The pressure of a sample of helium in a 1.00 L container is 0.988 ATM What is the new pressure if the sample is placed in a 4.40 L container?
The pressure of the helium will decrease when placed in the larger container, following Boyle's Law. Using the formula P1V1 = P2V2, we can calculate the new pressure. So, (0.988 ATM)(1.00 L) = P2(4.40 L), which gives P2 = 0.225 ATM.
What happens to the size of a particle in a sample when liquid is heated in a closed container until it change to Gas?
evaporate
Would a sample of gas in a closed container in space exert pressure on the sides of the container if the gas was kept at standard temperature and pressure?
Even if the pressure inside a container is equal to the pressure outside a container, there is still pressure. It's like pushing a friend one way while he pushes you back. Neither of you may be moving, but you're still pushing. The sample of gas would exert exactly one atmosphere of pressure (or 100 kPa) on the container. The question then becomes whether the container can withstand that pressure.
A sample of water was found to boil at 15C in a closed container What must have been true for this to occur?
The pressure must have been extremely low in the container.
Do gases exert pressure?
Yes. Any sample of gas in a closed container will exert pressure on the container, as long as the temperature of the gas is above absolute zero. You can force the gas into a smaller volume by shrinking the container, but that action raises the temperature and pressure of the gas.
When a sample of gas is heated what happens to the motion of the particles?
When a gas sample is heated, the particles move faster and collide more frequently with each other and the walls of the container. This increased movement and collisions lead to an increase in the pressure and volume of the gas.

A sample of water was found to boil at 105C in a closed container What must have been true for this to occur?
The pressure must have been extremely low in the container.
A sample of water vapor was found to condense at 105C in a closed container What must have been true for this to occur?
The pressure must have been higher than 1 ATM in the container.
When a sample of gas is cooled in a closed container the pressure inside the container?
decreases as the temperature of the gas decreases. This relationship is explained by the ideal gas law, which states that pressure is inversely proportional to temperature when volume and amount of gas are constant.
Do gases exert pressure?
Yes. Any sample of gas in a closed container will exert pressure on the container, as long as the temperature of the gas is above absolute zero. You can force the gas into a smaller volume by shrinking the container, but that action raises the temperature and pressure of the gas.
What is measured by the pulling of gravity on a sample of matter?
The gravitational forces in each direction between the Earth and a sample of matterare equal. The force exerted on the sample by the Earth is what we call the "weight"of the sample. The force exerted by the sample on the Earth is the one that nobodyever mentions, but it's also equal to the weight of the sample. In other words, theweight of the sample on Earth is equal to the weight of the Earth on the sample.
What is the pressure in atmospheres exerted by a 0.500 mol sample of oxygen gas in a 10.0 L container at 298 K?
To find the pressure exerted by the gas, we can use the ideal gas law, ( PV = nRT ). Here, ( n = 0.500 ) mol, ( R = 0.0821 , \text{L} \cdot \text{atm} / (\text{mol} \cdot \text{K}) ), and ( T = 298 , \text{K} ). Plugging in the values, we get ( P = \frac{nRT}{V} = \frac{0.500 \times 0.0821 \times 298}{10.0} \approx 1.22 ) atm.
