Why do gases not have fixed shape?

टीपा लिहा

उत्तर

  1. Gases possess more intermolecular space and less forces of attraction.
  2. They can move freely at any direction.
  3. They have the property of filling the entire part of a container by taking the shape of the container.

So, gases do not have fixed shape.

When a gas jar containing colourless air is kept upside  down over a gas jar full of brown-coloured bromine vapour, then after some time, the brown colour of bromine vapour spreads into the upper gas jar making both the gas jars appear brown in colour. Which of the following conclusion obtained from these observations is incorrect?


A student placed a gas jar containing air in the upside down position over a gas jar full of red-brown bromine vapours. He observed that the red-brown colour spread upwards into the jar containing air. Based on this observation, the student concluded that it is only the bromine vapour which moves up and diffuses into air in the upper jar, the air from the upper jar does not move down by diffusion into the lower jar containing bromine vapours. Do you agree with this conclusion of the student? Give reason for your answer.
