Depends on the situation. It could be something like potential energy of a compressed or stretched spring.
The given statement "There is a set table of rate constants for the rate equation" is true.
Answer: Option A
<u>Explanation:</u>
The rate equation definitely has the need of set of table of rate constants. Rate constants are those which, in a reaction, describe whether it is fast, slow or moderate. And, if a set of rate constants is not available, one may take slow processes and have to wait a long time to predict the results.
And, if the reactions are fast, there is a chance of damage occurring to the surroundings. And since it is a constant, it is easier to determine the products of an intermediate steps, in a chemical reaction too.
Answer:
Law of conservation of mechanical energy.
Explanation:
During motion of a block sliding on the floor from the bottom of the ramp to the moment it stops , kinetic energy is converted into potential energy so that total energy remains constant . No other conversion is taking place , if we consider friction to be absent in the system . Potential energy and kinetic energy form part of mechanical energy . So we can say that mechanical energy is conserved . Hence , system is following law of conservation of mechanical energy.
The answer is convection. There are three main types of heat transfer: conduction, convection, and radiation. Among the three, convection is the one that involves heat transfer through a flowing material or medium. Conduction involves the direct contact between two surfaces at different temperatures, while radiation involves heat transfer through electromagnetic waves.
