Please help me on thid

ok first off you need to evidence of dry ice bc i remember she told us this too and g it right

Option (c) is the correct answer.

Explanation:

The ability of a substance to reduce in size or volume due to the increase in pressure is known as compressibility.

Also, according to ideal gas equation PV = nRT

where        P = pressure,                     V = Volume

                 n = number of moles,        R = gas constant

                 T = temperature

Since pressure is inversely proportional to volume. Hence, when pressure is increased then there will be decrease in volume. As a result, substance will be compressed.

Thus, we can conclude that the statement increasing the pressure on a gas decreases the volume, best describes the compressibility of a gas.
