1. A cooling system comprising:
a first reactant; a second reactant, wherein the first reactant can endothermically react with the second reactant to absorb heat; and a temperature-responsive divider positioned between at least some of the first reactant and at least some of the second reactant,
wherein at a first temperature, the temperature-responsive divider is impermeable to the first reactant, the second reactant, or the first reactant and the second reactant, andwherein at a second temperature, the temperature-responsive divider is permeable to the first reactant, the second reactant, or the first reactant and the second reactant. |
