Why Vapour pressure does not depend on amount of liquid?
Why Vapour pressure does not depend on amount of liquid? It does not depend on the amount of liquid as long as at least a tiny amount of liquid is present in equilibrium with the vapor. The equilibrium vapor pressure does, however, depend very strongly on the temperature and the intermolecular forces present, as shown […]

Why do Ferris wheels rotate clockwise?
Why do Ferris wheels rotate clockwise? No matter from what direction you look, that stick is going to poke out of the wheel in the same direction, and that’s why the wheel turns anti-clockwise when viewed in one direction and clock-wise in the other direction. So that’s why the wheel turns clockwise or anticlockwise when […]
Why the test charge is positive?
Why the test charge is positive? Test charge is kept normally positive because as we all know that the flow of current or major charge carrier are electrons which are negatively charged. So to know what is the forces acting on the test charge due to parameters like current,magnetic field etc, we generally place a […]

What are the 5 functions of the musculoskeletal system? The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. What are two types of joints? What are the different types of joints? Ball-and-socket joints. Ball-and-socket joints, such as the shoulder and hip […]
How can we identify an isotope?
How can we identify an isotope? Isotopes are identified by their mass, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons). What is an isotope symbol? These differing […]
What are four problem solving strategies?
What are four problem solving strategies? Polya created his famous four-step process for problem solving, which is used all over to aid people in problem solving: Step 1: Understand the problem. Step 2: Devise a plan (translate). Step 3: Carry out the plan (solve). Step 4: Look back (check and interpret). What are 5 problem […]
