Yes, no gas is given off, therefore the mass of conversation will stay the same.
matter
In chemical reactions the number of atoms stay the same no matter how they are arranged. So, their total mass stays the same.
The mass will always stay the same but the gravitational pull towards the centre of the earth (weight) will change.
After water has been boiled, its mass will stay the same.
mass mass
Your mass will stay the same. Mass is always the same no matter what.
Your mass will stay the same no matter where you go.
Yes
Density of the substance will always stay the same. Density of the object will also stay the same if solid, no matter the size, but not if it is carved out. That is why a steel boat can float
As the law of conservation of matter and mass dictates, matter can't be created or destroyed, only changed. The mass and the number of atoms always stay the same through a chemical reaction, just rearranged.
Your mass would stay the same. Mass is the amount of matter in an object, so your mass would stay at 68kg.
matter
no, your weight changes. your mass stays the same
In chemical reactions the number of atoms stay the same no matter how they are arranged. So, their total mass stays the same.
The most important thing is that mass is not the same as weight.Mass is the same everywhere in the universe; it refers to how much stuff a thing is made of.Weight is the measurement of gravity on an object. So when gravity changes, weight changes. However, mass will always stay the same.Weight will be less on the moon.Mass is the same no matter where the object is!
The mass will always stay the same but the gravitational pull towards the centre of the earth (weight) will change.
Yes. Outside very special experiments, matter (mass) can neither be created no destroyed.
