Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
What do understand by glass transition temperature. Explain whether it is exothermic or endothermic?
glass transition is a change in state. when the state changes from crystalline or rather glassy to a rubbery like state. it should be noted that it is not melting. it is a state change and not a phase change. it is endothermic phenomena because heat is given to a system so that glass transition occurs. because no heat is released during the process it can not be considered to be endothermic.
What chemicals react to make a hot pack hot?
Yes, hot packs have exothermic reactions (the contents create heat) and cold packs have endothermic reactions (they require heat to occur, therefore making the surroundings colder). In hot packs its a reaction between water and a salt solution, and in cold packs its normally water and ammonium nitrate. peeace
Chemistry model questions of plus one?
What is the atomic number and mass number of an atom with 12 protons and 14 neutrons? Explain the difference between an element and a compound. How many valence electrons are there in an atom of chlorine? What is the difference between an exothermic and endothermic reaction? Define the terms solute and solvent and give an example of a solute-solvent mixture in everyday life.
Can combination reaction be oxidation reaction Explain?
No
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.
Explain which type of reaction exothermic or endothermic would be required to make a cold and a cold pack or hot pack?
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.
Is the process of celular respiration exothemic or endothermic explain your answer?
exothermic
Is breathing an endothermic or exothermic reaction?
Breathing is an exothermic reaction. To explain clearly, during digestion food particles break down into smaller particles. These turn into glucose, this glucose combines with the oxygen present in the cell and provides energy. The special name of this reaction is respiration. It releases heat so it is an exothermic reaction.
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
Explain what it means for a reaction to be endothermic and what would happen to the temperature recorded by a thermometer in an endothermic reaction?
An endothermic reaction absorbs heat from its surroundings to proceed, resulting in a decrease in temperature of the surroundings. This decrease in temperature would be observed on a thermometer, as the heat is being taken in by the reaction rather than being released into the environment.
Explain why the theoretical lattice energies become less exothermic from AgF to AgI?
The decrease in exothermicity in theoretical lattice energies from AgF to AgI is mainly due to the decrease in the charge density of the anions as you move from fluoride to iodide. The larger iodide ions are less able to polarize in response to the cation, resulting in weaker electrostatic interactions and a less exothermic lattice energy.
In an endothermic reaction are the products more or less stable than the reactants and explain your answer?
In an endothermic reaction, the products are generally less stable than the reactants. This is because the reaction absorbs heat from the surroundings to proceed, indicating that the products have higher potential energy than the reactants.

glass transition is a change in state. when the state changes from crystalline or rather glassy to a rubbery like state. it should be noted that it is not melting. it is a state change and not a phase change. it is endothermic phenomena because heat is given to a system so that glass transition occurs. because no heat is released during the process it can not be considered to be endothermic.
