What is the unique quality of gases in relationship to volume?
A gas will expand to fill up any volume available to it. Think of rigid containers that will not change shape or volume. If you have 10 completely empty containers that can be connected. Inside each is a vacuum. Place some gas in the first container. It completely fills the container and creates some pressure. Connect a second container and some of the gas leaves the first container, but not all of the gas. The gas will completely fill both containers, but creating less pressure. Continue connecting containers, and the same appens every time. The gas completely fills every container that is connected and the pressure 'adjusts' on its own to reach a new equilibrium pressure.
How do you observe gases?
Gases can be observed by their physical properties, such as expansion to fill their containers, diffusion, and pressure changes. Techniques like using gas syringes or manometers can help measure volume and pressure, while experiments involving color changes or reactions with other substances can indicate the presence of specific gases. Additionally, spectroscopic methods can identify gases based on their absorption or emission spectra.
What characteristic of a gas is the ability to be easily squeezed and compacted into smaller containers?
The characteristic of a gas that allows it to be easily squeezed and compacted into smaller containers is known as compressibility. Gases have widely spaced particles and minimal intermolecular forces, which enable them to be compressed into smaller volumes when pressure is applied. This property distinguishes gases from liquids and solids, which have fixed shapes and volumes. As a result, gases can expand to fill the available space in a container.
How are cryogenic gases transported?
Cryogenic gases are transported in specialized containers called cryogenic tanks that are designed to keep the gases at extremely low temperatures. These tanks are well-insulated and generally made of stainless steel or other strong materials to prevent heat from entering. Cryogenic gases are either transported in liquid form in these tanks or as compressed gases in high-pressure cylinders.

Which state changes produce a vapor pressure?
Conversion of liquid to gases state
What happens inside a can of spoiled food as gas produced?
The pressure increases (apex)
Variation of pressure in liquids and gases in everyday phenomena-?
Pressure variation in liquids can be observed when squeezing a water bottle, which increases the pressure inside. In gases, pressure variation can be seen in weather systems where high pressure brings clear skies and low pressure brings storms, also in inflating a balloon causes an increase in pressure inside.
How does the can crushing lab experiment demonstrate the principles of pressure and volume in gases?
The can crushing lab experiment demonstrates the principles of pressure and volume in gases by showing how changes in pressure can affect the volume of a gas. When the can is heated and then quickly cooled, the pressure inside the can decreases rapidly, causing the volume of the gas inside to decrease as well. This demonstrates the inverse relationship between pressure and volume in gases, known as Boyle's Law.

What is the air inside a balloon?
The air inside a balloon is a mixture of gases, typically consisting of nitrogen, oxygen, carbon dioxide, and trace amounts of other gases. When the balloon is inflated, the pressure of the air inside the balloon is higher than the atmospheric pressure outside, causing the balloon to expand and float.
Can you twist balloons with gases in them because gases have no fixed shape?
yes because all air is formable and moldable depending on the pressure inside of the balloon if there is to much pressure it will pop im in 6th grade
What changes shape and volume when you change containers?
Gases do that.
Why can gases be compressed easily?
they take the form of their containers
What instrument measures gases in closed containers?
On 2 aspects, 1. A pressure sensor, can link to amount of gas formed, and a GC autosampler can work for qualitation, or quantitation
