The warm water would help to activate the yeast necessary for the bread to rise.
Bread rises from having yeast react to warm water and eat up sugars in which causes bubbling in which makes bread rise. :D
If the water is too hot, it kills the yeast. It stops working and therefore wouldn't make the bread rise. If the water was too cold, it wouldn't do anything to the bread. If you use warm water, however, then it gives enough energy to help the yeast work so that the bread can rise, making you're loaf.
if there is no yeast in the bread the bread will not rise
because the yeast reacts to heat.
The microbe in bread is yeast. Yeast is a living substance and it is useful in bread because it respires and creates bubbles that makes the bread rise. this happens when the bread dough is left in a warm area to rise. The yeast also makes alcohol during this proses but this evaporates when the bread is cooked. the cooking proses also kills the yeast.
Because bread is supposed to be kind of sweet, and might taste sour if you don't add sugar. Also it helps the bread rise when mixed with the yeast and warm water.
The warm water makes the yeast (balm) to increase more rapidly. So improving the rate that the bread dough will rise.
Bread that uses yeast to rise (not "quickbreads") will only rise at a temperature that supports the life and growth of the yeast. This is about the temperature of a very warm room. When bread reaches oven temperature the yeast is killed, so the main rising of the bread is done before baking. Any further rising in the oven happens before the bread gets heated through, or from the expansion of the bubbles that were already in the bread.
To 'prove' your bread means to allow the yeast time to work and raise the dough, to do this cover your dough with a damp tea towel and put it in a warm place for 30 to 40 mins.
Yes, but you have to let it warm to room temperature and rise before baking.
Bread needs to rise, because inside the bread is lots of Carbon Dioxide, so the bread needs to rise to let out all the Carbon Dioxide.
