Because gas can be compressed. One example is the bicycle pump. Put one finger over the exit hole, and push the handle down until it can't go further. The air inside the pump is now occupying a smaller space.
As more gas molecules are forced into a confined space, the pressure within the space will increase. This is because the molecules will collide more frequently with the walls of the container, exerting more force per unit area. If the pressure becomes too high, the container may rupture.
It keeps on bouncing on the wall until its energy is converted into motion.
They start to condense
pressure will increase
Molecules take up less space as they cool. The space contains more molecules.
pressure exerted by a vapor confined within a given space
When a latex balloon is filled with 3L of air, the air molecules are forced into the balloon, increasing the pressure inside. The latex material stretches to accommodate the increased volume of air, as the rubber molecules are pulled apart to allow space for the air molecules. Once filled, the pressure inside the balloon causes it to expand and hold its shape.
attraction to the positively charged nucleus
A sample of gas confined in a sealed container will distribute itself evenly throughout the container, filling the available space. The gas molecules will continuously move and collide with each other and the container walls, exerting pressure on the walls due to their random motion.
It expands, taking up more space, if there is no more space, pressure in the container increases.
Molecules take up less space as they cool. The space contains more molecules.
Confined space is an area that is enclosed. A dog kennel could be a confined space for a dog. A living room is a confined space for example.
When a solid dissolves in a solvent, the intermolecular forces holding the molecules in the solid lattice break. The solvent molecules surround the solute molecules, causing them to separate and disperse evenly throughout the solvent. The solute molecules become completely surrounded by solvent molecules in a process called solvation.

There is currently a sale on confined space gas detectors at pksafety. They have several models to choose from: http://www.pksafety.com/confined-space-gas-detectors.html
an authorized employee responsible for determining whether acceptable entry conditions are present in a confined space before authorizing entry; overseeing the confined space operation, and terminating the confined space entry
ensure that a qualified person evaluates and classifies the confined space
Confined space is an area which is enclosed with limited access which makes it a dangerous place to be in. Therefore, confined space rescue refers to techniques to save people whos been trapped in confined spaces.

A confined space is an enclosed area that has limited access and may have a risk of hazardous conditions such as poor ventilation or the presence of toxic substances. Examples include storage tanks, sewers, and tunnels. Proper precautions and safety measures should be taken when working in confined spaces to prevent accidents or injuries.
