Apply sunscreen with a high SPF to protect your skin from UV (ultraviolet) rays
Over the last few days, NASA has been getting everybody excited with its plans to hold a high profile briefing about a discovery beyond our solar system. Now we know that the announcement concerns the discovery of seven planets orbiting a star elsewhere in our galaxy<span>. hope this helps</span>
Pressure is inversely proportional to volume. Therefore, the effect of pressure change is opposite to the effect of volume change. So when more gas is added to the chamber the total pressure of the chamber doesn't increase.
<h3>What are the different relations between pressure and volume?</h3>
- As the volume changes, the concentrations and partial pressures of both reactants and products change.
- As the volume decreases, the reaction shifts to the reaction side with fewer gas particles.
- As the volume increases, the reaction shifts to the side of the reaction containing more gas particles.
- As the pressure increases, the equilibrium shifts towards reactions with fewer moles of gas.
- As the pressure decreases, the equilibrium shifts to the side of the reaction with higher moles of gas.
- Moreover, the pressure change in the system due to the addition of the inert gas is not limited to this.

<u>Collisions between gas particles and the object</u> is the reason a gas exerts pressure on the object.
Explanation:
Gas molecules usually have higher kinetic energy than that of liquid and solids. These molecules, therefore, collide with other molecules of the gas and if the gas is held in a container, the gas molecules will also collide with the walls of the container. As the kinetic energy of the gas molecules increases, due to increased energy input in the gas, so does the energy of collisions between the molecules and the molecules with the walls of the container. This is how the pressure of a gas in a container increases with an increase in temperature.
Even though the gas molecules are tiny, the numerous collisions by the billions of gas molecules of the gas apply a cumulative pressure.
