Yes. If you get in your car on a hot summer day, is it hotter inside or outside the car? It's hotter inside the car because the gas is being trapped and can't go anywhere.

How does the changes in temperature and pressure affect the volume and the amount of gases?

In general chemistry we are taught the ideal gas equation of state PV=nRT. n is the number of moles of gas and R is the molar gas constant. This is an extremely important equation in the study of thermodynamics.


How a change in pressure or temperature will effect the volume of gases?

According to Boyle's Law, a decrease in pressure on a gas will cause its volume to increase, while an increase in pressure will result in a decrease in volume, assuming temperature remains constant. Conversely, Charles's Law states that increasing the temperature of a gas at constant pressure will cause its volume to expand, while lowering the temperature will lead to a reduction in volume. These relationships illustrate the inverse relationship between pressure and volume, and the direct relationship between temperature and volume in gases.


What properties do only gases have?

Gases have the property of indefinite shape and volume, as they expand to fill any container. They also have low density compared to liquids and solids. Gases can be compressed and expand easily when heated.


What happens to all gases many liquids and most solids when their temperature increases?

When the temperature of gases, many liquids, and most solids increases, their particles gain kinetic energy and move more vigorously. For gases, this often leads to an increase in pressure if the volume is constant, while liquids may expand slightly. Solids generally do not change their volume significantly, but they can become more malleable or change phase if the temperature is high enough. Overall, increased temperature typically results in expansion and changes in state or behavior.


Gases don't expand very much when heated?

This is incorrect. Gases expand significantly when heated because the increase in temperature causes the gas particles to move faster and spread out, resulting in an increase in volume or pressure. This relationship is described by Charles's Law, which states that the volume of a gas is directly proportional to its temperature.

Is temperature a factor in determining density?

In the case of gases yes. For a gas, the density is directly proportional to the pressure and inversely proportional to the temperature (absolute ie Kelvin). In other words the higher the temperature the lower the density. This is because gases expand with temperature. Liquids and solids do expand but only slightly so there is not much change in density for these.


What gases expand?

All gases can and will expand in the right conditions.

How do phases of matter change from one form to another with heat energy?

In general matter expands its temperature and volume with heat.This heat energy causes an increase of energy internal to the matter that expands its volume: solids melt to liquids, liquids expand to gases; and gases transform to plasma. At phase temperatures the matter changes form with no change in temperature;


Do gases keep the same volume?

Usually not. They can easily expand into a larger volume, or be compressed into a smaller volume.

Do all gases expand on heating?

Yes, gases generally expand when heated because the increase in temperature causes the gas particles to move faster and spread out, increasing the volume they occupy. This relationship is described by the ideal gas law, which states that pressure and volume are directly proportional at a constant temperature.


Why will all solids liquids and gases all expand and contract?

They are all subordinated to temperature variations, which make them contract or expand. This is a physical characteristic for almost all elements.

Can gases be heated?

Yes, gases can be heated. They try to expand if not contained, thus becoming less dense and causing convection currents. At a certain temperature some gases their "flash point" when they will burn or explode.
