Answer:
See explanation
Explanation:
The degree of movement of molecules in each not the three different states of matter depends on the arrangement of the molecules.
In a solid, molecules are packed closely together and are held in fixed positions by strong intermolecular forces such that they can only vibrate or rotate about a fixed point.
In liquids, molecules are less closely packed hence they can flow around each other but possess only little kinetic energy. Intermolecular forces in liquids are much lesser than that of solids.
In gases, intermolecular forces are negligible and gas molecules move with a very high velocity and possess high kinetic energy. There are large spaces between gas molecules and they are always in motion.

Answer:</h3>
7.182K
<h3>
Explanation:</h3>
From the question we are given;
- Initial temperature, T1 = 275 K
- Final temperature, T2 = 395 K
- Initial volume, V1 = 5 L
We are required to calculate the final volume, V2
- Charles's law is the law that relates the volume of a gas and its temperature.
- It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
- Therefore;
To calculate, V2 we rearrange the formula;
Therefore, the ending volume will be 7.182K
