What else can I help you with?
When matter undergoes change of state what does it absorb or release?
Energy.
When matter changes can it absorb heat energy or release heat energy without a corresponding change in temperature?
no.
Does vaporization absorb or release energy?
Vaporization absorb energy.
Do cold packs absorb energy?
No, they release energy.
Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
When there is a chemical change is there an absorption of energy?
Yes, in a chemical change, energy is either absorbed or released. Endothermic reactions absorb energy from their surroundings while exothermic reactions release energy. The change in energy is often required to break and form chemical bonds during the reaction.
What is the relationship between heat capacity and heat energy transfer in a system?
The heat capacity of a system determines how much heat energy it can absorb or release without a significant change in temperature. A system with a higher heat capacity can absorb or release more heat energy without a large temperature change, while a system with a lower heat capacity will experience a larger temperature change for the same amount of heat energy transfer.
Do endergonic reactions absorb more energy than they release?
Yes, endergonic reactions absorb more energy than they release. These reactions require an input of energy in order to proceed, and the energy absorbed is greater than the energy released during the reaction.
WOULD AN ELECTRON HAVE TO ABSORB OR RELEASE NEW ENERGY TO FALL FROM THE THIRD ENERGY LEVEL TO THE SECOND ENERGY LEVEL?
It would release energy. It had to absorb it in order to get from 2 to 3. Law of conservation of energy says it must now release it to fall back.
Do all reactions release energy?
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
How is endothermic reactions differ from exothermic reactions?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.
Is evaporation of water release of energy?
Evaporation is an endothermic process, absorb energy.
