Cellulat telephone operate with radio waves, a form of Electromagnetic waves
Answer:
Because with Gibbs free energy we can determine the spuriousity of reaction occurrence
Explanation:
Gibbs energy: is a thermodynamic potential that has units of energy that gives the condition of equilibrium and spontaneity for a chemical reaction (at constant pressure and temperature).
In the chemical thermodynamics of reactions and in non-cyclic processes, there are four useful quantities called "thermodynamic potentials". These are internal energy, enthalpy, Helmholtz free energy and Gibbs free energy.
While Entropy is a thermodynamic function that is a measure of the unusable part of the energy contained in a system or matter. It serves to measure the degree of disorder within a process and allows us to distinguish useful energy, which is what becomes entirely work, of useless, which is lost in the environment.
Answer: Hand tools are necessary for daily activities.
Explanation:
The hand tools are useful for day to day activities they aid in pouring substances, holding things, mixing substances, cleaning and for other purposes. In a chemical laboratory the hand tools like test tube holders can help in holding the chemicals. In a medical laboratory the forceps can be useful in holding and cutting the sections without causing any harm to the hands. Hand tools avoid the direct contact with the microorganisms in medical laboratory thus protect against infections. Hand tools aid in surgical operations and they help in avoiding direct contact with the blood vessels and organs preventing contamination and infections.
