Answer:

The mass of a substance is constant according to the law of conservation of mass.

Explanation:

According to the law of conservation of mass, matter can never be created or destroyed in a chemical reaction, even though it may undergo change from one physical state to another.

This means that in an isolated or closed system, the mass of matter will always be the same irrespective of the type of change that matter undergoes. This is so because, the mass of a substance is a measure of the quantity of matter in that substance and is constant. The number of particles does not change during a change of state, only their spacing and arrangement. In solid ammonia, the particles are more compact and arranged, whereas in gaseous ammonia, they are more randomly spaced out.

Why do you think molds are not growing all over everything around you?
Olegator [25]

Because:

Not everything around you has the correct moisture to grow mold. Places like a shower, wood, and even toilets do, since water will soak into them, or the water is trapped. If you don't clean your shower and toilet, you will notice mold. If you look at a fence, there is probably hints of mold on it.

Something like a shelf cannot grow mold, since it usually has paint on it, and the moisture won't go through something like paint.

Another possible answer: Since the areas around you don't always have the correct moisture, mold will not grow on everything. It can grow on some stuff in your house, but not everything around you.
