理想气体定律

变量说明

P= pressure (Pa)V= volume (m³)n= moles of gasR= gas constant = 8.314 J/(mol·K)T= temperature (Kelvin)

Ideal gas law

The fundamental relationship PV = nRT.

Solve for each variable

Rearrange for any unknown.

Find P
Find V
Find n
Find T

Combined gas law

Relates two states of the same gas sample.

Convert temperature

The gas law requires temperature in Kelvin.

专业提示

Always verify your input values before calculating. For ideal gas law, small input errors can compound and significantly affect the final result.

难度:初级

你知道吗?

At standard conditions (0°C, 1 atm), 1 mole of any ideal gas occupies exactly 22.414 litres — the molar volume.
