The kinetic energy of the particles inside the balloon increase. This then expands the volume of the balloon.

When heat is added to the system, we increase the average kinetic energy of molecules making up that system. When we increase the temperature, molecules undergo more rapid collisions and therefore takes up more volume. Molecules in solid state of matter has the least kinetic energy.

Thermodynamic temperature (absolute temperature) is proportional to the averagekinetic energy of particles in "gases". An increase in temperature will increase theaverage kinetic energy of the particles of the gas and at the same time the particle'skinetic energy distribution gets broader.If pressure of the gas is kept constant, the gas expands (increases its volume).If the volume of the gas is kept constant, the gas pressure increases.

kinetic energy increases with the increase in temperature is a postulate in kinetic molecular theory of matter.if the pressure is kept constant when temperature decreases the kinetic energy of the molecules decreases resulting in decrease in the volume of the gas. Charle's Law state's that For a given mass of dry gas at constant pressure ,volume is directionally proportional to temperature ie V~T

No. Kinetic energy depends on SPEED and on MASS.

the volume of a gas will decrease at the kinetic energy of its particles decreases. (temperature is a measurement of kinetic energy). Lower kinetic energy means less particle collisions, and collisions of lesser force, leading to a lower volume. Bring the same balloon back inside from the cold, and the gas gains kinetic energy from the air indoors, and the balloon will "pump back up".

This requires one simple equation and then a further understanding of it. PV=nRT where P is pressure, V is volume, T is temperature, n is the number of molecule, R is some constant. From this we can easily see that an increase in temperature does in fact cause an increase in volume. To see why lets think about what temperature is. Temperature is a measure of average kinetic energy. So an increase in temperature increases the average kinetic energy. An increase in average kinetic energy means that average velocity must be increased (K.E = .5(mv^2)). More velocity means that the molecules in the balloon are flying faster, and since pressure is the same, the molecules spread out more, which must increase the volume.

You can only refer to the Kinetic Energy of the Gas Molecules in this manner, not the entire Volume of the Gas as an Object. To become a Gas Hydrogen must increase its Thermal Energy to the point that it goes from Liquid State to Gaseous State. This increase in Thermal Energy causes and increase in the Motion of the Hydrogen Molecules...increasing their Kinetic Energy. If cooled to Absolute Zero Temperature their KE goes to Zero and Molecular motion Stops.

In this case the volume increase, the density is lower.

In a container of constant volume, when the gas is heated, thermal energy is converted to kinetic energy. This increase in kinetic energy causes the gas particles to accelerate. This acceleration of particles causes the particles to crash into each other, increasing pressure. Because it is a closed container, the number of particles and the volume the particles take up remain the same.

The volume increase when the temperature increase.

With the rise in temperature of a solid, liquid, or gas, the particles gain kinetic energy allowing them to move faster and farther away from each other. This causes the the volume to increase.

An increase in thermal energy gives particles more kinetic energy, which causes them to vibrate more. As they vibrate more, the volume they take up increases.

If an object is heated, its atoms get more of kinetic energy, so they collide faster and thus volume is increased and desity is decreased.

The gas volume would usually stay the same I think but the pressure would decrease because there is less kinetic energy in the particles

You could decrease the volume available to the gas or by increasing the kinetic energy of the particles. Although, after initial increase in temperature, the gas loses its ability to expand on increase in temperature.

Possibly: P1V1 = P2V2 or: increase volume =&gt; lower pressure (thinking of the kinetic model)

Temperature and volume vary directly, so if temperature decreases, so does volume. Volume decreases because the measure of the average kinetic energy of the gas particles (temperature) is decreasing also. When that happens, a gas cannot expand, and will decrease.

The heat energy causes the molecules of H2O to move faster, imparting greater kinetic energy, and the temperature of the water increases.

Compressor surge only occur in centrifugal compressors. reciprocating compressor don't as they increase pressure by volume reduction, unlike centrifugal compressors where they increase pressure by converting kinetic energy to potential energy (pressure).

The volume increase - ib proportion to the cube of the linear increase.

No, that's not true. Look at the formula for kinetic energy. You need mass and speed.
