transformations, which occur within the ecosystem are considered in ecological energetics. The quantity of solar energy entering the earth's atmosphere is about 15.3 x 10 8 cals/m 2 /year (1 cal = 4.184 J). But the average amount of solar energy (per unit area per unit..

Transformer - For a given power requirement, one has the choice of the relative values of I r m s and E r m s . That is, for the product to be a constant, we can choose a relatively large current I and a relatively small potential difference v or just the reverse. In an electric power dis..

For a reaction to occur, reactant molecules must collide with each other. Only those collisions result in product formation which have energy equal or more than a certain minimum energy. This energy is called the threshold energy. This implies that ther..

The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics..

Example 11: The rate constants of reaction at 700 K and 760 K are 0.011M - 1 s - 1 and 0.105 M - 1 s - 1 respectively. What are the values of 'A' and 'E..

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 act..

Every organism has a tendency to increase its entropy, which is very much in accordance with the second law of thermodynamics. In order to maintain its organisation at the molecular, cellular and organismic levels, every organism is forced to obtain energy from its surroundings, so that ..
