In which source of water would a wave travel the fastest? ice cold room temperature hot

hot

Explanation:

The water will travel the fastest from a hot source. The reasons for this are several. The hot water is less dense, thus it is lighter. Being lighter makes it easier for the water to move, thus it reaches higher speeds. Also, the hot water is under higher pressure and has more energy in it that drives it, and that combined with the lesser density makes it faster. This can easily be noticed with the warm and cold ocean currents, with the warmer ones being faster slightly faster than the cold ones, as the cold ones require more energy to moved.

hot

Explanation:

hot

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

there are two significant figures.
