The chemicals calcium and lithium mixed with carbon make a good exothermic reaction to heat a self-heating can
Heat is released during an exothermic reaction.
In Chemistry, if a reaction produces heat it is an "exothermic" reaction. "Endothermic" reactions are the opposite, in that they suck up or absorb all heat, creating cold.
The energy in a coffee maker is typically electrical energy, which is used to heat up the water and power the machine to brew the coffee.
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
An endothermic reaction absorbs heat. It cannot proceed without the addition of heat. An exothermic reaction releases heat. Since heat causes chemical reactions to go faster, an exothermic reaction can "feed on itself" and get out of control, releasing damaging amounts of heat and, if proceeding in a closed container, causing an explosion.
Yes, you can heat up cold brew coffee by simply microwaving it or pouring it into a pot and heating it on the stove.
Any chemical reaction that releases energy is called an exothermic action. The equations for an exothermic reaction between substance A and substance B would be: A + B --> AB + Heat The heat represents the energy and we can tell it is being released because it is on the product side of the equation. The reverse reaction would be endothermic, meaning it requires energy, heat would be on the reactant side and the equation would be: AB + Heat --> A + B To sum things up, an exothermic reaction releases energy and heat will be on the product side of the equation. An endothermic reaction requires energy and heat will be on the reactant side of the equation.
it is exothermic since it produces energy. if endothermic it would use up energy.
nope. Endothermic reactions involve the reactants including heat, but ending up with colder products. But you started with wood without heat, and ended up with a hot fire. This is an exothermic reaction.
When concrete cures it warms up. Those hand warmers that heat up when they are opened up are exothermic. Desiccants when exposed to a lot off water.
In an exothermic reaction, energy is released to the surroundings in the form of heat. This results in a decrease in the overall energy of the system, as the reactants have more energy than the products. Exothermic reactions typically feel warm to the touch and can sometimes involve the emission of light.
making coffee, or making tea.
