Substance x transfers thermal energy to substance y through conduction. what is an accurate conclusion about the condition of both substances before conduction occurred? a. their molecules had the same amount of energy. b. the substances were the same temperature. c. substance x’s molecules were faster than substance y’s. d. substance x was cooler than substance y.

Option (C) is the correct order.

Explanation:

Substance X has thermal energy this means that there are more number of collisions and hence there will be maximum kinetic energy in its molecules.

In conduction heat flows from hotter body to colder body. Due to this substance X is able to transfer its thermal energy to substance Y.

But before conduction substance Y molecules did not have kinetic energy that is they were not in motion. So, molecules of substance Y only had potential energy that is they were at rest.

Thus, we can conclude that Substance X’s molecules were faster than substance Y’s is an accurate conclusion about the condition of both substances before conduction occurred.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
