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.
Why do all transformations of energy have a little bit of heat energy?
In all transformations, either energy is absorbed or released. So the reactions involved are either endothermic or exothermic.
How is the energy trapped in ATP?
Energy is trapped in ATP through the biological processes of the Krebs Cycle and the catabolic processes involved in photosynthesis. The ATP or adenosine triphosphate captures the energy that is created by the cellular reactions.
Where does the energy come from that is needed for an endothermic reaction the products or the reactants?
-The Productt/reactant solution -The envoriment when no solution is involved
High energy is a requirement for fusion reactions to occur because nuclei involved?
Repel each other because they have like charges
Is paper burning with a bright flame a exothermic reaction or endothermic reaction?
Reactions with oxygen (air) involved, like burning paper, are exothermic. Exception: formation of many nitrogen-oxygen compounds (NOx) are endothermic.
Examples of endothermic and exothermic reactions?
Exothermic reactions give out energy overall. Here are some exothermic reactions:- Combustion of fuels such as hydrogen & methane- Neutralisation of an acid by an alkali- Reaction between sulphur & ironEndothermic reactions take in energy overall. Here are some endothermic reactions:- Reactions involved in cooking- The thermal decomposition of calcium carbonate- Photosynthesis in which plants use sunlight, carbon dioxide & water to make their own food

How is energy involved in a chemical reaction?
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
Is paper burning with a bright flame a reaction of exothermic or endothermic?
When a piece of paper burns, the energy stored within the fibers of the paper is released as heat energy. This exergonic reaction produces more energy than it takes to perform.
What is the description of chemical reactions involved in cooking when cooking requires continuous addition of energy to the chemical reactions?
endothermic reaction
What is a reaction in which heat is involved?
A reaction in which heat is produced is called exothermic. A reaction in which heat is absorbed (or one that produces cold) is called endothermic.
What are the ways that heat takes part in a chemical changes?
Heat can be involved in a chemical reaction that is endothermic(absorbs heat) or that is exothermic(releases heat)
All chemical breakdown processes in cells directly involved?
reactions that are controlled by catalysts
Is the dissolution of calcium hydroxide exothermic or endothermic?
Exothermic: Heat is given off as one of the products. The container holding the reactants and the products gets hot during the reaction. Use approximately 5 mL of 6M HCl and add to a testtube containing a small peice of mossy Zn. Immediately place a thermometer in the testtube and you will see a quick rise in temperature. This rise in temperature indicates that heat is given off which is a clear sign of an exothermic reaction. Hope this helps!!
Was it exothermic or endothermic?
In chemical reactions, the reaction involves a change in the amount of energy in the chemicals involved. In some reactions the chemicals have less energy when the reaction is complete, since energy has to go somewhere it is given off as heat; this means the chemicals get hotter, because the reaction gives out heat it is called exothermic. Exo as in exit for going out, and thermic for heat, like in the word thermometer. A reaction where the chemicals need more energy after the reaction absorbs energy from its surroundings in the form of heat. This means the heat energy is converted into another form of energy, so with this loss of heat the chemicals cool down. This is called an endothermic reaction. Exothermic gives out heat (warms up) Endothermic absorbs heat (cools down)
