State the relationship between heating, temperature and pressure.

Answer

There is a close relationship between heating, temperature and pressure. The hot air raises the temperature and lowers the pressure. As we know that hot air is light and hence it exerts less pressure.

The heated air rises up and its water vapour condenses and falls as rain. Thus, the regions of high temperature and low pressure remain cloudy and get comparatively more rain.

The relationship between temperature and pressure is summarised as:


i. High temperature - Low pressure

ii. Low temperature - High pressure
