Gases are denser compared to other state of matter.

• TRUE

• FALSE

Gas expands when pressure is increased, and it will compress when pressure is reduced.

• TRUE

• FALSE

Temperature is measured with the help of manometer.

• TRUE

• FALSE

Gases can completely fill up the container in which they are placed due to their undefined shape and volume.

• TRUE

• FALSE
