Which property of water allows dogs to cool themselves by panting? -water's high surface tension-the formation of covalent bonds between water molecules- water's high heat of vaporization

water's high heat of vaporization

Explanation:

Water is a substance with a high heat of vaporization (2257 J/g). This means that 1 g of water evaporates, a large amount of heat is absorbed.

The mechanism of evaporation is used by the dog to cool their temperature, by panting. In fact, sweat accumulates on their tongue, then the molecules of water with higher kinetic energies evaporates, turning from liquid into gas, While doing so, they absorb a large amount of heat from the dog's body (thanks to the high heat of vaporization of water), allowing the animal to lower its temperature much efficiently.
