# Questions tagged [gas]

This tag is for questions relating to "gas", one of the four fundamental states of matter (the others being solid, liquid, and plasma). Gases follow certain laws known as the gas laws. These laws tell us about the behavior of gases i.e., the values and relations of temperature, pressure and volume etc.

### Would gas inside of non-compressible material be affected by pressure in the deep ocean?

I was thinking about the pressure of the deep ocean and was curious if gasses inside of a non-compressible container would experience the extreme pressures associated with great depth. I'm sort of ...

### Pressure exerted by CO2 gas vs N2O in 0.5l container

What pressure is exerted by 8g (eight grams) of N2O gas on the walls of a container that has about 0.5l (half of liter) of volume? Will the pressure be the same in case of 8g of CO2 gas? Background: ...

### What is the counter-force to suction force?

I've been thinking about air pressure and vacuums recently and a (for me at least) interesting question came to mind: If there is an area with lower pressure than the surrounding air, the air ...

### Is there any problem in this task? (molecular formula of a gas inside a cylinder) [closed]

I got this task: A cylinder of volume V₁ = 2 L filled with gas of mass m = 7.48 g at T = 10 °C and under pressure P₁ = 2 bar Calculate the amount of gas substance in the cylinder. Infer the molecular ...

### How do turbine engines improve compression ratio?

As I have learnt from the Venturi tube that Pressure is inversely proportional to velocity. When a general aircraft is flying at say Mach 0.8 and at the same time there is a pressure decrease with ...

### What is meant by “is driven by collisions between its atoms and molecules”?" in NASA's statement?

"The behavior of a dense atmosphere is driven by collisions between its atoms and molecules." says https://www.nasa.gov/content/goddard/ladee-lunar-neon. It seems to me that a gas's behavior ...
