Bread dough rises when yeast is added physical or chemical?
It IS chemical, but it's not a heat reaction. It's respiration. Yeast is a living organism, which consumes sugar and excretes CO2 and alcohol. - - - - - chemical, because its reacting with heat & that always means chemical. it just includes a physical change..
What makes bread rise and why?
Bread rises due to the action of yeast, which consumes sugars and produces carbon dioxide gas. The gas gets trapped in the dough, causing it to inflate and rise. This process is called fermentation and is what gives bread its airy texture.
Why does the temperature in a chemical reaction rise?
The temperature in a chemical reaction rises because energy is released as bonds are broken and formed between reactant molecules. This excess energy causes the surrounding molecules to move faster and increases the overall temperature of the system.
When water is boiled in a pot it bubbles Is this the result of a chemical reaction Explain why or why not?
The bubbling of water when boiled is not the result of a chemical reaction. It is due to the conversion of liquid water to water vapor, which forms bubbles as it rises to the surface. This process is physical in nature, involving the phase change from liquid to gas.
How does temperature affect the rate constant in a chemical reaction?
Temperature affects the rate constant in a chemical reaction by increasing it. As temperature rises, molecules move faster and collide more frequently, leading to a higher likelihood of successful reactions. This relationship is described by the Arrhenius equation, which shows that the rate constant is exponentially dependent on temperature.

Why is yeast important in alcoholic drinks?
In baking yeast is used typically as a leavening agent, meaning it causes the bread to rise. The yeast digests sugars from the bread dough and produces carbon dioxide, which raises the bread. In brewing, yeast serves two purposes: producing alcohol from the sugars in malt, and--in bottle or cask-conditioned beers--in carbonation. The yeast digests some of the sugars from the malt and produces alcohol and carbon dioxide (and various other molecules). During the fermentation process the carbon dioxide is the byproduct and is bled off to the atmosphere. For bottle-conditioned beers, the carbon dioxide from the yeast is forced into suspension in the liquid and causes the beer to be carbonated.
If steam escapes from a teapot is that chemical reaction explain please?
yes and no, it depends on what you would consider a chemical reaction. most people define a chemical reaction as when two or more chemicals react together, steam escaping from a pot, however, is not two chemicals, it is just water evaporating and condensing in the air to make steam which is hotter than air so it rises out of the pot, so it isn't a chemical reaction, so much as a 'change of chemical state'.
What evidence of a chemical reaction can be noticed when bread bakes?
When bread is baked, there are three main chemical reactions that take place. First, an elastic films develop, making the bread stretchy. Next, gases in the bread begin to expand, causing it to rise. Lastly, alcohol created by the yeast evaporates.
Why does the temperature in a chemical reaction rise?
The temperature in a chemical reaction rises because energy is released as bonds are broken and formed between reactant molecules. This excess energy causes the surrounding molecules to move faster and increases the overall temperature of the system.
Which long protein molecule in bread traps CO2 so that the bread rises?
Gluten.
When bread rises up what are in the wholes of the bread?
its bcuz air is enterning the bread..!! then it makes the bread rise and air bubbles or aka holes
When baking using baking soda what chemical reaction occurs when the batter rises before it sets?
It explodes like a volcano! It explodes like a volcano!
What is a chemical in which temperature increases during the reaction?
A chemical reaction in which the temperature increases is known as an exothermic reaction. During this type of reaction, energy is released in the form of heat as reactants are converted into products. Common examples include combustion reactions, such as burning wood or fossil fuels, where energy is released and the temperature rises. This heat release can be measured, indicating the reaction's exothermic nature.
