LAWS OF CHEMICAL
COMBINATION:
There are five laws of
chemical combination. Out of the five four deals with mass relationships while
the fifth one deals with the volume of reacting gases
1. LAW OF CONSERVATION
OF MASS:
This law was given by Antoine Lavoisier in
1789. It states that matter can neither be created nor be destroyed. In other
words, the total mass,i.e. the sum of mass of The Teaching Addictshttp://www.blogger.com/profile/11726779870041367224noreply@blogger.com0tag:blogger.com,1999:blog-2513473688731420158.post-81023849157270075532020-05-17T00:35:00.000+05:302020-05-17T00:38:26.486+05:30Physics: Some Mathematical tools - 2

Graph: It is the fictional representations of variation of one quantity with respect to another quantity. Shape of graph depends on the relation between two variables.
standard equation came from graph, its prove discuss later in math and link will be updated here.
y = mx where 'm' is slope of straight line.

●Negative, when taken in the clockwise direction.

Physical Classification of Matter:
Solid: Generally hard and rigid. In other words they have definite shape and definite volume. e.g. wood, table, rod etc.
Liquid: Generally takes shape of container, and they have definite volume but indefinite shape for e.g.The Teaching Addictshttp://www.blogger.com/profile/11726779870041367224noreply@blogger.com0tag:blogger.com,1999:blog-2513473688731420158.post-77056365324803020682020-04-26T21:52:00.001+05:302020-05-04T23:17:43.363+05:30Math : Topic 1. Set
Def. Set : '' Well defined Collections of Objects of particular kind''. Every object is called as element of set.
Sets are usually denoted by capital letters A, B, C, X, Y, Z, etc and the elements of a set are represented by small letters a, b, c, x, y, z,etc
e.g. V = {a, e, i, o, u.....}.If 'a' is an element of a set V, we say that “ 'a' belongs to V” the Greek symbol ∈ (epsilon) is used Unknownnoreply@blogger.com0
