Answer:
A short circuit is when there is a low resistance connection between two conductors that are supplying electrical power to a circuit. This would generate an excess of voltage streaming and cause excessive flow of current in the power source. The electricity will flow through a 'short' route and cause a short circuit.
<span>Answer:
We heated up the liquid CFC from 11.05 degrees celsius to its boiling point (47.6 degrees)
That means we heated it up 36.55 degrees
The formula to solve this is C = Q / M x dT
where
C is the specific heat of the liquid CFC (.91 J/G/C)
Q is the amount of heat required (what we're trying to find out)
M is the mass (52.5 grams)
and dT is the temperature difference (36.55 degrees)
Now put in the values and find out what Q is
.91 = Q / 52.5 x 36.55
.91 = Q / 1918.875
Q = 1746.17 joules to heat up the liquid CFC</span>
Answer:
convection could be a pot on a stove, radiation could be the sun and heat waves, and conduction could be a cup with coffee.
Explanation:
Conduction occurs when two objects are in direct contact with each other.
Convection is the transfer of heat through liquids and gases. Convection occurs above a hot surface because hot air expands and rises and is replaced by cooler, denser air.
Radiate energy is given off by a hot object and directly absorbed by another cooler object. This cause the cooler object to get warmer. Radiation can occur even if no air is present.
Heat can be transferred from one material to another by direct touch (conduction), by differences in density of a fluid (temperature difference), and by RADIATION
