Is stale bread heavier than fresh bread?

Stale bread is NOT heavier than fresh bread. Stale bread is caused by age, light, and lack of moisture, none of which contribute to the bread's weight; if anything, they will cause the bread to lose weight, thanks to the loss of moisture. Even when bread gets moldy, it does not gain weight, since the molds consume the ingredients. My guess is that the asker is confusing weight with the hard feel of stale bread, which, BTW, is used in many recipes, including bread pudding, onion soup, etc. In other words, "stale" does not mean "bad".

Bread dough will probably be heavier than cooked bread because when it is cooked and heated it will lose water as it evaporates.

moisture is lost when the bread is toasted

No, bread takes longer to go stale when refrigerated. WRONG. Bread in fact becomes stale at a quickened rate once placed in the fridge. Why? ... retrogradation. Essentially the process of the starch molecules present slowly crystallizing. result ---> bread becomes stale nearly 6 times faster than room temp bread. Low temperatures slow down chemical reactions. So refridgerating the bread will stave of bacteria longer, but will make it stale faster, b/c crystallization is a physical change.

Because the in the egg have a life

They will go stale alot faster than plan old loaf bread.

Within hours. Same with cookies. If you leave a sandwich out in room temperature for a few hours. It will be stale when you go to eat it. The amount of time varies with the temperature and humidity of the room. A humid room will stale bread slower than in a drier, cooler room.

Salt water is different because it is heavier than fresh water.

because the salt water ie heavier than fresh water

Bread enclosed in a moisture proof bag can go moldy faster than out in the air or in a breathable bag, however bread exposed to air does dry out.

I'd imagine that everyone would rather, eat fresh, more than stale food. Fresh foods are more healthier.

yes, for about 2-3 more weeks than putting your bread in a freezer

Yes, it is the reason is the salinity in the salt water makes it heavier. It makes it so heavy that it sinks and the fresh water gets pushed to the top

gold is measured 14 ounces to a pound bread is measured 16 ounces to a pound

yes It is because the toast has lost its water by being dried(toasted).

Fresh bread gets moldy because it is not full of the preservatives that bread in a bag contains. Wet or moist bread obviously molds faster than dry bread,

I believe that if you keep bread in the freezer, it will last longer than if it was at room temperature or if it was in the fridge.

The question is difficult to answer. Thicker bread slices will be heavier than thinner slices off the same type if bread, Different types of bread of the same slice thickness, such as white bread, whole grain bread, will not have the same weight.

Yes! We tried it in the classroom today with an equal substitution amount and the bread was a little heavier than normal, but still wonderful!

Bread will never be as fresh as the day it is made. To keep bread "fresh" for more than a day, preservatives and dough conditioners will be needed. Shelf life will depend upon several things, including: the formulation, quality of ingredients, processing conditions, handling, and storage. Unless the bread becomes moldy, it can be safe to eat even when it dries out.

Bread freezes quite well, and defrosts quickly, so freezing is a good way to keep bread fresh longer than if it is left out at room temperature.

Because salt water can carry more objects than fresh water because the salt in the water makes the water heavier, and because fresh water has nothing in it so it's less heavier. Water cannot carry something heavier than itself. This heaviness is called density, and is the mass of the water in a particular volume of water. Pure fresh water has a density of 1g/mL, which means each milliliter of water has a mass of 1 gram. Anything that has a density greater than 1g/mL will sink in fresh water. The density of salt water is greater than 1g/mL, so anything that has a density less than the salt water will float on it, including fresh water.

It is a simile as it is describing the joke as last week's breakfast rather than saying it 'is' last weeks brekfast

Yes, assuming you're talking about a mixture of fresh water and salt water. The salt water is heavier than the fresh water and would therefore sink.

no, protons are heavier than neutrons and electrons, but the nucleus is heavier than protons.
