Merely heating a volume of water will only have a minuscule effect on the weight of the water.
Heating the water will however cause it to expand and thus have a lower density. (You have the same mass of water, but over a larger volume.)

What is lighter warm water with low salinity or cold water with high salinity?
Cold water with high salinity
If cold water sinks why is ice on top of pond?
Ice is lighter than the water it displaces .
What experiment could see if hot water evaporates faster than cold water?
Hot water need less energy to be evaporated than cold water.
Is it true cold water weighs more than hot water?
bcoz cold water has no vapours n hot water has hot water vapours which dries faster n bcomes lighter than cold water
A grade 8 science experiment involving kinetic molecular theory?
Hmm, experiment's concerning Kinetic Molecular Theory. Simple experiment's off the top of my head are a ballon, with a hot and cold water bath, observe the effects of temperature on volume. Another temperature vs. volume experiment (more like demonstration, if this is for the 8th grade) is: placing approximately 5mL of water in a empty soda can, heat on a hot plate until steam starts to form, using tongs place the can upside down in a pan of cold water, the gas inside the can cools and contracts thus decreasing the internal persure and making a satisfying implosion, you can experiment with heating times to get the coolest implosion (if the can stops steaming take off the hot plate, there is no more water!). Those are the two that I can think up right now. I'll ask my AP chem teacher to help.
Well a pencil folt longer in cold water or hot water?
i thank on cold it has lighter forse then hot i thank i dont know the right anwser
Why hot water dissolves food coloring faster than cold water?
I just did an experiment on this actually. Water molecules travel faster in hot water than in cold water. When food dye is added into hot water where the molecules are traveling faster, it mixes faster. In cold water, the particles are not traveling as fast and the food dye does not spread as fast.
Why doesn't cold dye rise into warm water?
Dose cold water weigh from hot water?
Cold water is weigh from hot water; as the molecules tend to free (or expand) by getting heat, which causes increase in specific volume (i.e. decrease in density). As a result, hot water becomes lighter, compared to cold.
What is a good conclusion for dissolving a alka seltzer tab in hot water cold water and tap water?
In this lab, i learned more about the experiment.
What plants grow the fastest in cold water or salt water?
I've tried this experiment and the results were that plants grow better in cold water because hot water just ruins the plant cycle and photosynthesis
Is does sugar dissolve faster in hot or cold water a good 6Th grade project?
Hot water. Hot water can also dissolve slightly more sugar than cold water can.
