Question

As the temperature rises, the particles of matter move ______.
(A) Lower
(B) Stops moving
(C) Faster
(D) None of the above

Answer 1

Hint: Temperature is a physical quantity that helps to measure how hot or cold a substance is. Its unit is kelvin with symbol K. In order to solve this question, we need to understand the relation between temperature and kinetic energy. As temperature increases, KE also increases.

Complete Step by step solution
Energy is used to perform work and it is transferred from one object or substance to another object or substance. It is a quantitative property and it is conserved. The SI unit of energy is joule with symbol J. There are two forms of energy which are potential energy and kinetic energy. Potential energy is related to the position of an object and describes the potential of an object to be in motion. Kinetic energy is related to velocity of an object or the combined motion of particles of an object.
The formula of kinetic energy is as follows,
 $ KE = \dfrac{1}{2}m{v^2} $
The relation between kinetic energy and temperature is as follows,
 $ KE = \dfrac{3}{2}kT $
where KE is kinetic energy and T is temperature. Hence, we can say that temperature is directly proportional to the kinetic energy of particles that an object is formed of.
Therefore, if temperature increases, the particles of matter will move faster.
So, the correct answer is option C.

Note
Energy is a scalar quantity as it does not possess direction. There are other types of energy too which are as follows,
-Thermal energy
-Electrical energy
-Nuclear energy
