Is decomposition of limestone endothermic or exothermic?
endothermic
Is liquid to solid exothermic?
No. Going from solid to liquid at constant temperature is an endothermic process. The required amount of energy is called "heat of fusion" of the material that changes state.
How endothermic and exothermic reactions influenced improved and changed modern life?
All around us are chemical products; and chemicals are obtained by endothermic or exothermic reactions.
Is thermal decomposition a endothermic or exothermic reaction?
Thedecompositionof water is endothermic since energy is required to break up the bonds between the hydrogen and oxygen in the water molecule. Therefore the decomposition of water absorbs energy, making the reaction an endothermic one.
Is the breakdown of glucose endothermic or exothermic?
Exothermic. Glucose is one of the major source of energy of the body and can only act as an energy source because its breakdown into CO2 is an exothermic reaction.
Is liquid to a gas endothermic or exothermic?
It is exothermic. The gas must release energy to its surrounding to become a liquid.
Is a liquid endothermic or exothemic?
A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.
Is burning gasoline an exothermic process or an endothermic process?
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Is evaporating always an exothermic reaction?
No, evaporating is not always an exothermic reaction. Evaporation is the process of a liquid turning into a gas, and whether it is exothermic or endothermic depends on the specific conditions such as temperature and pressure.
Is liquid exothermic or endothermic?
Depends, Liquid can be both endothermic and exothermic, for example water, if you freeze water and put it in room temperature it will be endothermic, meaning it will absorb the heat form the room. And if you Boil water and put it in a cold place it will become exothermic because its releasing the heat.
Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
Is solid exothermic or endothermic?
A solid is itself neither endothermic or exothermic. However the phase change from liquid to solid will likely be exothermic.
Is vaporization exothermic or endothermic?
It is endothermic. Endothermic is to gain heat and Exothermic is to lose heat.
Is the process of condensing exothermic or endothermic?
Condensation is considered a type of exothermic reaction. Condensation is something that is released, which means that is exothermic instead of endothermic.
Is condensation exothermic or endothermic change?
Condensation is an exothermic change because it releases heat energy as water vapor transforms into liquid water.
Which phase changes are endothermic?
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.
What are 3 phase changes of exothermic?
Solid to liquid (melting): This phase change requires energy to break the intermolecular forces holding the solid together, resulting in an endothermic process. Liquid to gas (vaporization): This phase change requires energy to overcome the intermolecular forces between liquid molecules, also an endothermic process. Gas to liquid (condensation): This phase change releases energy as gas molecules lose kinetic energy, forming stronger intermolecular forces in the liquid phase, and is an exothermic process.
