What is it called when two substances get colder in a chemical reaction?

No. temperatures a a measure of motions of particles. As particles slow down the substance gets cold. As a substance gets warmer the particles speed up. Cold is not a thing that you can place on a substance.

∙ 15y agoA solution get warmer as you add a new substance to it because that causes a reaction which causes energy, that energy is transfered to heat energy so there fore it gets warmer.(i may not be completely right but im pretty sure that is why) B.M.H age 13

∙ 14y agoThat is an ENDOTHERMIC reaction. It absorbs heat, rather than giving off heat. The instant cold packs in first aid kits use this property- they contain ammonium nitrate and water- which get cold when combined.

∙ 9y agoSomething can get colder when you add a warmer substance to it if it produces an endothermic reaction. Endothermic reactions are ones where heat is absorbed.

What is thermal reactions?
An Exothermal reaction is a chemical reaction that produces heat making the solution warm or hot. It is the opposite of an Endothemic reaction which makes the solution colder.
What indicates that an exothemic chemical reaction occurs when two substances are mixed together?
Exothermic reactions release heat energy, so they would produce heat (increase in temperature). This can easily be tested by touching the container with your hands, or by using a thermometer. The opposite is an 'endothermic' reaction, which absorbs energy and feels colder.
What is the name of a reaction that occurs when products become colder?
Endothermic.
What occurs to the substances as energy is added to the liquid at 80 C?
it makes the substence colder
When the reactants get colder in an endothermic reaction what has happened to the heat energy?
Endothermic reaction means reactions which absorbs heat energy to carry out reaction. So if the reactants are at colder condition, process/operation require much more heat energy,ie, heat energy consumption will be more.
When two substances get colder in a chemical reation?
Endothermic reaction?
What is ex thermal reaction?
An Exothermal reaction is a chemical reaction that produces heat making the solution warm or hot. It is the opposite of an Endothemic reaction which makes the solution colder.

Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
What is the type of reaction when things get colder?
Endothermic reaction.
What happens to the volume of most substances when they get colder?
they contract
What is the name of a reaction that occurs when products become colder?
Endothermic.
What is one similarity between exothermic reaction and an endothermic reaction?
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
What occurs to the substances as energy is added to the liquid at 80 C?
it makes the substence colder
What is an endothermic reaction?
An endothermic reaction is one that absorbs heat from the surroundings.
An experiment is conducted at 20.0 degrees Celsius and 30.0 degrees Celsius so what would most likely happen to the rate of reaction as the temperature is increased?
Not enough data is supplied to answer this question. Some substances are more reactive to colder temperatures; however, in most cases, the higher temperature would increase the rate of reaction.
