when cells are in a(n)
solution, they are maintaining homeostasis

When cells are in an isotonic solution, they are maintaining homeostasis.

Explanation:

"Homeostasis" is the process to maintain a stable and relatively constant internal environment. In addition to temperature it is maintained for many other factors too. "Isotonic solution" comprised of two solutions having the similar osmotic pressure across a semipermeable membrane.

Such solution maintain homeostasis of a cell via diffusion process. As in such solution the overall concentration on both sides of the membrane remains equal. The cell membrane command the movement regrading entrance and exit of anything in cell, the membrane control water and ion transport because of its phospholipid bilayer structure.

what is the statement?

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
