a. mixing water molecules contained in a beaker b. molecules in solid, liquid, and gas phases c. mixing two different molecules together d. molecules that have reached equilibrium

anonymous · Answer

I'm leaning towards D what about you

anonymous · Answer

i thought it would be b

anonymous · Answer

Hmm these just seem like weird answer choices to me lemme check

anonymous · Answer

ok

anonymous · Answer

Thermal Energy, also known as random or internal Kinetic Energy, due to the random motion of molecules in a system. Matter exists in three states: solid, liquid, or gas. When a given piece of matter undergoes a state change, thermal energy is either added or removed but the temperature remains constant. When a solid is melted, for example, thermal energy is what causes the bonds within the solid to break apart.

Yeah I guess it could be B

anonymous · Answer

Yeah I think it's B too now since thermal equilibrium is when two objects are at the same temperature
