Warm water is best for yeast because yeast is a living organism that likes to live in similar temperatures to humans. Put yeast in hot water and it dies, put it in cold water and it will not do its job properly (will be too cold to reproduce fast etc). Put it in water that is just right and it will thrive

∙ 14y agoyeast needs hot water because yeast is alive, and apparently is has it's own reaction when you put yeast in hot water...

What are some reasons why people would want hot water or steam?
because when you are cold you need hot water to warm you up
Does salt and yeast inflate a balloon?
Live yeast can be used to inflate a balloon if you give the yeast something to ferment (such as sugar). They then produce carbon dioxide as a waste product that could inflate a balloon. You should not expect it to be buoyant, however, for CO2 is heavy as gases go (considerably heavier than air, for instance). The yeast cannot use salt for much of anything, however.
Why is no gas given off bt yeast mixed with suger and water at 100oC?
because the water is boiling and you have killed all the yeast.
What do yeast glucose and water result in?
The yeast will break down the glucose which produces Carbon dioxide + Ethanol + Energy during anaerobic respiration and the process is also known as 'fermentation'. Carbon dioxide and Ethanol are the waste products. During aerobic respiration, the yeast will produce the same products as we produce such as Carbon dioxide, water and energy.
What to use to test hot water?
It depends on how hot I want it to be. If I want regular out-of-the-tap hot water, I stick my finger in it quickly and then shout and wave my hand about when it's actually hot. If I need boiling water to be a certain temperature, I measure the temperature with a candying thermometer.
Will boiling water kill yeast?
Hot water kills yeast. If the water is to hot then the enzymes within the yeast will be denatured and unable to work. Instead warm water must be used to encourage 'growth'.
Will yeast activate with sugar if the water is too hot?
No, if the water is too hot, it can kill the yeast. The water needs to be between 90 and 110 degrees (F.)
Does hot water make yeast rise?
Warm, not hot, water will activate yeast causing them to produce carbon dioxide which causes breads to rise
Why does yeast grow in hot water?
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.
Are very hot liquids necessary to activate yeast?
Very hot liquids will kill off the yeast. Only use slightly warm water to activate the yeast.
What kind of liquid does yeast react best in?
hot water!
What are the states of matter when you add hot water to yeast?
aqeous
What is yeast an indicator of?
yeast is an indicator of sugar. it blows up (puffs up) when it is both put in hot water
Is yest alive?
yes yeast is alive when u add hot water
How warm should the water be when adding to yeast?
About 111 degrees is ideal...too hot and you may kill the little guys, too cold and the yeast wont proof
Can yeast be altered so it cannot produce a gas when sugar is available?
Yeast can be killed with heat, that is why you use warm water to start it, not hot.
Why must the sugar solution be cooled before adding yeast?
It's not clear in what context this question is asked, but hot water can kill yeast.
