A. I think I’m that’s what it is
Density is the ratio of the substance's mass to volume. To know the effects of temperature on the density of the liquid, we must look at the mass and volume dependence. Mass is always constant, so it is not affected by temperature. For volume, generally, the molecules of the liquid occupy a greater space when heated because of the rapid collisions of the liquid molecules. Thus, as temperature increases, the volume of liquid also increases, although slightly only. That means that density would decrease.
Answer: C - Organisms return water to the environment after they use it.
Explanation: The amount of water on earth will always remain the same. Water goes in and out of all organisms. It is not possible to be more or less.
I think the correct answer is b
