Suppose you have two identical 1.0 L sealed containers. Both containers are kept at exactly 25oC. One vessel contains only neon gas at 1.5 atm, and the other contains only xenon gas at 2.5 atm. A) Is the average kinetic energy possessed by the neon atoms greater than, equal to, or less than that of the xenon atoms? Explain.

B) What variable must be changed in order to decrease the average kinetic energy of the xenon atoms?

C) Does the vessel with the xenon gas contain more, fewer, or the same number of gas particles as the vessel of neon gas? Explain.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
