Question

How is the temperature of a substance related to the kinetic energy of its molecules? Select all that apply.


A) As the kinetic energy of molecules increases, the temperature decreases.


B) As the kinetic energy of molecules increases, the temperature increases.


C) Temperature is a measure of the average electromagnetic energy of molecules in the substance.


D) Temperature is a measure of the average kinetic energy of molecules in the substance.

Answer 1

Answer:

Ke= 3/2×K×T T is temperature

Explanation:

A is not true because when kinetic energy has directly proportional to temperature

B true

C not true

D true

Answer 2

Kinetic energy is a source of power that an element or atom has as a result of its motion. Whenever work, that transfers the heat, is performed on an item by exerting a net force, the object accelerates & obtains kinetic energy.

• A temperature is proportional to its kinetic energy this indeed the energy that a substance has for a result of its molecule would be in motion.  
• As a substance absorbs heat, its molecules will move, raising that substance's kinetic energy.
• Temperatures seem to be a form of kinetic energy for atoms or molecules which is measured in degrees.
• Temperature goes up as the kinetic energy of atoms rises, & vice versa.

Therefore the final answer is "Option D".
