Best Answer

any reaction that takes up heat cools the surrounding and are thus called ENDOTHERMIC reactions.

ex: - thermal decomposition

in these reaction a compound takes up heat from the environment to break down into other substances.

ex: - CaCO3 ==> CaO + CO2

An endothermic reaction takes up heat from the surroundings, causing the surroundings to become cooler. This is because the reaction requires an input of energy in the form of heat to proceed, which is absorbed from the surroundings, resulting in a decrease in temperature.

What is the difference between an exothermic and an endothermic chemical reaction?

In an exothermic reaction, energy is released in the form of heat, making the surroundings warmer. In contrast, an endothermic reaction requires energy input from the surroundings to proceed, making the surroundings cooler as it absorbs heat.


When propane reacts with oxygen does the surroundings area become warmer or cooler?

The surroundings become warmer when propane reacts with oxygen as it undergoes combustion, releasing heat energy as a byproduct of the reaction.


Why does a change in teperature indicate that a change reaction may have occured?

Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.


What is different between exothermic and endothermic reactions?

If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.


What does it mean if the change in enthalpy value for a chemical reaction is positive?

A positive change in enthalpy for a chemical reaction indicates that the reaction is endothermic, meaning it absorbs heat from its surroundings. This typically results in the surroundings feeling cooler.


Why do some areas of the photosphere become cooler than surroundings areas?

A blank reaction is a reaction in which energy is absorbed?

In a blank reaction, energy is absorbed from the surroundings, causing the surroundings to feel cooler. This is an endothermic reaction because energy is required for the reaction to occur. Examples include melting ice or mixing ammonium nitrate with water.


Are sunspots hotter than the surroundings?

No, they are cooler.


Why does ammonium nitrate get cold in water?

When ammonium nitrate dissolves in water, it absorbs energy from the surroundings to break the bonds between its ions. This absorption of energy causes the surroundings to become cooler, leading to a decrease in temperature.


What are dark areas cooler than their surroundings?

sunspot

How does endothermic reactions affect room temperature?

Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature in the room where the reaction takes place. This can make the room feel cooler as the reaction uses up the heat energy present in the environment.
