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…
WBBSE – 2019 Solution : Ratio of the principal = Ratio of profit share = 1 / 2 : 1 / 3 = ( 6/2 ) : ( 6/3 ) = 3 : 2 The required answer is ( b ) 3 : 2
WBBSE – 2019 Solution: Given that p + q = √13 Squaring both sides, we get ( p + q )2 = 13 ( p – q )2 + 4 pq = 13 ( √ 5 )2 + 4pq = 13 5 + 4pq = 13 4pq = 13 – Read more…
