The ideal temperature for yeast growth is 100 to 115 degrees F, but for leavening purposes, the ideal temperature is 80 to 95 degrees F. If the yeast grows too quickly, it will produce large bubble pockets in the bread.
Yeast begins to die at 120 degrees F. So it's important to let your yeast dough rise in a spot where the temperature is stable.
The cooler the temperature, the slower the yeast grows. It will grow in the refrigerator, but very slowly. I don't know the minimum temperature for it to grow.

What is the temperature of a yeast environment?
The temperature of a yeast environment will have to be at 100 degrees Fahrenheit. Warmer temperatures will start to kill off the yeast, while colder temperatures will make it go dormant.
How does the temperature of water affect the growth of yeast?
Yeast need warm temperatures in order to grow. The perfect temperature for yeast is about 110 degrees F. Yeast will not start to reproduce and rise without warm temperatures to activate it.
How does temperature affect reparation rate of yeast?
Yeast does different things based on temperature.
What if the yeast is not working in brewing beer?
There are several reasons this could happen: # The yeast was dead to begin with. # Something is wrong with the conditions for the yeast (temperature, infection, pollution). # The yeast was under pitched and is growing so slowly you can't tell. The solution to numbers 1 and 3 is to re-pitch the yeast as soon as it's apparent that the yeast is not growing. You'll want to use a starter if possible to give the yeast a good head start over any potential infection in the brew. The solution to number 2 is to correct any environmental problems (like temperature) and re-pitch the yeast as needed. If the problem is infection or pollution, however, the batch of beer is basically done for. You may not find this out until the re-pitched yeast also fails to grow. Yeast storage problems are usually the cause of number 1. Be sure to keep liquid yeast packets refrigerated until hours before they are ready to be used.
Why doesn't yeast rise in hot or cold temperatures?
If the temperature is too low, the yeast will remain dormant. If the temperature becomes too hot, the yeast organisms will be overwhelmed and killed before they can respire.
Does temperature affect yeast growth?
Yes.
Is there yeast in coolers?
No, especially not if the cooler is cool. Yeast survives and reproduces "with an optimal temperature range of 30°-37°C (86°-98.6°F)" (http://en.wikipedia.org/wiki/Yeast). Any temperature significantly above or below this will not allow yeast to survive.
What is one relationship between temperature and rate of gas production in yeast?
There is a direct proportional relationship between temperature and rate of gas production in yeast. The higher the temperature the more gas will be produced.
Coolant level is ok but the temperature light is on when cold start?
Answer: My brilliant cousin reckons when you first turn the key on and start it up, it just tests whether the temperature light is working.
Does yeast ferment better at room temperature or in a warmer temperature?
Yeast needs a warm temperature to grow. The best temperature for proofing the yeast and rising the bread (or other yeast baked foods) is about 110 degrees Fahrenheit. If it's too hot, it will kill the yeast, and if it's too cold, it will retard or prevent the yeast from growing.
What is the optimal temperature for yeast to ferment and metabolise?
Room Temperature (26o - 28o C)
Why is it important that catalytic converters start working at as low temperature as possible?
The quicker they are functioning, the lower the emissions will be.
