What
Probably, but not to the point you would care
yes, duh
colder water is denser and thus heavier
but only until 4 degrees
after that it begins to become less dense again
Depends on what you’re comparing it to, and the various factors that contribute to the weight of two things.
If you mean the same single bottle of water, with different temperatures. Then no.
It quite literally wouldn’t weigh any different.
Also don't question why i'm wide away at 4:20 AMdeuterium water heavier
you’re not wrong
tritium water 
salt water 
monster energy
Flint water
tap water
yoshi8me water
prepare for my nerd moment
hot water would be heavier cause e=mc^2 meaning energy = mass. heat is energy so more heat = more mass
therefore hot water would be ever so slightly heavier, just a sliver
I don’t think more energy=more mass
if you converted it all into mass it would technically have more mass but upon rethinking it it wouldn’t immediately have more mass just more mass/energy
but it isn’t converted to mass bro
broski missed my whole point

you can’t replace the letter o with the word bait bro
After a quick google search, I have learned the following:
An object’s density is affected. Basically, it becomes more like gas as it heats up, causing the mass to spread out. This means that no, if you cool a set amount of mass, it will not gain or lose weight—provided that none of the mass is removed from the object (nothing evaporates, basically).
water specifically would be most dense in liquid form, its unique crystal structure makes ice spread out and gas is naturally less dense than liquid
