For the electrons in a material to create an electric current THERE MUST BE FLOW OF THE ELECTRONS, CHARGES MUST FLOW CONTINUOUSLY FROM ONE POINT TO ANOTHER.Electric current refers to the continuous flow of electric charges through a material. For an electrons to flow in a material, the material must be a conductor.

What is absolute zero? What is the temperature of absolute zero on the Kelvin and Celsius scales?
salantis [7]

Answer:

Absolute zero = 0 K or - 273°C

Explanation:

Absolute zero :

 When the entropy and enthalpy of the ideal system reach at the minimum value then the temperature at that condition is known as absolute zero condition.

Absolute temperature is the minimum temperature in the temperature scale.The value of absolute zero is 0 K.

We know that

\dfrac{C-0}{100}=\dfrac{K-273}{100}=\dfrac{F-32}{180}

F=Temperature in Fahrenheit scale

K=Temperature in Kelvin scale

C=Temperature in degree Celsius scale

When  K = 0

\dfrac{C-0}{100}=\dfrac{K-273}{100}

\dfrac{C-0}{100}=\dfrac{0-273}{100}

C= - 273°C

Absolute zero = 0 K or - 273°C

The heat flow into the sample in the segment ________ will yield the value of the heat of fusion of this substance
SpyIntel [72]

The heat flows into the sample in the segment <u>    BC    </u>    will yield the value of the heat of fusion of this substance.

<h3>Heat of fusion:</h3>

The heat of the fusion of water is unusually high. The amount of heat required to convert 1 g of solid into a liquid while maintaining the same temperature is known as the heat of fusion. It is a latent heat as well and is occasionally referred to as the latent heat of fusion. Since water only freezes at a single temperature (0 °C), it only has one value, which is 79.71 cal/g, or the rounded amount of 80 cal/g.

In order to control frost, water fuses at a high temperature. The water used for irrigation is frequently consistently above freezing when it is extracted from the ground.
