Answer:

Explanation:
Given:
- thickness of the base of the kettle,

- radius of the base of the kettle,

- temperature of the top surface of the kettle base,

- rate of heat transfer through the kettle to boil water,

- We have the latent heat vaporization of water,

- and thermal conductivity of aluminium,

<u>So, the heat rate:</u>


<u>From the Fourier's law of conduction we have:</u>


where:
area of the surface through which conduction occurs
temperature of the bottom surface

is the temperature of the bottom of the base surface of the kettle.
Temperature is a measure of the average kinetic energy of the particles of a substance.
Hope this helps! :)
<span>The factors that are used to determine power are:
Voltage,current and the power factor.

Watts = Volts x Amps x Power Factor</span>
If the same atoms appear on both sides, then it's balanced.
In this reaction, there are 4 Oxygens, 2 Carbons, and 2 Nitrogens on each side. So numerically, <em>it's balanced</em>. But I don't know enough chemistry to say whether the reaction is possible.
The object that goes through chemical change, changes completely to where you can not change it back to its original form. Physical change you can undo
