Heat flow by conduction requires that the two systems must not be touching each another.
<h3>What is heat energy?</h3>
Heat energy is a form of energy that exists due to a temperature difference between two objects.
Heat energy flows from an object at higher temperature to an object at a lower temperature.
Heat transfer by conduction involves the vibration of particles of the medium transferring heat due to contact between the two objects.
Therefore, heat flow by conduction requires that the two systems must not be touching each another.

Since the water is at 100 degrees then it take 40.6 kj/mol to change 1 mole of water at 100 degrees into steam at 100 degrees
the moles of water 8.22mol
since one mole take 40.6kj/mol 8.22mol will be =
8.22mol x 40.6 kj/mol =333.732 kj

Explanation:
Urea Formaldehyde Foam Insulation is the thermal insulation material that is no longer used because of formaldehyde gas emission
Urea Formaldehyde Foam Insulation is mixture of urea formaldehyde resin, foaming acid agent, and a propellant used in the 1970s for insulating purposes.
It was specifically designed to insulate the areas of the building that were hard to access. Unlike regular process, it was sprayed into the walls by using holes.
It is no longer used because it caused a raise in the formaldehyde gas in the residence. This gas caused irritations to the people living in the building. Residents started to report health issues like respiratory problems, and eyes, nose, throat irritation.
