Question

what do u mean by chemistry , physics , nd biology........what is the differences....???

Answer 1

Physics - like math but embedded with scientific concepts to explain phenomena like for instance why does a pen drop when you don't grip it or why does it feel more tiring to climb upstairs than downstairs.. Gravity acts downwards, we are going against gravity so higher chemical potential energy is required.

Biology - study of plants and humans, animals, living organisms. Mechanisms that allow survival eg homeostasis , photosynthesis. Systems Eg immune, cardiovascular, endocrine, nervous

Chemistry - reactions when different chemicals are mixed. Atomic structure, chemical bonding, acids and bases, qualititaive analysis, oxides, salt, organic chemistry, separation techniques, Stoichiometry and mole concept, periodic table of elements, kinetic particle theory, redox reactions, chemical kinetics, etc.

Answer 2

chemisrty is a branch of science in which we talk about matter chemical equations elements etc and physics is branch of science in which we talk about force & motions time and speed etc and biology is a branch of science in which we talk about living things organisms and about living world hope u understand
