    We get shock when we touch WET current system becoz water is a good conductor of electricity. But Pure water is not a good conductor of electricity becoz it contains very ions that's why pure water is a poor conductor of electricity whereas tap water is good conductor of electricity becoz it contains dissolved salts in it which readily ionizes or dissociates to ions Na+ and Cl- that can float through the water carrying charge and thus conducts electricity.

    The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass.

    The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.[1] The second law states that the rate of change of momentum of an object is directly proportional to the force applied, or, for an object with constant mass, that the net force on an object is equal to the mass of that object multiplied by the acceleration. The third law states that when one object exerts a force on a second object, that second object exerts a force that is equal in magnitude and opposite in direction on the first object.

    Definition • Mass is simply the measure of the amount of matter in a body. • Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity. Denotation • Mass is denoted by “M”. • Weight is denoted by “W”. Formula • Mass is always constant for a body and there are several formulas to calculate mass. • One way to calculate mass is: Mass = volume × density Weight is the measure of the gravitational force acting on a body. Weight can be calculated from the following formula: Weight = mass × acceleration due to gravity Quantity Type • Mass is a base quantity. Mass only has magnitude and so, it is a scalar quantity. • Weight is a derived quantity. Weight has both magnitude and direction (towards the centre of gravity) and so, it is a vector quantity. Unit of Measurement • The SI unit of mass is Kilogram (Kg). • The SI unit of weight is Newton(N). Gravitational Effect • Mass does not depend upon gravity and is constant everywhere. Mass can never be zero. • Weight is dependent on gravity and so, it varies from place to place. Weight can be zero where there is no gravity (like space). Measuring Instrument • Mass can be easily measured using any ordinary balance like beam balance, lever balance, pan balance, etc. • Weight can be measured by a spring balance or by using its formula.
