Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A temperature increase causes the particles ____
A
to slow down
B
to move faster
C
collide higher
D
in the right order
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: -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.
