The amount of order in an isolated system cannot increase; it may only stay the same or decrease. This expresses which of the following? Conservation of mass
The First Law of Thermodynamics
The second Law of Thermodynamics
Kinetic Theory
The definition of work
the definition of heat

Second law of thermodynamics.

Explanation:

Second law of thermodynamics states the entropy or order in an isolated system always increases. The isolated system evolve spontaneously toward thermal thermal equilibrium.

For example if a room is untidy and dirty,it will become messy over time and disorder. So when the room is cleaned, there won't be disorderliness and entropy will decrease.

i'm pretty sure it is letter c.) car

it is reliable if two scientists recorded it
