Question

Which of these statements are characteristic of matter in gaseous state?

A. Gases fill their containers completely.
B. Gases exert pressure.
C. Gases have mass.
D. The pressure of a gas is independent of the temperature.
E. Gases are compressible

Answer 1

Hello!

The statements that are characteristics of matter in the gaseous state are A, B, C, and E

All these statements describe gases. Statement D is the only one that doesn't describe a gas. The pressure of a gas depends on the temperature. This is described in the Ideal Gas Law (
`P*V=n*R*T`), and also in the Gay-Lussac's Law (
`(P1)/(T1) = (P2)/(T2) = (Pn)/(Tn)`). These Laws describes how the pressure of a gas changes with temperature.

Have a nice day!
