Question

Which one of the following phases of matter exhibits pressure?

• A. Solid
• B. Liquid
• C. Gas
• D. Plasma

Answer 1

Answer: (B), (C)

The correct options are
B Liquid
C Gas

$\bullet$ In the gaseous state, the particles move about randomly at high speed. Due to this random movement, the particles hit each other and also the walls of the container.
$\bullet$The pressure exerted by the gas is because of this force exerted by gas particles per unit area on the walls of the container.
$\bullet$ In the liquid state, the particles move about freely but with lesser as the particles of gas does.Due to this free movement, the particles of liquids hit each other and also the walls of the container.
