What is a reaction that gives out a lot of heat?
exothermic reaction
How does heat and cold can affect a chemical reaction?
Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
Does a combustion reaction give off or absorb heat?
It's an exothermic reaction, which means it gives off heat.
Is endothermic cold or hot?
cold, because the reaction is releasing heat, therefor making it colder.
What is a chemical reaction that's absorbs energy called?
An Endothermic reaction. If you touch the reaction vessel it will feel cool/cold, as it is taking in heat energy. By contract an Exothermic reaction is one that gives out heat. If you touch the reaction vessel it will feel warm/hot as it is liberating heat energy.
What happens to the reaction during endothermic and exothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
What does endothemic mean?
Endothermic means more energy goes into a reaction than the reaction gives off. It tends to absorb heat (feel cool).
What is a reaction that gives out a lot of heat?
exothermic reaction
How does heat and cold can affect a chemical reaction?
Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.
What term is used for the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
Why does an endothermic reaction feel cold if energy is being absorbed?
Because the energy(heat) is being pulled out of your hand. Heat transfer from the hottest substance to the coldest
What is a endopthermic reaction?
An endothermic reaction is a reaction where heat flows from the surroundings in to the system. Holding an cold pack to your skin is an endothermic reaction; heat flows from your skin (surroundings) into to the cold pack (system).
What term is used 4 the type of chemical reaction that gives out heat energy?
Exothermic reaction gives free heat (energy).
What is a reaction called that gives off heat?
exothermic reactions-gives off heat
What is a reaction in which heat is involved?
A reaction in which heat is produced is called exothermic. A reaction in which heat is absorbed (or one that produces cold) is called endothermic.
What is a chemical reaction gives off heat called?
exothermic reactions-gives off heat
