A lab group was given a candle, a match, a strip of cloth, tongs, and a metal can. They were asked to use these materials to mod

Troyanec [42]

Answer:

The materials with which the lab group are to use for the model includes;

i) A candle

ii) A match

iii) A strip of cloth

iv) Tongs

v) A metal can

The processes the lab group are to model are;

a) Conduction

b) Convection

c) Radiation

The procedure the lab group can use to do this is outlined as follows;

1) Tie the piece of cloth around the metal can with a strip of the cloth extending past the bottom of the can

2) Hold the metal can in with the aid of the tongs

3) Light the candle with the match

4) Place the metal can over over the burning candle so that it does not touch the flame

5) While holding the can with the tongs, ensure that the strip of cloth hanging by the side of the can does not come in contact with the flame

Conduction

Conduction heat transfer is observed by the rising temperature of the tongs that is in the contact with the can

Convection

Convection heat transfer is observed by the rising temperature of the can that is placed in the path of the rising convection current from the candle wax

Radiation

Radiation heat transfer is observed by the shrinking of the piece of cloth placed beside the candle flame

Does heat rise or fall?? the last person that answered did it just for the points and gave me no real answer

nasty-shy [4]

Heat does not rise or fall because it is an energy being transferred. It is the hot air which rises because colder air is denser than hotter air.

How will a current change if the voltage in a circuit is held constant while the resistance doubles? 1. it's impossible to predi

laila [671]

According to Ohm's Law:

$I = \frac{V}{R}$

Where: V = Voltage
I = Current
R = Resistance

As you can see here, you can say that Current is directly proportional to Voltage and indirectly proportional to Resistance. This means that as the voltage increases, current increases and as the resistance increases, current decreases.

So in your scenario, if the voltage remains the same, but the resistance is doubled, that means that the current will be halved. So the answer to your question is 2. the current will drop to half of its original value.
