You have placed a copper pot with water to heat on the stove. After one minute you place your finger in the water and you are okay. When you touch the pot your finger gets burned. Upload a drawing of a molecular view of what the copper atoms and water molecules look like at the beginning of heating the pot and after the pot has been heated for 15 mins.

Expert Solution

Clearly, at t = 0, there is not enough heat to change temperature

water molecules are not that high on T, therefore, they move slowly.

The pot will start heating first, due to the contact with the heat source.

Note that copper is a good conductor of heat

it will icnrease its Temperature readily

From the diagram, initially, the molecules of wter move slowly,

the atoms of copper are near each other since they are compact, i.e. denser (not to sacale)

in the 15 mins later diagram

water has started to vaporize due to the kinetic energy / temperature of the molecules

Also, copper molecuels are far away since they started to expand

Inventor jockey will in a way heat a pot of water by freezing one other amount of water. a) He wants to heat 1.5 kg of water from 0.0 to 80.0 ºC in a closed and well insulated container. How much water at 0.0 ºC does he then have to freeze? b) Does the invention contradict the first theorem of thermodynamics? Motivate your answer.

A pot of water is boiling under one atmosphere of pressure. Assume that heat enters the pot only through its bottom, which is copper and rests on a heating element. In two minutes, the mass of water boiled away is m = 3.5 kg. The radius of the pot bottom is R = 10.0 cm and the thickness is L = 1.0 mm. What is the temperature of the heating element in contact with the pot?

You are warming up 2 kg of soup in a pot on a stove. The soup (C=4 kj/kg/K) starts at 4ºC. You have it on a heating element that is drawing 1.2 kW of power. 15% of the heat from the element is going directly to the air. Of the heat going into the pot, 20% is lost by heat transfer to the room. You are stirring vigorously and add 25 KJ of energy to the pot. How long will...
