When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling. On average, only a fraction of the molecules in a liquid have enough heat energy to escape from the liquid.

1. (i)
2. Temperature- The rate of evaporation increases on increasing the temperature of the liquid.
3. (ii)
4. Surface area- The rate of evaporation increases on increasing the surface area because on increasing.
5. (iii)
6. Humidity of air- The amount of water vapor present in air is called humidity.

Increasing the temperature decreases the value of the equilibrium constant. Where the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant. The position of equilibrium also changes if you change the temperature.

From equation (1), permeability is inversely proportional to the viscosity of the fluid. It is known that viscosity varies inversely to the temperature. Hence, Permeability is directly related to temperature. Greater the temperature, higher will be the permeability.

With the rise in temperature, only viscosity of gases increases whereas force of surface tension decreases, elastic force decreases. Solid friction does not depend on temperature.

The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. If the container can expand, then the volume increases until the pressure returns to its original value.

The effect of temperature on the resistance of the conductor is directly proportional to each other. The increase in temperature of the conductor increases its resistance and makes it difficult to flow current through it.

Adding heat, however, does not always increase the temperature. For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. For instance, ice and water can exist together at the melting temperature.

In physics, the second law of thermodynamics says that heat flows naturally from an object at a higher temperature to an object at a lower temperature, and heat doesn’t flow in the opposite direction of its own accord.

In thermodynamics, heat and temperature are closely related concepts with precise definitions. Heat, qstart text, q, end text, is thermal energy transferred from a hotter system to a cooler system that are in contact. Temperature is a measure of the average kinetic energy of the atoms or molecules in the system.
