Introduction
Gas is one of the three states of matter - the other two being liquid and solid. A gas differs from a solid and a liquid in a number of ways. A gas fills entire space available to it and therefore it has no definite shape or volume. The molecules in a gas are in a continuous mot..
Introduction
The classification of matter into three different states, namely solid, liquid and gaseous state is termed as the physical classification of matter. Most properties of solid, liquid and gases that can be observed with our sense organs are called as 'macroscopic' properties..
Introduction
You have learnt that sound is a form of energy. It is produced by vibrations. Sound waves are longitudinal waves. They are also elastic waves hence they need a material medium for their transmission. They can not be transmitted in vacuum. They travel in solids, liquids and gases. Their ve..
Introduction
Oscillatory motion, or periodic motion, is the most common type of motion. Heartbeat of animals, the seasons of the year, the swinging of the pendulum of a clock and the vibrations of atoms in solids are periodic in nature. Two types of motion that are closely associated with oscillatory ..
Introduction
Surface chemistry is the study of processes that occur at the interface of two bulk phases. The bulk phases can be of the type solid-gas, solid-liquid, liquid-gas and liquid-liquid. There is no interface between gases because of their complete miscibility. The bulk phase can be ..
Introduction
In 1926, an American rocket engineer Robert Goddard, built and tested the first rocket which used liquid fuels instead of solid gun powder. During the Second World War powerful liquid fuel rockets were built by Germans to carry explosives. Later, Americans started building their own rocke..
Behaviour of Solids
Introduction - A spider web is stronger than steel of the same thickness. Its elastic limit is greater than that of steel. A force is a push or pull exerted by one object or body on another. It may cause a body at rest to move or one in motion, to change its speed or direction. It may als..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
