参考答案:
The mechanism of evaporation of the water from
the moist cloth jacket requires energy (the latent heat of vaporization), some
of which will come from the interior of the canteen. This removal of energy from the interior
helps to keep the interior of the canteen cool.
Also, the metal canteen is a good thermal conductor, and so heat can
transfer from the water to the cloth jacket to cool the water.
