Normal household current is carried over a 10/2 wire. This is good to carry up to 20 amps. The more amps you wish to carry the larger the wire required. The smaller the number the larger the wire. 8/2 is larger than 12/2.
outside of the "standard room temperature" of the resistance of a given size of wire there is something called "heating losses" in any given size of wire ... simply put, the resistance of a given length of wire increases as it's temperature increases... drawing current thru a wire causes a certain degree (no pun intended) of heating, thus raising the resistance and lowering the voltage/current available to the load... normally (with the proper size of wire for the length of run) these effects (rt resistance/heating losses) are minimal. another name for the heating losses is "IRsquared loss" .
Melting ice absorb energy. Energy is used to convert it into water.
melting gains heat energy
The energy gained (absorbed) by the substance is what causes the melting.
yes. It takes energy to raise the temperature of the solid to the melting point.
Melting ice is an example of conduction.
Amperage is the energy carried by each unit of a current
A solid melts by aquiring energy from its surrounding enviorment. So the environment loses energy but the melting solid gains it.
Particles absorb energy when boiling (vapourising), melting and subliming. Particles release energy when freezing and condensing.
Amperage (energy) required to make starter turn fast enough to start vehicle usually not more than 250 amps
Boiling, evaporating, and melting require heat energy.
Energy is required in the melting process because high is needed to melt something
the heat energy got converted and was used for melting.the heat energy was spent to convert solid into liquid state
Melting requires energy input or absorption because liquid water has more energy than solid water.
The melting substance is absorbing energy.
It takes in energy.
Melting occurs when a solid gains thermal energy. Solidification occurs when a liquid loses thermal energy.
Melting requires energy: the heat energy in your drink is used to melt the ice.
A melting point is a periodic property. Melting point is basically the amount of energy required to break chemical bonds. The more energy required, the stronger the bonds and the higher the melting point. For example, Since Ionic bonds have a transfer of electrons, it requires a lot of energy to break the bonds and has a higher melting point.
Freezing is from liquid to solid, so you lose energy. But melting is from solid to liquid so you gain energy.
Thermal energy absorption
No. When a substance melts it absorbs energy.
The substance that melts must absorb energy from its surroundings.
