Learn about gas pressure and how it is used in daily life in this KS3 Chemistry guide from BBC Bitesize.

Heating a gas increases the kinetic energy of the particles, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated.

These five terms are: the pressure (P), volume (V), number of moles (n), a constant (R)—with a value of 8.3145 joules per kelvin-mole—and temperature (T). You can't understand the ideal gas ...

Researchers found that, during the unfiltered drives, the blood pressure increases were similar to those seen in the lab, of just under 5 millimeters of mercury.

The four fundamental states of matter are solid, liquid, gas and plasma, but there others, such as Bose-Einstein condensates and time crystals, that are man-made.
