Combustibility is a chemical property that can give off heat, such as in the process of burning wood or fuels.
A pot on a stove gives off radiant heat that heats up the pot and the food inside it. This heat is transferred through direct contact between the pot and the stove burner.
Yes, most chemical reactions that give off light also produce heat. This phenomenon is known as chemiluminescence, where the energy released during the reaction is emitted as both light and heat. However, not all reactions that produce light necessarily produce heat, as some reactions can be endothermic and absorb heat instead.
A reaction that gives off energy is an exothermic reaction. The reaction will give off energy in the form of either heat or light An example of an exothermic reaction would be the curing of concrete. One chemical reaction that will give off heat is the mixture of Caustic Soda and water. The water dissolves the Caustic Soda which in turn generates heat. There are two types of reactions. Exothermic reactions give off heat, and endothermic reactions require that heat be added to make them work. Be careful with exothermic reactions. A rapid, energetic exothermic reaction is called an "explosion".
Theoretically it can last and does not spoil for a VERY long time BUT Methanol can absorb water once opened. Check that the methanol is clear and not milky. I have heard that it goes brownish when off.
On average, humans give off about 100 watts of heat energy.
On average, a person gives off about 100 watts of heat in a day.
yes
On average, a human body gives off about 100 watts of heat.
the 3rd aeriola ;) msharpe!!
All people what or black give off heat.
Yes.
it gives off a great deal of heat
The sun emits 1.2×1034 J each year.
Heat.
No, ice does not give off heat. In fact, ice absorbs heat from its surroundings in order to melt and become liquid water.
A: There are million of small devices involved each dissipating a small heat but the accumulation is in the millions so there is heat to dissipate
