Kinetic theory explains the behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules. This is possible as the inter-atomic forces, which are short range forces that are important for solids and liquids, can be neglected for gases.

Explanation:
The theory for ideal gases makes the following assumptions
1. Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.
2. Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.
3. No molecular forces are at work. This means that there is no attraction or repulsion between the particles.
4. Gas pressure is due to the molecules colliding with the walls of the container. All of these collisions are perfectly elastic, meaning that there is no change in energy of either the particles or the wall upon collision. No energy is lost or gained from collisions.
5. The time it takes to collide is negligible compared with the time between collisions.
6. The kinetic energy of a gas is a measure of its Kelvin temperature. Individual gas molecules have different speeds, but the temperature and kinetic energy of the gas refer to the average of these speeds.
7. The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move.
8. All gases at a given temperature have the same average kinetic energy.
9. Lighter gas molecules move faster than heavier molecules.

Explanation:

Kinetic theory of gases:
- The kinetic theory of gases explains the behavior of gases based on the idea that gases consist of rapidly moving atoms or molecules.
- According to this theory, gas molecules are in constant random motion, colliding with each other and the walls of their container.
- The pressure of a gas is a result of these collisions between the molecules and the walls of the container.
- The temperature of a gas is related to the average kinetic energy of its molecules - the higher the temperature, the faster the molecules move.

Comparison with other states of matter:
- In contrast to gases, the kinetic theory of liquids explains their behavior based on the idea that liquids also consist of rapidly moving atoms or molecules.
- However, in liquids, the particles are closer together compared to gases, allowing them to slide past each other, giving liquids their ability to flow.
- The kinetic theory of solids explains their behavior based on the idea that solids consist of rapidly vibrating atoms or molecules.
- In solids, the particles are packed closely together in a fixed position, and they vibrate around their equilibrium positions.

Conclusion:
- The kinetic theory is a fundamental concept in understanding the behavior of different states of matter, providing insights into the movement and interactions of particles in gases, liquids, and solids.

Attempt All sub parts from each question.Molecular Perspective In water, there are two types of molecules. Some molecules are at the surface, called exterior molecules, and some molecules are inside, called interior molecules. The interior molecules are attracted to all the molecules around them. The exterior molecules are attracted to only the other surface molecules and to those below the surface. So that the energy state of the molecules on the interior is much lower than that of the molecules on the exterior. The molecules always try to maintain a lower energy state and hence the exterior molecules experience a downward force. This force is known as cohesive force. As a result they try to maintain a minimum surface area, thus allowing more molecules to have a lower energy state. Thus surface tension is created. The water molecules attract one another due to the water molecule’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen, cause water to "stick " together. This is why there is surface tension. Water has very high surface tension.
