The heat provides energy for the enzymes in the yeast to work. If the water is to hot however, the enzymes will be denatured, and the yeast will not grow.

Does yeast grow in water?
The little brown grains of dried yeast (from the packet) can and will grow if put into water (at room temperature) with a little bit of sugar dissolved in it. You will see them growing because the water will begin to produce a foam after 30 mins. However, please note that if the dried yeast is kept too long before it is used, then the yeast in the brown grains may be killed. In this case no foam will be produced.
