Does alcohol absorb cold?

No. Its evaporation uses heat energy and causes it to cool.


Do ice packs take in or give off heat energy?

Ice packs absorb heat energy from their surroundings, causing them to cool down. When placed on the body, the ice pack absorbs heat, which lowers the temperature of the area it is in contact with.


How do gel cold packs work?

Gel cold packs work by storing energy in the form of thermal energy, which is released when the pack is activated. The gel inside the pack absorbs heat from the surroundings, causing it to cool down. When applied to a warm or injured area, the cold pack transfers this stored thermal energy to the body, resulting in a cooling effect that helps reduce pain and inflammation.


What absorbs radiant energy?

Darker colours (ex. black, navy blue) absorb more radiant energy than light colours, like white. Also, it helps if the surface is dull (not shiny) and cold at the beginning, because cold things absorb more radiant energy.


What are reactions that absorb energy from the environment?

Endothermic reactions absorb energy from the environment. These reactions typically have a positive enthalpy change and require an input of heat or energy to proceed. Examples include the reaction between citric acid and baking soda in a cold pack.


Are heat and cold packs reusable for multiple uses?

Yes, heat and cold packs are typically reusable for multiple uses.

Can you get 2 energy packs in Mafia Wars in one day?

No. Energy packs are available every 24 hours


How do you get your lotto win in Mafia Wars?

The "energy packs" you "win" are not real energy packs. They are not missing ... the developers have said that the energy packs are simply replacements because "most players are not fortunate enough to receive energy packs from their mafia." So if no one sends you an energy pack for the day, you can use your lottery won energy pack, but only once every 23 hours.


How do cold packs work?

Instant hot and cold packs are used by athletes to quickly and conveniently treat an injury. They last for about 20 minutes. The packs take advantage of chemicals that either absorb a lot of heat or release a lot of heat when dissolved in water. When a chemical process absorbs a lot of heat it is called endothermic. When heat is released, it is called exothermic. In cold packs, ammonium nitrate is used because it absorbs a lot of heat when it dissolves in water. The water and ammonium nitrate are in separate compartments in the pack. When the cold pack is needed, the chambers are broken and the ammonium nitrate dissolves in the water, absorbing heat and making the pack as cold as 0C. In hot packs, calcium chloride or magnesium sulphate are used, along with the water. They release heat when the chambers are broken and the chemical dissolves in the water. A hot pack can reach a temperature of 90C. :)
