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.

A 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
That 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.
Something 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.
Thermal energy is transferred from from regions of hot to regions of cold. When thermal energy is transferred from one thing to another, the particles in that matter move more causing heat.
The temature increases or goes up.
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.
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.
Endothermic.
it makes the substence colder
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.
Endothermic 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.
Endothermic reaction.
they contract
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).
Endothermic.
it makes the substence colder
An endothermic reaction is one that absorbs heat from the surroundings.
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.
