Which process is exothermic?
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”
Final answer: Dilution of an acid and Reaction of water with Quicklime are exothermic processes.
Which one of the following processes is exothermic? Condensation of a gas into a liquid. An exothermic process releases heat. Boiling a liquid, melting a solid and converting a solid into a gas all require energy be put into the system.
Answer and Explanation: The combustion of the methane is the most exothermic reaction because a huge amount of heat is evolved from the reaction.
Chemical reactions that absorb (or use) energy are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.
A chemical reaction or physical change is exothermic if heat is released by the system into the surroundings. Because the surroundings is gaining heat from the system, the temperature of the surroundings increases. The sign of q for an exothermic process is negative because the system is losing heat.
Give examples of exothermic reactions.
Combustion reaction, Neutralization reaction, and Respiration.
- Making of an Ice Cube. Making an ice cube is a process of liquid changing its state to solid. ...
- Snow Formation in Clouds. ...
- Burning of a Candle. ...
- Rusting of Iron. ...
- Burning of Sugar. ...
- Formation of Ion Pairs. ...
- Reaction of Strong Acid and Water. ...
- Water and Calcium Chloride.
Therefore, respiration and burning of a candle are examples of exothermic reaction whereas evaporation of water and melting of ice are examples of endothermic reaction.
Because we must add heat, boiling water is a process that chemists call endothermic. Clearly, if some processes require heat, others must give off heat when they take place. These are known as exothermic.
Is melting an exothermic process?
Final Answer: Melting is an endothermic process because when heat absorbs then the physical state will change from solid to liquid.
When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.
The process of boiling water is endothermic. This is mostly because heat must be applied in order for water to boil.
The chemical reaction in which the heat is released is known as an Exothermic reaction. Examples are the burning of a candle and the reaction of a strong acid with water.
Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.
An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
Adsorption is always exothermic.
Evaporation is endothermic. For condensation the molecules are giving up their heat energy. When molecules give up heat energy, it is called exothermic.
A chemical reaction or physical change is endothermic if heat is absorbed by the system from the surroundings. A reaction or change is exothermic if heat is released by the system into the surroundings.
Final Answer: Melting is an endothermic process because when heat absorbs then the physical state will change from solid to liquid.
Is freezing exothermic?
When water becomes a solid, it releases heat, warming up its surroundings. This makes freezing an exothermic reaction.
