🛑🛑 Important Scientific Laws and Theories
✅ Ohm's Law - It states that the current passing through a conductor between two points is directly proportional to the potential difference across the two points provided the physical state and temperature etc. of the conductor does not change.
✅ Pauli exclusion principle - It explains that no two electrons in the same atom or molecule can have the same set of quantum numbers.
🔹 Raman effect - It is the change in wavelength that occurs when light is scattered by the atoms or molecules in a transparent medium.
✅ Tyndall effect - The scattering of light by very small particles suspended in a gas or liquid.
✅ Boyles's Law - It states that temperature remaining constant, volume of a given mass of a gas varies inversely with the pressure of the gas. Thus,
PV = K (constant), where, P = Pressure and V = Volume.
✅ Charles's Law - It states that pressure remaining constant, the volume of a given mass of gas increases or decreases by 1/273 part of its volume at 0 degree celsius for each degree celsius rise or fall of its temperature.
✅ Coulomb's Law - It states that force of attraction or repulsion between two charges is proportional to the amount of charge on both charges and inversely proportional to the square of the distance between them.
✅ Heisenberg principle (uncertainty principle) - It is impossible to determine with accuracy both the position and the momentum of a particle such as electron simultaneously.
✅ Archimede's principle - It states that a body when wholly or partially immersed in a liquid, experiences an upward thrust which is equal to the weight of the liquid displaced by it. Thus, the body appears to lose a part of its weight. This loss in weight is equal to the weight of the liquid displaced by the body.
✅ Aufbau principle - It states that in an unexcited atom, electrons reside in the lowest energy orbitals available to them.
✅ Avogadro's Law - It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
✅ Brownian motion - It is a zigzag, irregular motion exhibited by small solid particles when suspended in a liquid or gas due to irregular bombardment by the liquid or gas molecules.
✅ Bernoulli's principle - It states that as the speed of a moving fluid, liquid or gas, increases, the pressure within the fluid decreases. The aerodynamic lift on the wing of an aeroplane is also explained in part by this principle.
✅ Gay-Lussac’s Law of combining volumes - Gases react together in volumes which bear simple whole number ratios to one another and also to the volumes of the products, if gaseous — all the volumes being measured under similar conditions of temperature and pressure.
✅Graham’s Law of Diffusion - It states that the rates of diffusion of gases are inversely proportional to the square roots of their densities under similar conditions of temperature and pressure.
✅ Kepler's Law - Each planet revolves round the Sun in an elliptical orbit with the Sun at one focus. The straight line joining the Sun and the planet sweeps out equal areas in equal intervals. The squares of the orbital periods of planets are proportional to the cubes of their mean distance from the Sun.
✅ Law of Floatation - For a body to float, the following conditions must be fulfilled: The weight of the body should be equal to the weight of the water displaced and the centre of gravity of the body and that of the liquid displaced should be in the same straight line.
✅ Law of conservation of energy - It states that energy can neither be created nor destroyed but it can be transformed from one form to another. Since energy cannot be created or destroyed, the amount of energy present in the universe is always remain constant.

✅ Structure of Fungi
➖ Almost all the fungi have a filamentous structure except the yeast cells.
➖ They can be either single-celled or multicellular organisms.
➖ Fungi consist of long thread-like structures known as hyphae. These hyphae together form a mesh-like structure called mycelium.
➖ Fungi possess a cell wall which is made up of chitin and polysaccharides.
➖ The cell wall comprises a protoplast, which is differentiated into other cell parts such as cell membrane, cytoplasm, cell organelles and nuclei.
➖ The nucleus is dense, clear, with chromatin threads. The nucleus is surrounded by a nuclear membrane.

🛑🛑How to Increase Problem Solving Speed For Jee And Neet
1. Proper Understanding Of Concepts and it's Application
- What is the concept all about?
-What does the concept say?
-Focus on significance of the concept
- What are the exceptions to this concept? -When, Where and How to apply this concept?
=> Follow the steps of derivation of the concept
=>Understand the formulae
=> TRY TO REPRODUCE CONCEPT IN YOUR WORDS
=> Practice questions on the concept (Start from the easy and gradually move to the difficult ones)
2. Visualisation Of Problem
Step 1. Draw the diagram as per the problem.
Step 2. Once the diagram is drawn, check the problem again to see if what is asked in the
question is clearly represented in the diagram.
Step 3. Check if the diagram makes sense. If the diagram looks absurd, there is some problem in your understanding of the question.
Step 4. Understand the question now by going through the diagram. If you find that this
3. Interplay Between Theory and Problem
Step 1. You Read Concept
Step 2. Solve Questions
Step 2.1=> Solve More Questions
Step 2.2 => Face Problems => Refers Solution and then STEP 2.1
