Question

Write a short essay on decreasing of temperature and increasing of pressure on gas

Answer 1

As opposed to molecules in a liquid or solid, those in a gas can move freely in the space in which you confine them. They fly about, occasionally colliding with one another and with the container walls. The collective pressure they exert on the container walls depends on the amount of energy they have. They derive energy from the heat in their surroundings, so if the temperature goes up, so does the pressure. In fact, the two quantities are related by the ideal gas law.


In a rigid container, the pressure exerted by a gas varies directly with temperature. If the container isn't rigid, both volume and pressure vary with temperature according to the ideal gas law.
