what happes to the density of a liquid when it heated?

Answer 1

the density of any substance is inversely proportional to the temperature...as the substance gets more and more heated the static energy of its molecules decrease and their kinetic energy increases...this reduces its density....when the kinetic energy of the molecule becomes higher than the force that binds the molecules together the molecule escapes the surface of he liquid, causing it to evaporate...the temperature at which this happens is called the boiling point of the substance....

Answer 2

Density represents the relationship between mass and volume. As particles are heated up, they are moving faster, and occupying a slightly larger volume of space as a result. The density of a substance goes down slightly as it is heated in the liquid phase.

Answer 3

liquids have a higher density than gas, so when liquid is heated, it will turn into a gas. The density will decrease. LET ME ASK YOU: is it harder to wave your hand in a pool of water or air? AIR. So gas has less density

Answer 4

the liquid expands and the density goes down.

Answer 5

Well... I believe it becomes less dense, but it also depends on what liquid you are working with.

For instance, liquid mercury in a thermometer becomes MUCH less dense when heated, while water does not show near as much of a difference.

Answer 6

as a liquid is heated it will expand in the ratio of the amount of heat absorbed,Remember it can only absorb so mutch heat then it makes a quantum leap to energy(ie light) then its gon in a flash if not enough heat then just plane old molecular migration occures,bummer.

Answer 7

Density goes down, and then it boils.

Answer 8

it goes down

Answer 9

stays the same
