How does heat lift objects?
I'm not a physics expert, but this is more or less my understanding of what happens: Heating an object means that the individual atoms that make up the object move around faster. As they move around faster they collide with each other more often and more energetically. This makes the atoms recoil from each other and therefore in general, all the atoms in the obejct end up beign further apart from each other. This makes the object expand. As it exands, it becomes less dense and therefore less heavy. A classic example is a hot air balloon. The air inside the ballon is heated and expands, becomes less dense and therefore lighter than the air outside the balloon eventually resulting in the ballon raising off the ground - esssentially the lighter air inside the balloon floats up through the cold denser / heavier air outside the balloon - same way as a plastic bottle full of air will float in water - air is lighter / less dense than water - hot air is lighter / less dense than cold air.
Solids are generally heavy while gases are light explain?
Solids tend to be heavier because they have more atoms in less area (density) and the reason they have more atoms in less area is because they have an atomic attraction between them that is much greater than that of gasses and liquids (liquids have no atomic attraction and gasses tend to repel themselves) Now gasses whose atoms repel against themselves are much more disperse and occupy a lot more space with a lot less mass.

What do moleclues and atoms have in common?
Molecules are formed with bonds between either atoms or ions, which are just charged atoms (more or less electrons than protons). (:
Is ozone more soluble in cold or hot water?
Ozone is more soluble in hot water than cold water. This is due to the rate at which the atoms and molecules are moving around.
Is cold water more or less dense than warm water?
cold ocean waer has more dense than warm water.
Is the mass of an object more less when it is hot?
It would stay the same unless some atoms escaped.
What is more dense a cold object or a hot object?
A cold object is more dense.
How does temperature increase or decrease?
Temperature is the average Kinetic energy of molecules in an object. A hot object has more kinetic energy and a cold object has less kinetic energy.
What do dinosaurs have in common with atoms?
Dinosaurs were made up of atoms. Every single object is made up of atoms only. Incidentally most of the animals have same atom in their body. They are there in more or less quantity.
How does heating affect an object?
The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)
What determines if an object will sink or float in water?
If an object's density (how uch mass/molecules/atoms it has in any given volume) is more than that of water, than it sinks; less, then it floats.
What does cold water have in it?
Water has the same components at any temperature, hot to cold. The reason cold water is cold is because it has less heat (the atoms of water are moving more slowly than at higher temperatures). the colder the water is, the slower its atoms are moving. So, the difference is heat, not what's in it (its composition).
If you raise the temperature what happens to an object's density?
The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)
What has more energy hot or cold water?
Hot because the atoms in the water are moving much faster then the atoms in cold water.
Which has higher density cold air or warm air?
The cold air is denser, because the cold atoms are thicker, denser, and have more mass. Warm atoms are less dense and move more, therefore creating heat.

A solids structure is?
Well in every object there are atoms and they're always moving and in a solid they are more squished together and are moving less than when in a gas or liquid form the more condense area is stable giving the streng to support anthor object.
