Why water has high boiling point and freezing point? So despite its small molecular weight, water has an incredibly big boiling point. This is because water requires more energy to break its hydrogen bonds before it can then begin to boil. The same concept is applied to freezing point as well, as seen in the […]

Why are graduated cylinders not accurate?
Why are graduated cylinders not accurate? Similar to cylinders, beakers are graduated with volume measurements. In that case, why is a graduated cylinder more accurate than a beaker? The volume marks on a beaker are only approximate values, and therefore only provide whole numbers. What is a graduated cylinder is used to measure? Liquid volume […]
What is the meaning of Brownian motion?
What is the meaning of Brownian motion? Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations.

How would your present weight change if Earth had twice the mass that it does now?
How would your present weight change if Earth had twice the mass that it does now? Twice the mass means twice the acceleration due to gravity which will increase acceleration by the factor of 2 thus the weight will be double the time. What will happen if the Earth is bigger than the current size? […]
Why is the charge of MgCl2 +2?
Why is the charge of MgCl2 +2? Explanation: Salts are electrically neutral. In magnesium chloride or calcium chloride or ferrous chloride, the charge on the metal centre is equally balanced by the chlorides. Cl− bears a single negative charge, and thus 2 equiv of chloride are required to give a salt. Why MgCl2 is soluble […]

How do you calculate spring constant?
How do you calculate spring constant? Ans: Spring constant can be calculated using Hooke’s Law. As per the Hooke’s Law, if spring is stretched, the force exerted is proportional to the increase in length from the equilibrium length. The formula to calculate the spring constant is as follows: k= -F/x, where k is the spring […]
