Interpretation: Comprehend the evidence that gases exert pressure.
Concept Introduction: Matter can exist in three possible
Solids are the substances with least intermolecular distance and strongest intermolecular forces whereas gases have largest intermolecular distance and weakest intermolecular forces. Liquids have intermediate value of intermolecular distance and intermolecular forces.
These states of matter can interconvert into each other and is called as interconversion of states of matter.
Answer to Problem 1TAI
- Compression of gases require high pressure from piston.
- Excess of filling burst the balloon that proves the excess of gas put pressure on the walls of balloon.
- When a tin can with a lid, half-filled with water is heated, then it bursts due to high pressure of water vapor.
Explanation of Solution
Gases particles have largest intermolecular distance between gaseous particles. Due to high kinetic energy, gaseous particles move freely and can escape from an open container. The presence of gases is difficult to predict yet not impossible. Due to random movement of gas particles, they exert pressure on the wall of container. The evidences in support of gas pressure are:
- Compression of gases require high pressure from piston.
- Excess of filling burst the balloon that proves the excess of gas put pressure on the walls of balloon.
- When a tin can with a lid, half-filled with water is heated, then it bursts due to high pressure of water vapor.

- It is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation.
