initial temperature is 308 K, and final temperature is 286 K? Assume volume and amount of gas are held constant.

When applying Charles's law, amount of gas and volume are considered to be constants.

One torr is an equivalent unit of one millimeter of mercury, the amount of pressure exerted by a column of mercury exactly 1 mm high.

The _____ theory of gases is a fundamental model that describes the physical properties of gases.

_____ is defined as exactly 100 kPa of pressure (0.986 atm) and 273 K (0°C).

A gas has an initial volume of 65.08 mL and an initial temperature of 577°C. What is its new volume if temperature is changed to 417°C? Assume pressure and amount of gas are held constant.

An ideal gas is a gas that exactly follows the statements of the kinetic theory.

CO₂ generated by the decomposition of ZnCO₃, is collected in a 5.6 L container over water. If the temperature is 40.0°C and the total pressure inside the container is 580 torr, how many moles of CO₂ were generated?

What are the postulates of the kinetic theory of gases?

A 6.00 mol sample of O₂ has a pressure of 0.80 atm and a temperature of 68°C. Its volume is 41.8L.
