Answer 1

Answer:

1)A

2)B

3)C

4) D

5) C

Explanation:

1)

System is an isolation of matter that has been chosen out of the universe and studied.

2)

Surroundings are everything outside the system that interacts with the matter within the system externally

3)

Thermal energy is associated with constant random motion of atoms and molecules associated with Temperature.

4)

Chemical energy is the energy stored in the bonds between the atoms and molecules. Breaking and making of these bonds lead to releasing and absorbing of energy to surroundings.

5)

Kinetic Energy is the energy associated with the motion of the particles.
