<span>When an electromagnetic wave passes from space to matter, some part of the energy is absorbed by the matter and it increases its energy. The wave may reflect and some part may pass through the matter depending on the amount of energy they have. The amplitude of the wave decreases if some parts of it are reflected. </span>
Answer: protons and electrons
Explanation: In a neutral atom there are always equal numbers of protons and electrons.
Answer:
b. atomizes liquids into small solid particles
Explanation:
Spray drying -
It refers to the process of getting a dry powder from the liquid or the slurry ,with the help of hot gas , is referred to as spray drying .
The method is used in the field of pharmacy .
It is a type of atomizer or spray nozzle which helps to disperse the liquid into the controlled drop size spray .
Small solid particles are generated by this method .
Hence , from the given scenario of the question ,
The correct answer is b. atomizes liquids into small solid particles .
Well air pollution, lung cancer, global warming those are just a couple off if my head
Answer:
Thermoplastics have low melting temperature because of the week van der Waals bonds between their Long Chain Molecules
Polymer chains once synthesized they will remain stable in the environment because of the strong covalent bonds in the Long Chain Molecules
Explanation:
Thermoplastics are polymers that are easily melted and changed to another shape as many times as possible. They become molten when they are heated and solidify when cooled. Examples of thermoplastics include; polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamides, polyesters, and polyurethanes.
Polymers are organic materials that consists of a long chain of atoms held together by strong covalent bonds. Polymers constitute an important environmental concern because most polymers are non biodegradable and remain in the environment almost indefinitely.
