State the name of the lowest possible temperature, which is designated as 0 K0\text{ K}0 K.
Oxygen boils at 90 K90\text{ K}90 K. Calculate the boiling point of oxygen on the Celsius scale.
The temperature of a fixed mass of gas in a rigid container of constant volume is decreased from 360 K360\text{ K}360 K to 270 K270\text{ K}270 K.
State and explain, in terms of particles, the effect of this temperature change on the pressure of the gas.
A sample of gas is at an initial pressure of 240 kPa240\text{ kPa}240 kPa. The volume of the gas is tripled while holding its temperature constant.
Calculate the new pressure of the gas.
