SSC MTS EXAM

Detailed explanation-1: -In a gas, particles have vibrational, rotational, and translational motion, allowing them to “bounce” off of one another. Particles in a gas state move much faster than a liquid.

Detailed explanation-2: -gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place.

Detailed explanation-3: -Attractive forces don’t get weaker when a substance moves from the solid to the liquid to the gas state, rather the kinetic energy of the particles increases (implying faster motion), allowing them to overcome the attractive forces.

Detailed explanation-4: -Gas particles are in constant rapid motion in random directions. Collisions between gas particles and between particles and the container walls are elastic collisions. There are no forces of attraction or repulsion between gas particles.
