no, because density is how heavy something is and just because a molecule is heated doesn't mean that it is heavier. ex. you get your chicken nuggets out of the fridge from the other night. then you put them in the microwave. you heat them up for 10 minutes. you take them out, do they seem heavier to you? try it... iv already tried it and the answer is no. glad i could help. :)

∙ 12y agoWhen air is heated, the density of it changes because the water in the air "vapors" are minimizing there for there heated air rises because it is not as heavy.
FootnoteIt depends on whether the air is in a a closed container or in an open or expandable container, like a piston. Density,ρ, is mass per unit volume.ρ=m/V
If the air is in a closed container that does not expand on heating then both the mass and the volume remain constant and so does the density. If the air is free to expand then on average the distance between molecules will increase and for a given volume there will be fewer molecules, i.e., the mass per unit volume will decrease and so will the density.

Does volume density or mass change when water is frozen then heated?
The density of water changes at different temperatures. As temperature goes up, density goes down.
Why do some substances change when they are heated or cooled?
A solid or liquid would not change in density because the volume would not change. The density of a gas would increase when cooled and decrease when heated provided the volume is allowed to change as a function of temperature. However, density of a gas is generally not measured because it is not a useful metric to use.* * * * *That is a rubbish answer.Almost all solids or liquids expand when heated. (Pure water under "normal" circumstances has an anomalous phase between 0 and 4 deg C). So heating will increase the volume thereby decrease the density.
If you poor out some of the water in a bucket does the remaining density of the water change?
If you poor out some of the water in a bucket does the density of water change?
When water is heated from 30 to 100 degree celsius what happened to its density?
Density decreases as expansion takes place when temperature increases.
What type of heat transfer is needed to change water in to water vapor?
The water must be heated.
How does the density of most substances change when they are heated?
generally, the density of a substance decreaces when heated, with the exception of ice, which is less dense than water.
Does volume density or mass change when water is frozen then heated?
The density of water changes at different temperatures. As temperature goes up, density goes down.
How does the volume and density of a substance change when it is heated?
The volume of a substance increases when heated, causing a decrease in density.
How does the temperature of water affect the speed at which an object sinks?
Yes. As water is heated above 4oC it expands. With this change in volume comes a change in density. Less density means less bouyant force on the object in the water.
How does density change?
Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.
Can you change waters density?
The density of liquid water is fairly constant across the range of temperatures. Liquid water is most dense at 4°C. At temperatures below that, water will expand slightly. When water freezes to form ice, it expands. Water vapor (steam) expands when heated.

Does the volume of water change the density of water?
Density = mass / volume. So if the volume changes, the density will obviously also change.

What happens to water at 4 degrees Celsius is heated slightly?
Its density decreases.
What happens to a sample water when it is heated between 4c and 100c?
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
When water gets heated what change may take place?
When water is heated a physical change may take place. The water may evaporate and become water vapor, but the chemical makeup of the water (H2O) will not change.
