5.11 understand why there is an absolute zero of temperature which is –273oC

Temperature affect the pressure of particles of gases. The higher the temperature, the higher the energy in particles and more the pressure. If we decrease the temperature the result will be the exact opposite. As we cool the gas, the pressure keeps decreasing. The pressure of the gas cannot become less than zero. The temperature at which the pressure of the gas is decreased to 0, that temperature is called absolute zero. It is approximately –273oC.
