Both types (hot and cold) of packs can be easily transported and used in travel. They do not take up a lot of room in a bag or box. If someone were to get hurt, a cold pack can quickly be used to help them. The same goes with a hot pack.
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
Organisms living in very hot areas are called thermophiles, while those living in very cold areas are known as psychrophiles.
One extreme is very, very cold. The other is very, very hot.

One example of an item you can put in a freezer that stays hot is a heat pack, also known as a hot pack or hot water bottle. These packs are designed to retain heat and can be stored in the freezer to be used as a cold compress when needed.

Hot packs are used to soothe and relax muscles by increasing blood flow, while cold packs are used to reduce inflammation and numb pain by constricting blood vessels. Hot packs are typically used for chronic injuries or to help loosen tight muscles, while cold packs are used for acute injuries or to reduce swelling.

Hot, moist packs can be made using a reusable hot pad and a damp towel. Heat the hot pack according to manufacturer's instructions then wrap it in the towel that is damp from hot water. Hot moist packs alternated with cold packs can be used to treat swelling and pain after sprains and strains.
Hot packs are used to provide relief for muscle stiffness, promote blood flow, and relax muscles. Cold packs are used to reduce inflammation, numb pain, and help minimize swelling. They work by different mechanisms and are used at different stages of injury.
You can use a cooler with ice packs or frozen gel packs to keep liquids cold while on a trip on a hot day. Make sure to seal the containers tightly and place them at the bottom of the cooler for better insulation. Avoid opening the cooler frequently to maintain the cold temperature inside.
FIRE for HOT andICE for COLD
very,very hot/cold
Hot packs and cold packs eventually return to room temperature because of the process of thermal equilibrium. This means that the packs exchange heat with their surroundings until they reach a balanced temperature. Heat flows from the hotter pack to the cooler room, or vice versa, until both reach the same temperature.
The words hot & cold are relative.90 c = 194 f.For humans, that temperature is very, very hot.Too hot for us to live.
