A cookbook says that yeast works most quickly with water at a temperature of 20 c to 30 c?

At low temperatures (0-10 C) yeast will not grow, but not die either. At temperatures 10-37 C yeast will grow and multiply, faster at higher temperatures with an optimal growth at 30 or 37 C (that depends on the species). At higher temperature the cells become stressed, meaning that their content becomes damaged and which can be repaired to some degree. At high temperatures (>50 C) the cells die.

∙ 14y agoWarmer temperatures cause an increase in the rate of chemical reactions, including the chemical reactions in cells. However, if the temperature gets too high, it can kill the cells. These two effects combine so that 20-30 oC is the ideal range (presumably; I don't know much about cooking, just about chemistry).

How does evaperation work?
Evaporate comes from latin "ex", meaning out, and "vapor", meaning steam. The suffix "ate" is there to signify an action. Evaporation works like this. Water is heated to a temperature where it turns into a gas. This gas is then expelled out and up into the atmosphere.

How does a Crofton Electric Water Kettle work?
There is a heating element in the kettle. As the water boils, the inner temperature of the kettle rises. Once the boiling temperature is reached, a small thermostat is triggered which turns the kettle off, so as to not boil continually. This thermostat works optimally with the lid on the kettle fully closed, if the lid is not fully closed, it does not switch the kettle off as quickly.
Why is Water Boiling in radiator?
The water is boiling in radiator because it's temperature(radiator's) reaches the boiling point of water when the engine works for a long time.
What do you do about heartburn on the hcg diet?
Take a teaspoon of baking soda with 6 oz of water --- tastes chalky but works quickly
When you add sugar to the boiling hot water the temperature is increased decreased or stayed the same?
The temperature of the boiling water would be decreased for a short time due to the temperature of the sugar being at room temperature. If you have ever made a batch of jam you can see how it works. The initial 'jam' solution is brought to a rolling boil [a boil which cannot be stirred down], then the sugar is added and quickly stirred in. The 'jam' returns to it's non-boiling state for about 2-3 minutes before it returns to a rolling boil.
At what temperature does osmosis work best?
I think that the osmosis works best at higher temperature. At higher temperature, the water molecules will have more kinetic energy and move faster thus increasing the process of osmosis.
