Ideal gas law
Compress it, heat it or add more gas, and watch how the pressure responds.
A given amount of ideal gas obeys the equation of state pV = nRT. At constant volume, pressure is proportional to absolute temperature; at constant temperature, pressure is inversely proportional to volume. The particle animation only illustrates the trend of thermal motion.
Isothermal pressure vs. volume
Temperature and amount of substance use the current settings; the curve shows Boyle's law.
Think about it
Keeping the volume and amount of substance fixed, if the absolute temperature is increased to 2 times its original value, how does the pressure change?
The pressure increases to 2 times its original value. From p = nRT/V, p is proportional to T when n and V are constant.
