which mass is larger, although they release the same amount of heat- steam or liquid water?

Answer 1

they dont give same amt. of heat...latent heat of steam is also involved
liquid water is more massive

Answer 2

Depends upon how you view 'mass' as the atoms of liquid water are the same mass-weight as the atoms of steam, just that stream is usually at a higher temperature.

Water 'vapor' on the other hand, can be equivalent to liquid water for Heat, so in that case the atoms themselves are still the same 'mass' - meaning "weight".

If you go for density, or occupation of space by mass or weight or atoms, the water vapor will occupy a larger volume of space for the same amount of mass-weight (atoms) content then the smaller 'puddle of water' the liquid will make.

Answer 3

liquid water mass is larger when compared to steam although they release same amount of heat
R;-. the molecules in water are more closely bonded than that in the steam because the molecules in the water gain K.E and move as steam

Answer 4

lets see: one molecule of water reacts with an equivalent amount of antimatter releasing all of its energy as heat. A billion tons of steam are disturbed by the gravitatinal field of a passing asteroid, releasing heat energy of 1E-999 ergs. Which is more massive...
I guess I missed the part where you describe the mechanism for the energy change.

Answer 5

mass have not related to heat releasing , steam and liquid water because other factors such as specific heat is important.

Answer 6

the liquid water is more massive given that they release same amount of heat.
