exothermic reactions
what is a example of a exothermic reaction
any combustion reaction. a neutralization reaction. rusting of iron (rust steel wool with vinegar) the thermite reaction. reaction between water and calcium chloride.
what is a endothermic reaction
An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.
what is another word for heat
thermal
can energy be destroyed
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. ... In other words, energy cannot be created or destroyed.
can bees sting other bees
yes
what is the definition of exothermic reaction
An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
is melting ice cubes exothermic or endothermic
endothermic
what is thermal energy
Thermal energy refers to several distinct thermodynamic quantities, such as the internal energy of a system; heat or sensible heat, which are defined as types of energy transfer; or for the characteristic energy of a degree of freedom in a thermal system, where is temperature and is the Boltzmann constant.

what happens in a exothermic reaction
An exothermic reaction occurs when the energy used to break the bonds in the reactants (the starting stuff) is less than the energy released when new bonds are made in the products (the stuff you end up with). ... The reactants have more energy than the end products
What happens in an endothermic reaction?
Endothermic reactions. An endothermic reaction occurs when the energy used to break the bonds in the reactants is greater than the energy given out when bonds are formed in the products. This means that overall the reaction takes in energy, therefore there is a temperature decrease in the surroundings
can heat change matter
yes
what is non moving energy or stored energy

How do you know if a reaction is exothermic or endothermic?
In a chemical equation, the location of the word "heat" can be used to quickly determine whether the reaction is endothermic or exothermic. If heat is released as a product of the reaction, the reaction is exothermic. If heat is listed on the side of the reactants, the reaction is endothermic.
Is cooking an egg endothermic or exothermic?
Endothermic, heat absorbed or in something, exothermic, heat being released or sent out. Endothermic must be supplied with heat and is basically the opposite of exothermic. An everyday reaction is in the cooking of an egg. There must be heat added or absorbed from the environment to cook the egg or any other food item.
where are the basketball team the heat located

who invented energy
Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity, and in 1800 he constructed the voltaic pile (an early electric battery) that produced a steady electric current, and so he was the first person to create a steady flow of electrical charge.

Is food digestion endothermic or exothermic?
Digestion is an exothermic reaction. During the process of digestion complex substances such as starch carbohydrates and proteins are broken down into simpler form such as simple sugar and amino acids respectively. ... Since energy is produced in the process of digestion ,it is an exothermic reaction.
Why is freezing exothermic?
Freezing, the phase transition from liquid to solid form, is an exothermic process because energy, in the form of heat, is emitted in the process. Because freezing/melting is a first-order phase transition, there is a latent heat involved in the transition.
heat happens when the
energy burns or used
where does the word energy come from
The word energy comes from the Greek word energeia.
