When a endothermic reaction happens, you may be able to notice a drop in temperature. Sometimes, endothermic reactions need more energy than they can get from their surroundings. In those cases, energy must be added as heat to cause the reaction to take place.
Hope this helps.

What is the sign of ΔT in an endothermic reaction?
ΔH is the enthalpy of the reaction and will be positive in an endothermic reaction and negative in an exothermic reaction.ΔT designates a change in temperature. T2-T1 = ΔTOften the change in temperature will be negative for an endothermic reaction.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
endothermic reaction
How will you judge whether a chemical reaction is exothermic or endothermic in nature?
A chemical reaction is exothermic if it releases heat to its surroundings, causing an increase in temperature. On the other hand, a reaction is endothermic if it absorbs heat from its surroundings, resulting in a decrease in temperature. This can be determined by measuring the temperature change during the reaction or by analyzing the enthalpy change of the reaction.
Is an endothermic reaction one in which heat is transferred from the surroundings to the reactants?
Yes, an endothermic reaction is one in which heat is absorbed from the surroundings and transferred to the reactants. This results in a decrease in the temperature of the surroundings as energy is taken in during the reaction.
What happens to the energy absorbed during and endothermic reaction?
During an endothermic reaction, energy is absorbed from the surroundings, typically in the form of heat. This energy is used to break chemical bonds in the reactants, allowing the reaction to proceed. As a result, the temperature of the surrounding environment may decrease, and the products of the reaction have higher energy than the reactants. Overall, the absorbed energy is stored within the chemical bonds of the products.
What happens during an exothermic reaction and how does it differ from an endothermic reaction?
During an exothermic reaction, heat is released to the surroundings, resulting in an increase in temperature. In contrast, an endothermic reaction absorbs heat from the surroundings, causing a decrease in temperature.
How do you determine if a reaction is endothermic?
An endothermic reaction is determined by observing if heat is absorbed or taken in during the reaction. If the surroundings feel cooler or if the temperature decreases during the reaction, it is likely endothermic.
What is the sign of ΔT in an endothermic reaction?

When the temperature changes cause of a reaction is it exothermic or endothermic?
If the temperature increases during a reaction, it is exothermic. This means that heat is being released into the surroundings. If the temperature decreases during a reaction, it is endothermic, meaning heat is being absorbed from the surroundings.
How would you know if a reaction was endothermic or exothermic?
An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.
How can one determine if a reaction is endothermic or exothermic without relying on enthalpy values?
One way to determine if a reaction is endothermic or exothermic without using enthalpy values is by observing the temperature change during the reaction. If the temperature increases, the reaction is likely exothermic, releasing heat. If the temperature decreases, the reaction is likely endothermic, absorbing heat.

What happens to heat during an endothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings in order to break chemical bonds and allow the reaction to proceed. This absorption of heat causes the surroundings to cool down as energy is taken in by the reacting molecules.
What happens when delta h is positive?
When ΔH (the change in enthalpy) is positive, it means that the reaction is endothermic, absorbing heat from its surroundings. This indicates that energy is being consumed rather than released during the chemical reaction.
What is a chemical reaction in which more energy is taken in than given off?
An endothermic reaction is a chemical reaction in which more energy is taken in than given off. This means that energy is absorbed from the surroundings during the reaction, causing a decrease in temperature. An example of an endothermic reaction is the reaction between baking soda and vinegar.
