Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following can directly affect the movement of particles?
A
Heat
B
Temperature
C
Energy
D
Pressure
Explanation: 

Detailed explanation-1: -With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.

Detailed explanation-2: -An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume.

Detailed explanation-3: -As the temperature increases, the motion of the particles increases and results in higher kinetic energy.

Detailed explanation-4: -As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down.

Detailed explanation-5: -When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
