1. It determines where the heat is getting absorbed. 2. We can see that after a few seconds of increase in temperature when it reaches a specific point the object turns to liquid from solid, that is the melting point. 3. In heating and cooling curves, latent heat represents the energy absorbed or released during a phase change of a substance. 4. A heating or cooling curve illustrates the concept of specific heat capacity by showing the slope of the curve during temperature changes. 5. In the study of thermodynamics, in the design of heating and cooling systems, and in the prediction of future temperature changes in the atmosphere or in a building.

Did with vinod uncle during the afternoon physics class.

1. Melting is where a solid turns to liquid, and freezing is where liquid turns to solid. 2. Sublimation is solid to gas and deposition is gas to solid. 3. The gas molecules slow down and come closer to becoming liquid. 4. The critical point on the phase diagram shows where the gas and liquid states of a liquid are identical and the substance is in one phase. 5. Phase diagrams help in understanding phase transitions by visually representing the different phases of a substance under varying temperature and pressure conditions. 6. Freezing, melting, condensation, etc. 7. Pressure affects the temperature leading to phase transition, like melting or vaporizing, etc.

1. Pure substances cannot be separated by physical means. 2. Diamond, gold, oxygen. 3. Pure substances have the potential to form predictable products. 4. It can increase the melting point as well as the boiling point. 5. Because the medical drugs with impurities will lead to fall of the company, since that drug will be useless.

No problem(I have to send this because if not it will show that you were the last person who updated in this post).

Malu This is a bit complex to understand, remember what santosh uncle said, just try to make it easy to understand in simple words.

I added Example

* An Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light. * Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings. * I will add example in the post

Time zones are regions of the Earth divided according to the time of day, based on the Earth's rotation and longitudinal position relative to the Prime Meridian. * Synchronization of Global Activities: Time zones help coordinate global business operations, meetings, and events. Without them, scheduling across different regions would be chaotic due to differing local times.

Time intervals are specific durations between two points in time and are crucial in scheduling and time management: * Efficient Task Allocation: By breaking down tasks into time intervals, you can allocate appropriate amounts of time for each task, helping to avoid overloading or underutilizing time slots. * Prioritization and Sequencing: Time intervals allow for prioritizing tasks based on urgency and importance. For example, setting shorter intervals for high-priority tasks ensures they are completed promptly. * Tracking Progress: Time intervals serve as benchmarks to track progress and ensure that tasks are being completed on schedule, allowing for adjustments if delays occur.

* Circulatory System: Transports oxygen, nutrients, hormones, and waste products; includes the heart, blood, and blood vessels. * Respiratory System: Facilitates gas exchange, supplying oxygen to the blood and removing carbon dioxide; includes the lungs, trachea, and bronchi. * Digestive System: Breaks down food, absorbs nutrients, and removes waste; includes the stomach, intestines, liver, and pancreas. * Nervous System: Controls and coordinates body activities through nerve impulses; includes the brain, spinal cord, and nerves. * Musculoskeletal System: Provides structure, support, and movement; includes bones, muscles, tendons, and ligaments. * Endocrine System: Regulates body functions through hormones; includes glands such as the thyroid, pituitary, and adrenal glands. * Urinary System: Removes waste from the blood, regulates water and electrolyte balance; includes kidneys, ureters, bladder, and urethra. * Immune System: Defends against pathogens and disease; includes lymph nodes, spleen, and white blood cells. * Reproductive System: Responsible for producing offspring; includes ovaries, testes, and associated structures.

The nervous system is the body's control center, responsible for regulating and coordinating activities through electrical signals and chemical messages.

* Filtration of Blood: Kidneys filter the blood to remove waste products, toxins, and excess substances like water and electrolytes. * Formation of Urine: The filtered waste is combined with water to form urine, which is then transported to the bladder via the ureters. * Regulation of Blood Pressure: By controlling the volume of blood (through the regulation of water and salt balance) and releasing hormones like renin, the kidneys help regulate blood pressure.

1. Respiratory System Function: The respiratory system, which includes the nose, trachea, lungs, and diaphragm, is responsible for gas exchange. When you inhale, oxygen from the air enters the lungs and diffuses into the alveoli, tiny air sacs surrounded by capillaries. 2. Gas Exchange: Oxygen from the alveoli diffuses into the blood within the capillaries, where it binds to hemoglobin in red blood cells. Simultaneously, carbon dioxide, a waste product from cellular metabolism, diffuses from the blood into the alveoli to be exhaled. 3. Circulatory System Function: The circulatory system, consisting of the heart, blood, and blood vessels, transports oxygenated blood from the lungs to the body. The heart pumps the oxygen-rich blood through arteries to tissues and organs. 4. Oxygen Delivery and Carbon Dioxide Removal: At the tissue level, oxygen diffuses from the blood into cells, where it is used for cellular respiration to produce energy. Carbon dioxide, a byproduct of this process, diffuses from the cells into the blood, which is then transported back to the lungs via veins to be exhaled.

1. Velocity = Displacement/time Acceleration = Change in velocity/time 2. Uniform acceleration refers to a constant acceleration, where the velocity of an object changes at a consistent rate over time. In other words, the object's speed or direction changes uniformly with time. 3. A velocity-time graph plots velocity on the vertical axis (y-axis) and time on the horizontal axis (x-axis). The acceleration of an object can be determined by finding the slope of the line on the velocity-time graph. 4. Force applied, mass of objects, friction etc. 5. An object moving in a circular path at a constant speed is a example of constant speed but changing velocity.

It depends on which direction it changes. if it changes direction while going down then its deceleration if it changes while going up its acceleration. or we can consider it as negative acceleration.

Avg speed of return = 33.33 km/h Avg speed for total journey = 50 km/h Velocity of onward journey = 55.55m/s to the front. Velocity of return journey = 18.51 m/s Velocity of total journey is zero because the displacement is zero.

1. Standard temperature and pressure( like in a specific area or atmosphere) 2. Am working on it

Normally its 2n^2 But when it comes to quantum physics you use quantum numbers like i have mentioned I still have to learn the quantum details
