Answer:
lightning conductors/rods protect buildings by intercepting lightning strikes that may hit these structures.
Air conditioners pass air over cold coils known as evaporator pipes
Explanation:
Lightning rods are made of highly conductive metal, and offer a path of least resistance for any lightning strikes and are connected to longer wires that ground the charge.
air conditioners use a chemical compound called a refrigerant. the most common refrigerant used is r-134a also know as 1,1,1,2-Tetrafluoroethane. cooling systems use the low boiling points of these refrigerants to constantly cool and compress the chemical to continually move heat from the inside of the system to an external area.
Answer:
The term used when one objects heat transfers to another would be known as: Convection.
Explanation:
Convection: <em>"the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat."</em>
The article I skimmed over explains, <em>"The outside surface of the cup is obviously hot or warm to the touch. Heat is not carried away fast enough from the cup to make the temperature of the outside surface of the cup equal to room temperature. Clearly, the cooling of the hot water in the cup involves conduction of heat through the cup followed by convection of the hot air associated with the outside surface of the cup away from the surface of the cup."</em>
In short, when a warm or cold liquid in a glass is set onto a table (the table is room temperature), then the temperature of that liquid will transfer into the table, causing the liquid to be room temperature after a certain time.
I hope this makes sense to you! Have a great rest of your night!
Its actually A. I did the same question and A was the correct answer.
The pressure reading for the butane tank is higher than that for the propane tank is False.
The pressure readings will change when more liquid is added to the tanks is False.
If the tanks are placed outside and the sun warms each tank to 46 , the pressure readings will be higher than they were initially is True
If an equal number of moles of gas is allowed to escape rapidly from each tank, the temperature of the butane tank will be lower than that of the propane tank is True.
Answer:
45.864N
Explanation:
Using the formula
F = nR
n is the coefficient of friction
R is the normal reaction
R = mg
F = nmg
F = 0.78 * 6 * 9.8
F = 45.864N
Hence the amount of force with which the hand pushes the box is 45.864N
