Why does the mass of a gas not change when it is compressed?
Non compressed gas has the gas particles spread out more. But when compressed packed more tightly therefore taking up less room but yet still has the same amount of atoms. So you still have the same weight but just that the particles are packed more tightly.
When a gas is compressed in a cylinder what does the distance between the gas molecules do?
The compression will result in a lowering in the average distance between molecules of the gas. Imagine that the cylinder is like that in an internal combustion engine, with a piston inside the cylinder. The compression is accomplished by pressing the gas into a reduced volume. The number of gas molecules remains the same. With the same number of molecules in a reduced volume, the gas molecules are pressed more closely together, lowering the average distance between the gas molecules.
What happens when a gas is compressed in a closed container?
When a gas is compressed in a closed container, the pressure of the gas increases because the volume it occupies decreases. This increase in pressure can lead to the gas molecules being closer together, resulting in an increase in temperature.
A gas sample is held at constant temperature. What happens to the pressure of the sample if the volume is doubled and the number of molecules is doubled?
If the volume is doubled and the number of molecules is doubled while the temperature is held constant, the pressure of the gas sample will remain the same. This is because both the volume and the number of molecules increased by the same factor, resulting in no net change in pressure according to the ideal gas law.
How do the molecules of a gas compare to molecules of a liquid?
Molecules in a gas are far apart and move freely in all directions, while molecules in a liquid are closer together but still able to move past each other. Gas molecules have higher kinetic energy compared to liquid molecules, which allows them to spread out more easily.
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
Which gas can be compressed and expanded?
An ideal gas can be both compressed and expanded. In regards to ideal gas, when the gas is expanded or compressed, the molecules will remain the same. In order for the count of molecules to change, gas would need to be added. The molecule count can also change if gas escapes.

What happens the density of a gas as it is compressed?
The atoms or molecules of a gas will increase in thermal energy when the gas is compressed. The kinetic energy of those atoms or molecules will increase as they are forced closer together in compression, and the temperature of the gas will increase.
What happens to the temperature of a gas that is squeezed or compressed?
If you compress a gas the temperature increases
Does the vloume of a gas change when its compressed?
Yes, when a gas is compressed it could form into a solid or liquid substance.
How is pressure affected when a gas is compressed?
When a gas is compressed, its volume decreases while the number of gas molecules remains the same. This leads to the gas particles being more concentrated in a smaller space, resulting in an increase in pressure according to the ideal gas law, which states that pressure is inversely proportional to volume.
Why can gas move very fast and be compressed?
Gas molecules are very far apart compared to liquids and solids. This allows gas molecules to move freely and quickly, leading to high speeds. Gas can also be compressed because the molecules have more space between them, allowing for closer packing under pressure.
Why can gases be compressed more than liquids and liquids more than solids?
Gases have the space between their molecules, and so can be compressed the most. Next is liquid which has more space between the molecules than a solid, but not as much space as in a gas. So, it an be compressed also, but not as much as can a gas. And finally, a solid does not have much space between molecules and thus cannot be compressed too much.
Why can you compress a gas but not liquid or a solid?
The question is based on the misconception that liquids and solids cannot be compressed: they can. The molecules of gas are further apart allowing them to be compressed more easily.
Why does the volume of a gas decrease when pressure increases?
As pressure increases, the molecules of the gas are compressed, reducing the amount of space between molecules, which results in a decreased volume.
