Which statements about a sample of gas containing molecules of different masses are true?
check all that apply.
__the rms speed depends only on temperature, and so all types of particles in the sample have the same rms speed.
__more-massive gas molecules in the sample have higher rms speed than less-massive ones.
__more-massive gas molecules in the sample have lower rms speed than less-massive ones.

More-massive gas molecules in the sample have lower rms speed than less-massive ones.

Explanation:

The rms speed is defined as the prediction that how fast the molecule travel at a given temperature.

Mathematically, rms speed can be written as,

Here, T is the temperature, M is the mass of gas molecule.

Now from this it is clearly seen that rms speed is inversely related with mass of the gas molecule.

Therefore, gas molecule which posses more mass in the sample have smaller rms speed than less-massive ones.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )
