QUESTION 7 If the temperature of a gas is increased and at the same time the volume of the gas is decreased, the pressure of the gas... O must decrease may increase or decrease or stay the same must stay the same may increase or decrease but cannot stay the same must increase

Which of the following statements regarding the density of gases is NOT correct? A)The density of a gas is inversely proportional to its molar mass. B) As the temperature goes up, the density of a gas does down. C) The gas phase of a substance has a much lower density than the liquid or solid phase. D) As volume increases, density decreases. E) If the pressure on a gas increases, its density increases.

Select all the statements that apply to Charles's law. Charles's law relates gas volume and temperature in Kelvin. The volume of as is proportional to its temperature in degrees Celsius or Kelvin. The volume of a gas decreases as temperature increases if the gas is kept at a constant pressure and fixed amount. ✔The volume of a gas increases as temperature increases if the gas is kept at constant pressure and fixed amount.

Which is ALWAYS held constant in Ideal Gas Law? * temperature O pressure O Rancal's O volume

To do first experiment, pump the gas pump to put gas into the chamber. Only use between 3 and 7 pumps. Increase the temperature to a number you like between 100 K and 500 K, using the fire/ice bucket on bottom. Do not change the chamber width for now, keep it at 10.0 nm (handle on left of chamber). Do not open the chamber to let gas molecules out (handle on top of chamber). Calculating moles using the Ideal Gas Law: PV = nRT, where R = 0.0821 Once you have everything how you like it, you will calculate how many moles of gas are in the chamber, by using the Ideal Gas Law. Recall the Ideal Gas Law requires specific units: atm, L, moles, and Kelvin. Pressure Is indicated by the circular instrument on the top right of the chamber. It is conveniently already in atmospheres. Volume - Determine the volume in nm^3 by multiplying the width, height, and depth of the chamber. Depth is always 1.00 nm and height is always 10.0 nm. Width is adjusted by you to 10.0 nm or 15.0 nm, depending on the…

What relationship would I expect to see between the pressure of a gas and the number of moles of  gas in the container and why

If the pressure of an ideal gas is increased while the temperature is held constant, which of the following could occur?     Question 1 options:   A)  The volume of the gas decreases while the moles of the gas decrease.     B)  The volume of the gas increases while the moles of the gas decrease.     C)  The volume of the gas decreases while the moles of the gas increase.     D)  The volume of the gas increase while the moles of the gas increase.

What happens to the volume of a gas when the temperature around the gas is increased?

Question 2

Graduated cylinder Test tubes QUESTION 20 In the experiment "Molar mass of volatile liquid", the pressure of the gas inside a flask was the same as atmosphere, and the temperature was identical to the boiling water temperature of water bath. How did you measure the volume of the gas inside the flask? Read the volume written on the flask. OFill the flask up to the brim with water and then transfer the water to a graduated cylinder. Measure the yolume of the liquid added to the flask before heating the sample. Measure the volume of the liquid that condenses in the flask after cooling the sample.
