Mass varies from place to place but weight does not.

Assertion: One mole of a substance always contain the same number of entities, no metter what the substance may be. Reason : One mole is the amount of a substance that contains as many particles or entities as there are atoms in exactly 12 g of the ""^12C isotope.

Movement of substances in bulk or in mass from one point to another as a result of pressure differences between the two points is called

Assertion: Mass is a property of one object alone, whereas weight results from the interaction of two objects. Reason: The weight of an object is proportional to its mass.

A rod of length 6m has a mass of 12 kg . It is hined at one end of the rod at a distance of 3m below the water surface. a.What must be the weight of a block that is attached to the other end of the rod so that 5 m of the rod's length is under water? b. Find the magnitude and direction of the force exerted by the hinge on the rod. The specific gravity of the material of rod is 0.5.

Assertion: The centre of gravity of a body coincides with its centre of mass only if the gravitational field does not vary form one part of the body to the other. Reason: Centre of gravity is independent of the gravitational field.

The quantity of heat required to change the unit mass of a solid substance, from solid-state to liquid state, while the temperature remains constant, is known as

Redox is a reaction in which both oxidation and reduction will take place simultaneously . It is obvious that if one substance gives electron there must be another substance to accept these electrons . In some reactions, same substance is reduced as well as oxidised, these reactions are termed as disproportionation reactions. For calculating equivalent mass in redox reaction change in oxidtaion number is realted to n-factor which is reciprocal of molar ratio. The equivalent weight of Cu_(2)S in the following reaction is Cu_(2)S + O_(2) to Cu^(+2) + SO_(3)

Assertion : If the radius of earth is decreased keeping its mass constant, effective value of g may increase or decrease at pole. Reason : Value of g on the surface of earth is given by g= (Gm)/(R^(2)) .
