it slows down
Cold temperatures reduce blood flow which reduces the function of the hands.
Starfish can not tolerate a wide range of temperatures. When to cold a starfish will shribble up and shrink until death.
No, this would be contrary to the definition of an ordinary chemical reaction.
Single Replacement Reaction.
atoms are not lost or gained in a chemical reaction
Endothermic reaction
It usually lowers their effectiveness, i.e. slows the reaction rate.
Cold temperatures reduce blood flow which reduces the function of the hands.
I think you mean "Cold Fusion" It is the (currently) hypothetical nuclear fusion reaction which happens at ambient temperatures?
Water has the same components at any temperature, hot to cold. The reason cold water is cold is because it has less heat (the atoms of water are moving more slowly than at higher temperatures). the colder the water is, the slower its atoms are moving. So, the difference is heat, not what's in it (its composition).
1:1 The number of atoms does not change in a reaction.
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.
Starfish can not tolerate a wide range of temperatures. When to cold a starfish will shribble up and shrink until death.
cold temperature
No, this would be contrary to the definition of an ordinary chemical reaction.
The nuclear reaction when atoms split is called fission. Fission is where atoms split into smaller particles or atoms.
No. Cold and flu viruses are unaffected by cold or even freezing temperatures.
