Document Summary

Relating pressure, volume, amount, and temperature: the ideal gas law. P-t relationship for gases is known as either a(cid:373)o(cid:374)to(cid:374)s"s la(cid:449) or gay-lussac"s law. it states that the pressure of a given amount of gas is directly proportional to its temperature on the kelvin scale when the volume is held constant. The volume increases as the temperature increases, and decreases as the temperature decreases. Volume-temperature data for a 1-mole sample of methane gas at 1 atm are listed and graphed below. Charles"s la(cid:449) states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale when the pressure is held constant. Volu(cid:373)e a(cid:374)d pressure: boyle"s la(cid:449) (cid:2869)(cid:2869) = (cid:2870)(cid:2870) Decreasing the volume of a contained gas will increase its pressure, and increasing its volume will decrease its pressure. In fact, if the volume increases by a certain factor, the pressure decreases by the same factor, and vice versa.
