Energy Flow
Energy is the capacity to do work. Solar energy is transformed into chemical energy by the process of photosynthesis, and is stored in plant tissue and then transformed into mechanical and heat forms during metabolic activitie..
Energy Flow
. Here again some of the energy is released as heat. When primary consumers are eaten by secondary consumers, the same process is repeated at every step of the food chain. Here it must be remembered, that energy released as heat is considered as energy lost. We can thus conclude..

Heat and Temperature
Heat and Temperature - Heat energy is present in every object above absolute zero. How do we know that heat is present in every object? Temperature of the body is an indication. (Absolute zero is the lowest temperature possible and is equal to -273 o C). Are heath..
Heat (Q)
Energy exchanged between the system and the surroundings when they are at different temperatures is commonly known as heat. If a system is at a higher temperature than the surroundings, then there is a flow of heat (or energy) from system to surroundings, causing a de..

Energy from the sun is captured by the green plants and passed on through the various trophic levels. The flow of energy is unidirectional i.e., non-cyclic. However, some energy is lost at every state in the atmospher..
Streamline flow
When an object moves through a fluid, there will be friction due to the resistance of the material medium. This resistance increases with the velocity of the body as in the case of a rocket and aeroplane. Hence to minimize this friction due to the resistance of the medium, the bodies of aeroplanes..
Practical Applications of Joule's Heating
This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe i..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Even though I don't feel good, the tutor helped me by totally helping me understand!
Tutor helped me on every question and help me when i was confused. Thank you Tutor Vista
