Basic Chemistry Quizzes Online & Trivia

The correct answer is B. Gases have no definite volume and the volume changes depending on its container. Gases are also compressible and the molecules of gases are more distant from each other compared to liquids’ and solids’ molecules. The kinetic energy of gases is not less than of a liquid. It moves in a straight line and is moving continuously and rapidly unless they hit each other or the walls of the container they are in. The speed varies depending on the size of the gas molecule. Heavier molecules move slower than lighter molecules. The kinetic energy and the temperature has a direct proportion. If there is a decrease in temperature the gas molecules’ gets slower and if there is an increase in temperature, the molecules of the gas move faster.

The subatomic particle found in the nucleus with a positive charge is the PROTON.

Atoms are particles that join up to form molecules which make up molecules. With the help of atoms, molecules are made and elements are formed. Atoms are the simplest "building blocks" of matter.
