Explain the three mechanisms of heat transfer in Earth’s atmosphere.
MariettaO [177]

Explanation:

There are three ways heat is transferred into and through the atmosphere.

radiation. conduction. convection.

Radiation

Radiation is the transfer of heat energy through space by electromagnetic radiation.If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms, while your other side remains unaffected by the heat. Although you are surrounded by air, the air has nothing to do with this transfer of heat. Heat lamps, that keep food warm, work in the same way.

Conduction

Welding iron is transferring heat by conduction

Conduction is the transfer of heat energy from one substance to another or within a substance. Have you ever left a metal spoon in a pot of soup being heated on a stove? After a short time, the handle of the spoon will become hot.This is due to transfer of heat energy from molecule to molecule or from atom to atom. Also, when objects are welded together, the metal becomes hot (the orange-red glow) by the transfer of heat from an arc.

Convection

convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid.

Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere

The nurse has administered a client's first scheduled dose of amoxicillin. what subsequent client report should prompt the nurse
Alexeev081 [22]

Amoxicillin is a broad-spectrum antibiotic widely used for certain bacterial infections in the ear, nose, throat, genitourinary tract, skin, lower respiratory tract, and its also used to treat gonnorhea. Amoxicillin is a fairly strong drug, and it can elicit an allergy to patients even to those who had used the drug before and did not experienced any untoward problems. If the patient had symptoms such as difficulty in breathing, itching, and untoward swelling or lump in the throat when receiving treatment with penicillins like amoxicillin, sulbactam, ampicillin, methicillin, or penicillin G, the nurse should discontinue giving amoxicillin and report to the doctor right away.
