What is a vapor? O A. A substance that has a much higher melting point and boiling
point than other similar substances
O B. A substance that is always in the solid or liquid phase at room
temperature
C. A substance that is in the gas phase at a temperature at which it
would normally be a solid or liquid
O D. A substance that forms a gas, but only at very high temperatures

in physics, a vapor or vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature. A vapor is different from an aerosol.

Explanation:

c

Explanation:

because vapor refers to a gas- phase material that normally exits as a liquid or as a solid under a given set of conditions

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.

a electronegativity decreases beacuse the size of nucleus is bigger.
