Basically, pressure is just a way to quantify the overall effect of many particles colliding with the side of a container. Each collision of particle and container transfers a force into the container. When particles have a higher speed they cause more acceleration and therefore more force into the container. Since pressure is the force per unit area, when the force increases, so does the pressure. So basically, the higher the particle speed, the higher the pressure.

Does a liquid turn into a gas when the particles speed up?
Yes. A liquid turns into a gas when the particles speed up. When the particles in the liquid start going at a faster speed than the forces of cohesion in the liquid can hold them in the liquid and the air pressure can continue to push them into the liquid, they leave the liquid.
What are different ways to manipulate air pressure?
Five ways:Temperature (increase in temperature means increase in pressure.)Velocity (increase the speed means decrease in pressure.)Amount of air particles (more particles means more pressure.)Changing the container (More space means less pressure.)Altitude (increase in altitude means decrease in pressure.)
Adding energy or increasing the speed of the particles at very low pressure in a solid would cause?
to either melt of explode
If you wanted to predict how temperature will effect the volume of a gas what factors must be held constant?
If temperature increases, then pressure increases. Temperature measures the average speed of particles, so if the temperature is high, then the particles are moving quickly and are colliding with other particles more forcefully. Pressure is defined as the force and number of collisions the particles have with the wall of its container. So if the high temperature causes the particles to move quickly, they are going to collide more often with the container, increasing the pressure. This remains true as long as the number of moles (n) remains constant.
What happens when the temperature of a gas increased?
If you increase the temperature of a gas, its particles (atoms or molecules) will speed up. If it is in a closed container, the pressure will also increase.
What happen when The greater the speed of gas particles in a container the?
greater the pressure
What happens to the speed of the gas particles when pressure is applied?
is move themselves
The greater the speed gas particles in a container the?
The greater the speed of gas particles in a container, the higher the overall average temperature and kinetic energy of the gas particles. And if volume was held constant, higher the pressure.
What happens to the speed of gas when heated?
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
Does a liquid turn into a gas when the particles speed up?
Yes. A liquid turns into a gas when the particles speed up. When the particles in the liquid start going at a faster speed than the forces of cohesion in the liquid can hold them in the liquid and the air pressure can continue to push them into the liquid, they leave the liquid.
How do gas particles exert pressure on their container?
'This is because the air particles are bumpinginto each other and the walls. When this happens it causes pressure on the walls because of the speed the air particles are moving

Does air flow from areas of higher pressure to areas of lower pressure?
Air will flow from areas of high pressure to areas of low pressure. Pressure = force/area. So in this context, air pressure is the force the particles in that area exert on the space around them (let's imagine they're in a box). As air particles whizz around, they will collide with the edges of the box, so bouncing off and changing direction. This direction change involves a lot of acceleration (though speed may be the same, velocity (which is speed in a specific DIRECTION) will be very different. Physics tells us F=MA. Therefore, this acceleration will equate to a force on the outside world. This force will therefore be proportional to the number of particles in the area (more particles = more area). So, if an area of high pressure has lots of particles, there will be a spreading out of these particles to areas of low particles (diffusion, and energy's natural tendency to spread out). Alternatively, think of it as particles in the high pressure area pushing against the particles from the low area, and they're pushing force being greater, so they win! There you have a very long winded answer for why air moves from high pressure to low pressure!
What happens when gas and heat combine?
The gas particles will gain more kinetic energy and speed up. If they are in a closed container, the increased speed of the particles will make the particles hit the sides of the container more often, increasing the pressure inside of the container. On cursory inspection at the macroscopic level, the result is hot gas.
What is kinetic theory and how is it used?
Kinetic theory is when a high number of particles such as temperature, viscosity and volume that move randomly colliding in different directions. The speed of particles has an impact on temperature and gas pressure.
What is the average speed of the particles of a substance?
The average speed of the particles in a substance is the definition of temperature.
