Explanation:

Whether you know it or not, compressed air is involved in every aspect of our lives, from the balloons at your birthday party to the air in the tires of our cars and bicycles. It was probably even used when making the phone, tablet or computer you’re viewing this on.

The main ingredient of compressed air is - you guessed it! - air. Air is a gas mixture, which means it consists of many different gases. Primarily these are nitrogen (78%) and oxygen (21%).

The temperature of the air is directly proportional to the mean kinetic energy of these molecules. This means that the air temperature will be high if the mean kinetic energy is large (and the air molecules move faster). The temperature will be low when the kinetic energy is small.

Compressing the air makes the molecules move more rapidly, which increases the temperature. This phenomenon is called “heat of compression”. Compressing air is literally to force it into a smaller space and as a result bringing the molecules closer to each other. The energy that gets released when doing this is equal to the energy required to force the air into the smaller space. In other words, it stores the energy for future use.

I am Lyosha [343]

Answer:

Explanation:

it's worth pointing out that the terms solute and solvent do not really apply here because sulfuric acid is miscible in water, meaning that the two liquids can be mixed in all proportions to form a homogeneous mixture, i.e. a solution.

If kinetic energy increases does pressure decrease?
enyata [817]

If molecules are in a closed container then we expect the pressure to increase as the kinetic energy increases. This is because the atoms of an element collide with the walls of the container and increase the pressure.

If we use the formula PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R the ideal gas constant and T is the temperature.  According to the formula, P is directly proportional to temperature. An increase in temperature leads to an increase in pressure.

Since we know that temperature is the average kinetic energy of molecules present. It means as we increase the temperature we increase the kinetic energy of the molecules which in turn leads to an increase in the pressure.
