This question is difficult because you don't have a succinct definition for "Bread". If you make dough, and use liquids (milk, water, the water in eggs, etc.), then when you bake the bread, some of the water will evaporate. This will reduce the mass of the loaf of bread, because the water has gone elsewhere, but the water itself will retain their own mass. So yes -- when you bake bread, evaporation reduces the mass of the dough you started with.
The mass of the bread would not become more or less, but it would become more dense. "Density" refers to how close together the particles making up an object are grouped together.
Here's a very basic example to explain what I mean: Let's say that you got two plastic bags. They're the same exact size. If you put twenty marshmallows in each bag, they would have the exact same amount of "stuff" in them.
But if you took one bag and then smashed it in your fist, it would get a lot smaller than the other bag right? Well, the actual amount of marshmallows doesn't change does it? There are still twenty in each bag, so the mass doesn't change. But the marshmallows in the bag you crushed got packed very tightly together, so it is more dense.
Grams would work best for weighing a slice of bread.
A triple beam balance can measure the mass of one slice of bread.
There is about 130 mg of sodium in one slice of brown bread.
One slice of commercially prepared white bread contains 1 gram of fat.
Zero.
It depends on different brands approximately 250mg per slice white bread
That depends on how the bread is made. If you're purchasing bread from a store, look at the nutritional facts that are printed on the label
0.12 kg
there are 400 KJ in a slice of white bread!!! :D the answer above is total nonsense. there are 40 KJ in a slice of bread. most bread contain the same amount of kilojoules. this is the average amount in each slice of bread the first answer is around correct there are more than 40KJ in a saltana...
The bread will begin to absorb moisture, making it retain more weight.
everyone has slice of bread well.....not every one but i do have slices of bread!:-)
in one slice of the bread there would be over 90Kj
