What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
How do particles heat up?
Whenever direct heat is given to any kind of particles/materials, an exothermic reaction occurs. When an exothermic reaction occurs, heat is released. This is what causes the particles to heat up.
Contrast endothermic and exothermic reactions?
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.
Is frezzing endothermic or exothermic?
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.
What is enothermic?
It is a definition for when a chemical reaction occurs and the temperature increases.
Example of exothermic?
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.
When heat is increased does the chemical reaction speed up?
The effect of heat on a chemical reaction will depend on whether the chemical reaction is exothermic (producing heat), or endothermic (requiring an input of heat). If the reaction is endothermic, then adding heat will increase the speed, but the opposite is true for an exothermic reaction.
Is burning of wood a endothermic change?
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.
What is the word used to describe a chemical reaction in which energy is released?
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.
Describe energy in an exothermic reaction?
Light and/or heat energy can both be produced.
Are their other examples in homes and in industries where heat is used to speed up the dissolving of solutes?
making coffee, or making tea.
What device heats up cold water at home?
The boiler will heat up the water that comes out of the tap or is used in the radiators. Also the kettle will heat up cold water to make a cup of coffee or tea
