There are 2 grams of H2 gas in a fixed volume container at 273 C. 16 grams of He gas isadded to the container and the temperature is raised to 819 C. So what is the ratio of finalpressure to initial pressure?

What effects does temperature have on pressure in a closed container?
Well the temperature of a gas in a container is directly proportional to the pressure of the gas & according to the kinetic theory of gases (viewing gases as made of particles which are in constant random motion) the change in pressure with respect to temperature is given by 2mvx where m is mass and vx the x-coordinate of the initial velocity of the particle. (looking at it as the molecules are colliding with the walls of the container along an axis, x in this case). this proportionality is the basis (implicitly) of Charles's law, Gay-Lussac's law and Boyle's law.
Is it possible for a balloon with an initial pressure of 200.0kPa to naturally expand four times its initial volume when the temperature remains constant and atmospheric pressure is 101.3kPa?

What happens to the pressure if the temperature in K is doubled?
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1
How long would it take to freeze a soda in dry-ice?
This depends on many factors: initial temperature of soda, mass and volume of soda and dry ice, the volume and geometry of the container, the temperature in the room etc.
What happens when two gases that do not react with each other are placed in the same container?
The volume of the container becomes the volume of the gas. The molecules in gases are in constant motion with direction, this causes the initial volume to expand to the volume of the container since the molecules eventually disperse to every region of the container.
Which container contains water with lower initial temperature?
You think probable to a Dewar container.
What is Charles law and boyles law?
BOYLES LAW The relationship between volume and pressure. Remember that the law assumes the temperature to be constant. or V1 = original volume V2 = new volume P1 = original pressure P2 = new pressure CHARLES LAW The relationship between temperature and volume. Remember that the law assumes that the pressure remains constant. V1 = original volume T1 = original absolute temperature V2 = new volume T2 = new absolute temperature P1 = Initial Pressure V1= Initial Volume T1= Initial Temperature P2= Final Pressure V2= Final Volume T2= Final Temperature IDEAL GAS LAW P1 = Initial Pressure V1= Initial Volume T1= Initial Temperature P2= Final Pressure V2= Final Volume T2= Final Temperature Answer BOYLES LAW The relationship between volume and pressure.

Describe the relationship between temperature and pressure?
The relationship between temperature and pressure is not named after a specific person, like Boyle's or Charles' Laws, but states that the relationship between the temperature and pressure of a gas (usually as observed in a rigid container) is direct. Therefore, as temperature increases, pressure does too.This is Gay-Lussac's law.The temperature and pressure of gasses are related. As the pressure increases the temperature also increases, and vice verse. As the pressure decreases the temperature gets colder.The ideal-gas law may be expressed as PV=nRT.Absolute temperature TNumber of moles (a measure of the number of molecules) nVolume VPressure PRydberg's constant R (some value that makes the numbers and the units work)Obviously, from the equation, you could half the temperature and keep the pressure the same, if, for example, you cut the volume in half. Or you could half the temperature and double the number of moles, and the pressure wouldn't change.
How to calculate final pressure when given initial pressure and initial temp and also final temp and know that it's a constant volume process from initial state?
You can calculate pressure and temperature for a constant volume process using the combined gas law.
What happens to the pressure if the temperature in K is doubled?
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1
What effect does temperature have on gas pressure in a closed container?
In a closed container, the gas pressure means the gas atom exerts on the wall of the container. If someone add volume of the gas to the container, it gives more chance for it to collide to the wall. on the other hand, if you heat the container(also the gas inside), it gives the gas atoms energy so it runs faster, it speeds up the chance of gas exert on the wall. it can also be explained as, in a period of time, more gas atoms have exerted to the wall of container.
What must the pressure and volume be if the pressure of its container is reduced to half its original size?
initial volume = V1 final volume = V2 initial pressure = P1 final pressure = P2 = (1/2)P1 P1V1 = P2V2 P1V1 = (1/2)P1V2 P1 cancels; V1 = (1/2)V2 V2 = 2V2.
If i have the initial and after temperature how would i be able to find the change in temperature?
You subtract the initial from the after, and the result is the change. If the initial temperature is 50º and the after is 70º, then the change is +20º.
