The average kinetic energy of the molecules is proportional to the Kelvin temperature of the sample.

The average kinetic energy of the molecules is proportional to the Kelvin temperature of the sample.

Postulate 1 best describes this observation because when talking about how gas is compressible we talk about how tiny gas molecules are and how they float in empty spaces and are easily pressed together if wanted.

# data[].attributes.body
Postulate 2 best describes this observation because here the Helium molecules seems to never join together which shows that there are no attractive forces between gas molecules.

# data[].attributes.body
Postulate 3 best explains the observation above. The molecules moving fast and then expanding across the room shows how constant and rapidly gas molecules can move in a short amount of time. Fitting postulate 3.

# data[].attributes.body
Postulate 5 best explains the observation above. This is because the observation has to do with heat and temperature when it came to the gases. Which postulate 5 does talks about.

# data[].attributes.body
The situation above is best described by postulate 5 because this deals with kinetic energy and its relationship with temperature.

# data[].attributes.body
The situation above is best described by postulate 2 because the Helium molecules never join because there are no attractive forces.

# data[].attributes.body
The situation above is best described by postulate 3 because the fast and constant movement of the molecules made it detectable from across the room.

# data[].attributes.body
The situation above is best described by postulate 1 because the molecules are so small and empty that they are able to compress them if needed to. ( balloons)

# data[].attributes.body
Best explains postulate 1 because talks about the gases being compressible making it able to inflate balloons.

# data[].attributes.body
The situation best explains postulate 2 because Helium molecules don't have attractive forces making not able for the molecules to not join.

# data[].attributes.body
The situation above is best described by postulate 3 because molecules move so fast making the smell spread across the room.

# data[].attributes.body
The situation above is best described by postulate 5 because heating the balloon cause the gas to have kinetic energy.

# data[].attributes.body
the situation above is best described by postulate 3rd

# data[].attributes.body
the situation above is best described by postulate 5th

# data[].attributes.body
the situation above is best described by postulate 2nd

# data[].attributes.body
best described by postulate 1 because the molecules are so small and empty

postulate 2

postulate 3

postulate 5

# data[].attributes.body
Postulate number 1 because it says that they were able to inflate 30 large balloons from single little 5 L tanks an number one shows that its empty space

# data[].attributes.body
Number 2 There are no attractive forces between molecules because it says they never joined together

# data[].attributes.body
Postulate number 3 because it says that it the molecules moved so fast and that's what number 3 says

# data[].attributes.body
Postulate 5 because they blew up balloon so the energy of the molecules is proportional to the Kelvin temperature of the sample an it also heats up the container.
