Is there a chemical that heats up when exposed to cold temperatures?

That depends. If the chemical is already colder than the cold environment then yes it would heat up. There are some compounds such as the iron based power found in hand warmers the seem like the warm up when exposed to the cold, however it is not the cold making them warm. It is the oxidation process happening because of the exposure to oxygen, completely separate from the environmental temperature.
Heat always travels to where it is colder, it is always striving for balance. That is why hot coffee and ice water will both eventually become room temperature.

Why does land near an ocean have less temperature variation from day to night than places inland?
temperatures near water change during the seasons
How does geothermal energy flow from hot to cold or cold to hot?
When the weather is cold, the water or refrigerant heats up as it travels through the part of the loop that's buried underground.
Lower temperatures can be expected behind?
An advancing cold front.
How does the sun provide energy for surface ocean currents?
The sun heats the water, causing cold / hot circulation, and evaporation. It also heats the air, causing wind, which also moves currents.
What are the weather conditions in the polar regions?
Extremely cold temperatures as result of little solar radiation.
How water changes from gas to liquid?
When the liquid is exposed to extreme heats, it evaporates, forming a gas. This is because of the particles shrinking and being able to move around more freely. If it is exposed to cold temperatures, the particles enlarge, so that there is not much room for movement, causing a solid object.
Do crystals grow faster in hot or cold temperatures?
cold it helps there chemical coumpoubds freeze
Will porcelain tile become brittle when exposed to cold temperatures?
yes any tile in the extreme cold becomes severely brittle.
When cold temperatures are produced in a chemical reaction the reaction is known as?
Endothermic reaction
What would cause a five speed manual transmission to shift hard in cold temperatures?
Oil is cold and thick due to ambient temperature as transmission heats up oil thins out
Is it hot or cold and there any difference between the temperature of day and night?
Yes it is hot and cold in the desert. During the day, the desert heats up, which gives them their extreme temperatures. but at night, the desert is very cold.
Will metal crack when it gets too cold?
In extreme cold temperatures, some metals may become more brittle, and may break when exposed to ordinary stresses.
What effect does the cold have on muscle coordination?
cold numbens muscle and decreases swelling. They say to use cold on new injuries and heat on old injuries. also coldness decreases the speed of chemical reactions, but i am unsure weather to use cold for bee stings and such...
Why shouldn't you touch the horn on a co2 extinguisher?
Frostbite! The horn is exposed to temperatures around 100 below zero F. VERY cold!
How do people get freezer burns?
People do not get freezer burns. A person can however get frost bite if exposed to extremely cold temperatures for a prolonged period.
How to Maintain Panasonic Batteries?
To maintain your Panasonic batteries properly, keep them away from extremely cold temperatures. Cold weather is bad for all batteries, and it can immediately begin the process of draining power from the batteries as soon as the electronics are exposed to the frigid temperatures. This is why you may notice devices not working as well in temperatures that are freezing.
Are trombones safe when exposed to cold temp erature?
It's fine for any brass instrument to be exposed to frigid temperatures. However, if the instrument is played while cold, the tone will be extremely flat. To accommodate for the flatness in tone, move your tuning slide in until the instrument is warmed up.
