Answer:
Another name of activation energy is "Needed energy" .
Explanation:
Activation energy can be imagined of as the measurement of the potential barrier (seldom described the energy barrier) distributing minima of the potential energy surface concerning the initial and ultimate thermodynamic phase. For a chemical reaction or distribution to advance at a reasonable rate, the specific temperature of the operation should be high satisfactory so that there subsists an apparent number of particles with translational energy equivalent to or higher than the activation energy. The word Activation Energy was founded in 1889 by the Swedish expert Svante Arrhenius.
Particles in solids are always vibrating (moving back and forth) in place. The vibrational motion of particles in solids is kinetic energy. Heat makes the particles in a solid vibrate faster, giving them more kinetic energy. ... When a sample of solid, liquid, or gas matter heats up, it expands.
Answer:
Explanation:
When you are in the laboratory and take a direct sniff of the chemicals you are using, you run the risk of damaging your mucous membranes or your lungs. When it is necessary to smell chemicals in the lab, the proper technique is to cup your hand above the container and waft the air toward your face.
Answer:
Denaturation causes loss of enzyme activity which is necessary for biochemical reaction.
Hence many biological process(respiration,digestion,excretion) won't work properly.
Explanation:
Enzymes : These are biological catalyst made of proteins.E.g Pepsin, tyrosine (human digestion)
Denaturation: loss of Quaternary ,tertiary and secondary structure of proteins and nucleic acid because of extreme conditions of temperature , pressure ,pH etc.
When denaturation occur enzymes loss their specific structure, so they can't carry out various life process (e.g respiration, digestion ,excretion).
Enzymes are involved in all biological reaction and work only at optimum temperature ,pH and pressure(human body condition ).
Yes, you can!
Hope this helped you, brainliest much needed and appreciated! Have a wonderful day!:)
