The formula of the law of conservation of mass is as follows: ∂ρ/∂t +⛛(ρv) = 0. Where, ρ = density. t = time. v = velocity ⛛ = divergence. What is the Law of Constant Proportions?

The general formula for the conservation of energy in a closed system can be expressed as: ... The kinetic energy K of a particle with mass m and velocity v is given by: K=1/2mv 2.

The law of conservation of mass states that mass can neither be created nor destroyed. Interestingly, numerous ancient philosophers observed the knack for chemical and physical reactions to simply ...

How is matter different from mass? These and other questions about the deepest levels of physics, answered inside.

Show the animation Conservation of Mass in Physical and Chemical Changes. Explain that whether a process involves melting, dissolving, or a chemical reaction, all the atoms that were there before the ...
