Gas laws are relationship between the measurable properties of gases. A definite quantity of an ideal gas is confined in a container of constant volume. When the container is immersed in a bath of melting ice, the pressure of the gas is 800mm of Hg. Find the temperature when the gas pressure is 400mm of Hg.

1.	Gas laws are relationship between the measurable properties of gases. A definite quantity of an ideal gas is confined in a container of constant volume. When the container is immersed in a bath of melting ice, the pressure of the gas is 800mm of Hg. Find the temperature when the gas pressure is 400mm of Hg.
Answer» SOLUTION :`p_1/T_1 = p_2/T_2` `p_1 = 800 `MM of Hg,`p_2` = 400 mm of Hg `T_1` = 273K,`T_2 = ? LT`Substituting we get 800/273 = `400/T_2` `800xxT_2` = `273xx400` `therefore T_2 = (273xx400)/800` = 136.5K = 136.5-273 = `-136.5^@C`
