Is a puddle of water evaporating endothermic or exothermic?
The evaporation of a puddle of water is an endothermic process because it requires energy input to break the hydrogen bonds between water molecules. Energy is absorbed from the surroundings, causing the temperature of the puddle to decrease as the water evaporates.
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.
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
A chemical reaction that releases energy is called?
Exothermic reactions
What change of state occur when a puddle disappears?
The change of state that occurs when a puddle disappears is evaporation. The liquid water in the puddle turns into water vapor and escapes into the air.
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 a puddle of water evaporating endothermic or exothermic?
The evaporation of a puddle of water is an endothermic process because it requires energy input to break the hydrogen bonds between water molecules. Energy is absorbed from the surroundings, causing the temperature of the puddle to decrease as the water evaporates.
Water evaporating from a puddle is an example of a?
It is a simple evaporation.
Evaporating alcohol endothermic or exothermic?
It is an endothermic process.
Is a puddle evaporating reversible?
Yes, the process of a puddle evaporating is reversible. When water evaporates from a puddle, it turns into water vapor, which can later condense back into liquid form through a process called condensation when the conditions are right, such as cooling temperatures.
A reaction that releases energy as it occurs is classified as?
A reaction that releases energy is exothermic.
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.
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
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.
A chemical reaction in which heat is released is?
exothermic reaction .
A reaction that releases energy in the form of heat?
An exothermic reaction releases energy in the form of heat. This type of reaction typically results in a rise in temperature in the surrounding environment. Examples include combustion and neutralization reactions.
What kind of chemical reaction is an exothermic reaction?
Exothermic reaction: reaction with release of heat; for example burning of organic materials (oxydation of carbon) is a typical exothermic reaction.
