GENERAL KNOWLEDGE

Detailed explanation-1: -With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement.

Detailed explanation-2: -The faster the molecules of a substance move, the higher the kinetic energy, and the higher the temperature. The slower the molecules move, the lower the kinetic energy, and the lower the temperature.

Detailed explanation-3: -Molecules move faster when temperature increases and move slower when temperature decreases. The increased molecular movement causes solids, liquids, and gases to expand when heated. The opposite holds true when temperatures decrease.

Detailed explanation-4: -As the temperature increases, the motion of the particles increases and results in higher kinetic energy.

Detailed explanation-5: -Because the speed of a particle is proportional to the square root of its kinetic energy, increasing the temperature will also increase the number of collisions between molecules per unit time.
