What is A sample of gas occupies 1.55L at STP What will the volume be if the pressure is increased to 50 ATM while the temperature remains constant?
A sample of gas occupies 1.55L at STP. What will the volume be if the pressure is increased to 50 atm while the temperature remains constant?
What will be the volume of a gas sample at 309 K if its volume at 215 K is 3.42 L.... assume the pressure is constant?
4,9 L
What will happen if the pressure on a sample of gas is raised three times and it's temperature is kept constant?
The volume become one third.
According to Charless law whenever the temperature of a gas at constant pressure decreases the volume increases.true or false?
Answer: No, this is not according to Charles law; however according to Boyles law this statement is correct ('true').Charles' law states: When the pressure on a sample of a gas is held constant, the Kelvin temperature and the volume will be directly related.Boyle's law describes how the pressure of a gas tends to decrease as the volume of a gas increases when temperature is held constant.
A sample of Xenon gas at 20degree Celsius and 0.570 ATM is cooled to a pressure of 0.100 ATM If the volume remains constant What is the final Celsius temperature?
It would be -221.7 deg C.

How does the addition of a constant and multiplication by a constant affect the arithmetic mean?
If you add the same constant to each element of a sample then the mean of this collection of values will be the mean of the original sample plus the constant. If you multiply each element of a sample by a constant then the mean of this collection of values will be the mean of the original sample multiplied by the constant.
When a sample of gas is heated at constant pressure the average kinetic energy of its molecules?
KEavg = 3/2RT Just need to know the temperature, T. ( in Kelvin ) R is a constant.
When a sample of gas is compressed from 6.0 L to 2.0 L at a constant temperature the pressure of the gas doubles?
Are you stating or asking ? If that's a statement, then it's an incorrect one. At constant temperature, the product of (pressure) x (volume) is constant. So, if the volume changed by a factor of 3, the pressure must also change by a factor of 3 ... the pressure must triple.
