Hand warmers typically reach temperatures between 100°F to 130°F (38°C to 54°C). The exact temperature can vary depending on the type of hand warmer, such as disposable, reusable, or electric. Most are designed to provide warmth without causing burns, but it's advisable to avoid prolonged direct contact with the skin. Always follow the manufacturer's instructions for safe use.

Hot chocolate will stay warmer in a Styrofoam cup.
A hand warmer typically uses an exothermic reaction, such as the oxidation of iron, to generate heat. This heat is then transferred to the surrounding materials, such as the pouch or gel, which in turn warms up your hands when you hold the hand warmer.
Thermal energy would flow from the hot drink to your hand, as heat always moves from a warmer object to a cooler one. Thus, the cup's heat would transfer to your hand, making it feel warm.
Use hot water to bring urine to 98 degrees. Then simply use the handwarmer to keep it at that temp

A reusable hand warmer works by using a chemical reaction to generate heat. When the hand warmer is activated, the chemicals inside react with each other, producing heat that can last for several hours. The hand warmer can be reused by boiling it in water to reset the chemicals and make it ready for use again.
