DEMONSTRATING

DEW AND FROST

Level 1

EXPERIMENT 16

Equipment:

In one tin can put a mixture of ice and salt, in the other can put only ice.

Note the frost forming on the outside of the can with the ice and salt mixture. Compare this with the liquid moisture on the outside of the can which contains ice only.

Compare the temperatures of the contents of the two cans, noting that the cooler temperature causes moisture to condense in a solid form.
