Pros & Cons The white shows less blemishes, the darker the finish the better the heat wil be kept but the greater the potential algae growth
There is no specific element in plaster that produces. The chemical reaction that results when plaster is mixed with water is what produces the heat.
When you pour plaster into a sandcasting, the chemical reaction between the water in the plaster and the sand causes an exothermic reaction, which generates heat. This heat is trapped within the enclosed space of the mold, making the plaster feel warm to the touch as it sets and hardens.
If there is water in it you can heat it.
The settling of plaster is an exothermic process, meaning it releases heat as it hardens. This heat is generated from the chemical reaction that occurs when the plaster mixes with water and begins to set.
White is better at reflecting heat in a car compared to black. This means that a white car will absorb less heat from the sun, keeping the interior cooler than a black car.
It produces an exthermal heat
Because white reflects the heat from the body, whereas black absorbs the heat in
Plaster of Paris is a classic exothermic reaction. The gypsum when heated to 150 degrees dehydrates with 75% of water content escaping as vapor. When water is reintroduced it resets the crystal lattice and gives off heat.
No, white surfaces are not good radiators of heat. White surfaces are better at reflecting sunlight and heat, which is why they are often used in hot climates to keep buildings cool. Dark surfaces, on the other hand, absorb and radiate heat more effectively.
Tricky question. If the surfaces are the same, then silver will absorb more, but in the case of a silver mirror, it will reflect more light, so the white will absorb more. Save
