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:

Explanation:

1.The particles move faster, and their average kinetic energy increases.

If the temperature of gases are increase, the gas particles will gain more kinetic energy and they will begin to move randomly and haphazardly in the container that contains them. Temperature is directly proportional to increase in kinetic energy of gases.

2. The entire container because gases will expand to fill it.

Gases fills up containers and they assume the volume and shape of wherever they are put into. Therefore, the volume of occupied by a gas is actually the volume of the container they occupy. Gases are able to do this because they are free.

3. Because the attractive forces between gas particles are negligible, gas particles can glide easily past one another.

Gases acts fluid because they have little to no intermolecular attraction between them. Therefore they have low density and close to zero packing. This makes them easily glide past one another and this is why they act fluid.

4. Solid

Solids are arranged in a particular pattern. The molecules are close together and they vibrate about a fixed position. Ordered arrangements of particles of solid gives them their unique shapes.

5. Gas particles spread out to fill a container, leading to a low density of the gas.

Density is defined as the amount of substance i.e mass per unit volume. If you have more mass occupying a particular volume, then density will be high. For gases, they move to fill the containers that houses them and so they have low density.

6. Solids have low compressibility compared to liquids.

Gases are the most compressible form of matter. Solids are not easily compressible because their particles have a well ordered arrangement. Solids are rigid and do not readily move. Therefore, they readily restrain compressive forces on them. Liquids molecules moves about within the liquid. They are slightly compressible.
