What are some of the difficulties with measuring the volume of a gas? Select all that apply. (A) it could be soluble in liquid
(B) it can be difficult to contain.
(C) it varies depending on the container it is in
(D) it varies based on its mass

it is ---D because you can't measure gas and it's mass

HOPE THIS HELPS

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

nah.   i'm just sleepy.
