The matter is everything around you. Atoms and compounds are all made of minimal parts of matter. Those atoms go on to build the things you see and touch every day. The matter is defined as anything that has mass and takes up space (it has volume). Words such as big, little, long, or short are used to describe volumes. Matter can exist in one of three primary states: solid, liquid, or gas. Particles in a: gas are well separated with no regular arrangement, liquid are close together with no regular arrangement, and solid are tightly packed, usually in a regular pattern. This chapter contains several fundamental concepts related to intermolecular forces and how they affect the physical state of a substance. It also deals with several other essential concepts associated with the liquid and gaseous states of matter. It is the reason why “states of matter” is regarded by many as one of the most important. The topics covered in this chapter include intermolecular forces and thermal energy, gas laws, the ideal gas equation, the kinetic theory of gases, the deviation of gases from ideal behaviour, liquefaction of gases, and the liquid state. Class 11 Chemistry (chapter 5) provided on this page deal with the following types of questions:
Numerical problems based on Boyle’s law, Charles’s law, Gay-Lusscac’s law, and Avogadro’s law.
Numerical problems on calculating partial pressure.
Questions on critical temperature and pressure.
Questions on Van der Waals forces and other types of intermolecular forces.
