We have observed in our daily life, that a jewellery of silver is looked like a gold jewellery but it is not that. Only a layer of Gold is electroplated over the silver jewellery. Have you ever thought how electroplated is carried out ?? In this article we will learn Read more…
If ( a / 2 ) = ( b / 3 ) = ( c / 4 ) = ( 2a – 3b + 4c ) / ( p ), then find p. Given : ( a / 2 ) = ( b / 3 ) = ( c / Read more…
If the product and sum of two quadratic surds is a rational number then surds are _______ surd. Answer : Complementary or conjugate . Explanation : Let us consider that { √a + b) } and { -√a + b) } are two quadratic surds, where ‘a’ and ‘b’ are Read more…
Write true or false : Only one circle can be drawn through three non-collinear points. Answer : True Explanatation : Through 3 non-collnear points, only one triangle can be drawn. Hence, only one circumcircle can be drawn. Therefore, the given statement is true.
Introduction : We have learned about the properties of the gas, Boyle’s Law, Charles’ Law, and Gay Lussaic’s Law. Through the kinetic theory of gas, we know that the gas molecules are of point mass and point volume. That means, with respect to the mass of the gas, the mass Read more…

You may find these on the following links : Properties of Gas, Class 10 Chemistry Boyle’s Law, Class – 10 Chemistry Charles’ Law, Class – 10 Chemistry Introduction : We Read more…
Introduction: As we know that the volume of the gas depends on the pressure as well as temperature. If the pressure of the gas is kept constant then what will be the interrelationship between the volume of the gas and its temperature? If the temperature is increased, then the average Read more…
Boyle’s Law The first modern chemist, Robert Boyle had proved and explained the two unique properties of any gas, expansibility, and compressibility. Statement : It states that ” the volume of a given mass of a particular gas is inversely proportional to its pressure at a constant temperature.” Explanation Let us Read more…
Properties of Gas In our surrounding, there are lots of things like furniture, ceiling fan, tube light, refrigerator, TV, mobile, water, oil, juice etc. We can touch, feel and see these substances. But we can neither see nor touch Air without which the life is meaningless. Have you ever thought Read more…
