it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.
There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).

What is the name given to reactions which take in heat?
An endothermal (or endothermic) process is the name of the process in which heat is taken in. In an exothermal (or exothermic) process, heat is released.
What name is given to all chemical reactions which releases heat energy?
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.
What is the name of the type of reaction that produces heat?
exothermic reactions1) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An example of this kind of reaction is the burning of napthalene:C10H8 + 12 O2---> 10 CO2 + 4 H2O
What is the scientific name for reactions that give out energy?
The scientific name for the reaction that gives out energy is exothermic
A chemical reaction that produces heat is called?
the name your looking for is an "exothermic" reaction, one in which heat energy is released to the surrounding atmosphere the other is an endothermic, which absorbs the energy around it making it a "cold" reaction

Endothermic and cold blooded is exothermic

What name is given to reaction which give out heat?
Such reactions are called Exothermic reactions.

What is the name given to a reaction the gives off energy?
A reaction that gives off energy is an exothermic reaction. The reaction will give off energy in the form of either heat or light An example of an exothermic reaction would be the curing of concrete. One chemical reaction that will give off heat is the mixture of Caustic Soda and water. The water dissolves the Caustic Soda which in turn generates heat. There are two types of reactions. Exothermic reactions give off heat, and endothermic reactions require that heat be added to make them work. Be careful with exothermic reactions. A rapid, energetic exothermic reaction is called an "explosion".
Are all thermal decomposition reactions endothermic in nature?
Yes, but rather: 'most of all' combination reactions are exothermic. This is mostly true for spontaneous, common reactions.Examples of the contrary endothermic reactions, though rare, are:The formation reaction (= combination 'pur sang') of ethene, propene, acetylene, and even benzene is endothermic, when combined out of elements (that's why they are called endothermic compounds). Further a lot of metal hydride's, chlorous oxide: ClO2 are endothermic.The most Exceptional Endothermic Compound is:Dicyanoacetylene, IUPAC-name: but-2-ynedinitrile, C4N2 (or more structural: NC-CC-CN)Standard heat of formation Ho298 ( 4C + N2 --> ) is 500.4 kJ/molBecause of its high endothermic heat of formation, it can explode to carbon powder and nitrogen gas (reversed formation reaction, exo. 500.4 kJ/mol).It burns in oxygen with a bright blue-white flame at a temperature of 5260 K, which is probably the hottest flame of any chemical.
What is the another name for warm blooded?
The other name for warm-blooded is endothermic, which refers to animals that can regulate their internal body temperature independently of the external environment. This ability allows them to maintain a relatively stable body temperature in various environmental conditions.
Is a whale endothermic?
A whale is endothermic, able to regulate its own body heat. It is a mammal, and all mammals and birds are endothermic. The term 'endothermic' is the correct name for an animal that is warm-blooded.
Can you name another compound whose dissolution will be endothermic?
Dissolution for most substances is endothermic.
