if you were going to choose on of these chemicals for a hand warmer, which would u choose? justify your answer with evidence

If your fingers are cold or your muscles ache, you can use chemical hand warmers to heat them up. There are two types of chemical hand warmer products, both using exothermic (heat-producing) chemical reactions. Here is how they work.

Key Takeaways: Chemical Hand Warmers

Chemical hand warmers rely on exothermic chemical reactions to release heat.

There are two main types of chemical hand warmers. One type releases heat by air activation. The other type releases heat when a supersaturated solution crystallizes.

Air-activated hand warmers are single use products. Chemical solution hand warmers are re-usable.Explanation:

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
