WILL liquid co2 boil at room temperature?
CO2 will not be a liquid at room temperature, rather a gas. It is only a liquid when compressed. Actually IF contained at high pressure it will be a liquid at room temperature ...It requires a combination of both pressure and temperature. It is a liquid in CO2 fire extinguishers and when the pressure is released some of it boils, absorbing a large amount of heat energy, more of it is released from the nozzle as a solid which then sublimes to forma gas.
What do you observe when carbon dioxide gas is compressed to 70 atmospheric pressure?
The critical point of CO2 is 304.1K and 72.8 atm. If you're at 25C (298.15K), then CO2 will condense from gas to liquid. If you're above 31C (304.15K), then CO2 will condense from gas to a supercritical fluid. w
What would the temperature be inside of a C02 canister?
As long as the CO2 canister is not being emptied or filled, it will be at the same temperature as the room that it is in. If you actively emptying the canister, the temperature can go drop significantly because of the drop in pressure (see Ideal Gas Law), and it can get hot if you are filling it. In general, if an object is in thermal equilibrium with it's surroundings (true as long you are not changing its temperature or the temperature of the surroundings at a significant rate), the object will be the exact same temperature as the surroundings.
How does the temperature of gas change when it is compressed if the process is adiabatic?
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.
How is the temperature of CO2 determined if a thermometer is not present in the space in which the CO2 is collected?
If a thermometer is not present, you can estimate the temperature of CO2 by measuring the pressure inside the container where CO2 is collected. Using the ideal gas law, you can infer the temperature based on the pressure and volume of the gas. This assumes ideal gas behavior and neglects factors like non-ideal behavior or phase changes.
What happens to the temperature of a gas that is squeezed or compressed?
If you compress a gas the temperature increases

Does combustion of compressed natural gas pollute the air?
Yes. Mostly by the production of CO2.
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
Is nitrogen a compressed gas?
Nitrogen can exist as a compressed gas when placed under pressure in a container. At room temperature and normal atmospheric pressure, nitrogen is a colorless and odorless gas.

What weighs more an empty cylender or an cylender filled with compressed gas?
Your cylinder full of gas will weigh more, for it contains the mass of the gas. Some gases, when compressed, such as CO2, are in liquid form, and quite heavy.
How does the temperature of gas change when it is compressed if the process is adiabatic?
In an adiabatic process, the temperature is increased when it is compressed. There is an increase in internal kinetic energy, and because temperature is related to kinetic energy, it is also increased.

Which of the gas properties will change?
When a gas is compressed, its volume will decrease, its pressure will increase, and its temperature may increase.
How do you work out volume of compressed air?
To calculate the volume of compressed air, use the ideal gas law equation: PV = nRT, where P is the pressure of the compressed air, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature. This formula allows you to calculate the volume of the compressed air if you know the pressure, temperature, and quantity of air.
