Answer: A. are relatively far apart
Explanation:
Compressbility is the ability of compound to reduce in size when pressure is applied.
Gaseous state is a state in which the particles are loosely arranged and have a lot of space between them. Thus molecules can be easily compressed.
They have highest kinetic energy. This state has indefinite volume as well as shape. The molecules in the gaseous state move faster with an increase in temperature as the kinetic energy increases with increase in temperature.
Thus most gases are easily compressed is that the molecules in a gas are in constant motion are relatively far apart.
Answer:
Ventilators are provided in the rooms at the top of the roofs because if the air inside the room gets hot, the hot air rises up and flows through these ventilators and thus cool air remains at bottom. Thus ventilators maintain conventional currents to keep the air fresh in the room.

Answer:
Explanation:
The total amount of atoms is found by multiplying Avogradro's Number and the number of moles:
Answer:
TRUE.
Explanation:
Mass Number is the sum of protons and neutrons present in the nucleus of an atom. Isotopy is a phenonmenon that occurs when atoms of same elements have different mass number (Number of neutrons).
2H isotope has 1 proton and 1 neutron.
3H isotope has 1 proton and 2 neutrons.
This meeans 2H isotope has fewer neutrons when compared to the 3H isotope. The correct option is TRUE.
