How are gases distinguishable from a solid or liquid at the molecular level?

Gas molecules are gonna be spread far apart. Liquid molecules are gonna be spread out but just not as far. Solid molecules are packed together.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

the answer is c.) there is a warm front in region a and a stationary front in region b.
