Answer:
Ideal gas explains the property of gas that has no inter-molecular attractions irrespective of temperature and pressure.
<u>Explanation:</u>
- Ideal gases assumes that the gases would experience no inter-molecular attraction and collision with other gases.
- These gases are perfectly exhibiting elastic collision in nature.
- The particle of gases moves slowly at lower temperature and the gases would become close when they exhibit high pressure.
- The "closeness of the gas-particle" and "low-speed characteristics" are the important observations noted.
- The inter-molecular forces deviate the property of gases from ideal gas behavior.
Gold is a mixture Becasue it contains more than one element
Answer:
D. The particles move up and down without changing their position
Explanation:
These are gases. They are typically known for their randomness and no fixed arrangement of their atoms.
Gases generally assume the volumes of the containers they fill. They spread easily and readily to fill the volume where they occupy. Also, gases are readily compressible as they lack intermolecular attraction between their molecules.
