A tank filled with propane gas has a temperature of 275 K and a pressure of 25 ATM what happens to the temperature if the pressure is increased to 100 ATM?

The properties of an ideal gas are summed up in chemistry and physics in this neat equation: PV = kT
This is saying that (pressure) multipled by (Volume) = (the constant 'k') times (Temperature) .
Without getting into all the units and the details, in order to answer this question we only have to understand that when one side of the equation increases, the other side of the equation has to increase by the same multiplier.
Increasing the pressure from 25 ATM to 100 ATM, the left side of the equation (PV) is multiplied by 4. (The volume of the tank 'V' remains constant.) If propane behaves like an ideal gas or close to it, then the right side must also multiply by 4, and the absolute temperature becomes 4 times as great. If the tank is perfectly insulated and none of the heat escapes, then the gas in it rises in temperature from 275 K to 1100 K.

What is condensation temperature of propane?
Dew point is specified for a given concentration of water in atmosphere.
Is liquid petroleum gas a gas or a liquid?
Under normal temperature and atmospheric pressure conditions propane is gaseous. However, when the temperature is reduced to below −42.09 °C or when it is stored under high pressure (approx 177 psi), it takes the form of a liquid.
Reasons why the compound propane and carbon dioxide diffuse at the same rate at room temperature and pressure?
They have the same relative molecular mass
Why do propane gas bottles freeze when in use?
As you use the tank, the pressure inside goes down. As the pressure drops, the temperature also drops because of something called the Ideal Gas Law (see the "Ideal Gas Law" Related Questions linked the left of this answer). Ice forms on the tank because water moisture in the atmosphere is condensed on the cold tank and then frozen.
What is the psi on a 20 lb propane tank?
The pressure inside a propane tank depends on the ambient temperature of the tank and if Liquid Propane Gas (LPG) is present inside the tank. It has nothing to do with the size of the tank. A 20 lb tank that is not more than 80% full, in an 100 degree F environment, with LPG in it, will have approximately 172 PSIG, just as a 200 lb that is not more than 80% full, in an 100 degree F environment, with LPG in it, will have approximately 172 PSIG. Examples are: A tank with LPG (no more than 80% full) at 80 degree F with have 128 PSIG, 60 degree F with have 92 PSIG, 30 degree F with have 51 PSIG, and -20 degree F with have 11 PSIG. This explains the decrease in pressure as you use a large amount of propane from a tank quickly. The tank cools due to the venture effect which drops the temperature of the LPG. The drop in temperature results in a drop in pressure. When the tank warms up, as long as Liquid Propane Gas is still present the pressure will go up.

Is propane a gas?
Propane is a gas under normal conditions of pressure and temperature, but is normally storm under high pressure as a liquid.
What is the heat capacity of liquid propane?
It depends on the temperature and pressure.
How much pressure in a 30 lb propane tank?
You cannot use output pressure to tell how full a tank is. The pressure will remain constant until it's just about out of propane. You can use weight, if you know how much it weighs when empty, and when full - then it's just simple math.
What is pressure in LPG bottles?
The pressure in a propane bottle depends on the temperature. Propane boils at -42 oC at atmospheric pressure. Above this temperature the pressure in the bottle would be 0 psi. then it rises in a curve with the temperature. At Zero oC the pressure would be about 55 psi., at 10 oC it would be 78 psi. and at 43.3 oC it is 204 psi. Butane has a lower pressure/temperature relationship and that is why it is used where the bottle is indoors.
What is condensation temperature of propane?
Dew point is specified for a given concentration of water in atmosphere.
Is liquid petroleum gas a gas or a liquid?
Under normal temperature and atmospheric pressure conditions propane is gaseous. However, when the temperature is reduced to below −42.09 °C or when it is stored under high pressure (approx 177 psi), it takes the form of a liquid.
Is propane gasoline?
No. Propane is a gas under normal pressure and temperature conditions while gasoline is liquid. Gasoline consists of larger hydrocarbons than propane, chiefly octane and its isomers.
A gas barbecue grill uses propane gas The propane is stored in a rigid tank what happens to the pressure of the propane when the tank is left outside on a very hot summer day-?
Based on Charles's Law,when the temperature of a gas increases, so does the volume.
How can you convince people that propane is gas at room temperature?
Keep in mind that propane is a gas a room temperature only if the pressure is low - for instance, normal atmospheric pressure. Propane in a pressurized tank (such as a barbeque tank, or a fork lift truck fuel tank) is usually liquid even though it is at room temperature, and is then referred to as LPG or Liquified Propane Gas. It becomes a gas instantly upon being released from the tank or cylinder.
Is propane gas liquid or gas?
Propane is a gas a room temperature if it is not compressed. However, if it put in a canister under high enough pressure, it will be a liquid even at room temperature. Propane is a liquid below -44 degrees F or if its compressed. Grill bottles are only fillid 80% full with liquid. so you can use the propane gas on the top of the bottle.
Can cooking gas freeze?
Yes, but you would have to get the temperature right down. Propane will freeze at -188'C at atmospheric pressure.
Is PROPANE gas at room temperature?
true Boiling Point (°C): -42 Vapor Pressure at 21°C (kPa): 850 high pressure is used order to keep propane ina tank at a pressure of about 850 kPa, so will be liquide (70° F or 21° C)
