In a hairdryer, an exothermic reaction occurs primarily through the conversion of electrical energy into thermal energy. When the hairdryer is turned on, electricity flows through a heating element, which heats up as resistance causes energy loss in the form of heat. This heat is then blown out by a fan, efficiently drying hair as moisture evaporates. The process is exothermic because it releases heat, warming the surrounding air and the hair.
What else can I help you with?
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
Which reaction occurs when energy is released?
Chemical bonds are broken.
What type of reaction occurs if two substances are chemically combined and there is a release of energy?
Exothermic
Is fireworks an example of exothermic change?
It's a exothermic reaction because heat and light is being released.
What conditions must be met for a reaction to be exothermic?
For a reaction to be exothermic, it must release heat energy to the surroundings. This usually occurs when the energy of the products is lower than the energy of the reactants. Exothermic reactions are often accompanied by an increase in temperature.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
What chemical change occurs so that heat is given off?
this occurs in an exothermic reaction
Is the reaction of magnesium sulphate and water exothermic or endothermic?
The stuff is actually used in some hotpacks. It's exothermic.
Which reaction occurs when energy is released?
Chemical bonds are broken.
What type of reaction occurs if two substances are chemically combined and there is a release of energy?
Exothermic
How do you know that a sealed calorimeter is a closed system?
There is an exothermic reaction that occurs when a closed system exists when using a sealed calorimeter. This exothermic reaction can be identified when energy is being released into the environment.
Is fireworks an example of exothermic change?
It's a exothermic reaction because heat and light is being released.
What conditions must be met for a reaction to be exothermic?
For a reaction to be exothermic, it must release heat energy to the surroundings. This usually occurs when the energy of the products is lower than the energy of the reactants. Exothermic reactions are often accompanied by an increase in temperature.
Is the reaction endothermic or exothermic, and what is the enthalpy of the reaction?
The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.
When an exothermic reaction occurs in a water solution what happens to the temperature of the solution?
The temperature rises. An "exothermic" reaction releases heat energy in the process.
A chemical reaction in which heat is released is?
exothermic reaction .
