is matter around us pure?
Can liquids really be compressed (as the above video says?) Because i tried an experiment using a plastic syringe without a needle,filled with water. i pressed it on my finger- giving it no space to escape.The plunger of the syringe did not move an inch.Faulty video???
plz explain me about cohesive and adhesive force
how to find the percentage composition of a substance????also plzz show an example
when we heat up the water with the rod by electricity why does it not break the water molecules in the process of electrolysis ?
Which of the following statementsare not true?
1) Most of the space in an atom is empty. 2)The total number of electrons and protons in an atom is always equal. 3)The total number of electrons in any energy level can be calculated by the formula 2n2.
State with reasons.
142 g of sodium sulphate (Na2SO4) has
12.0441023sodium ions
Is light also matter???
What is rhe difference between cathode rays and anode rays???
Generally, the states of matter consist of solids, liquids and gases. But isn't there another state called plasma? Where can this state of matter be found in space as well on Earth?
can u explain what is meant by latent heat again , i did not understand it ??????????????
what are properties of cathode rays
name the 5 states of matter where it is used
Is Melting point the temperature ABOVE OR AT which a solid changes its state to liquid?...(as during change of state, there is no change in the temperature as the heat energy is utilized in breaking the potential energy system of the substance).
