(b) It has comparatively more force of attraction than other gases​

Answer 1

Answer:

8.Humidity

9.Latent Heat

10.c

11.a

Answer 2

8. Humidity is not a matter.

9. Latent heat

10. Kinetic energy of the particles of all maters remains the same at a particular temperature.

11. It has weak forces of attraction. Explanation: CO2 is a gas. Therefore it will have low inter-molecular force of attraction.
