the relationship of the different properties of gas

STANDARD TEMPERATURE & PRESSURE

• 273 K

• 1 atm

the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.

1662, Robert Boyle

V₁P₁ = V₂P₂

A balloon contains 7.2 L of He. The pressure is reduced to 2.00 atm and the balloon expands to occupy a volume of 25.1 L. What was the initial pressure exerted on the balloon?

volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
