Gas. Because the molecules/atoms are free moving
less dense than the solid material around it
No, Hydrogen gas is less dense than Helium gas.
low pressure. because warm air is less dense. so it's pressure is also low.( less dense because because of the heat( warm air = hot air) the molecules of the air is very active. so the the are not close to each other which means less dense)
placer deposits from where water is moving fast enough to move lighter materials.
Gas. Because the molecules/atoms are free moving
because it is dense
Hot air is "light" (less dense) because the atoms of the gas are moving faster
Moving a blade through a dense material like wood creates friction . Friction creates heat.

Solid. Because it's more dense.
No because the warmer oil's molicules are moving at a faster rate there for makeing the oil less dense
It doesn't, sound travels faster through wood. The more dense the material the better the sound carries. Because wood is more dense than a gas such as oxygen the sound travles faster through the wood.
less dense than the solid material around it
A stone sinks in water because it is more dense than water.
because glass is more dense, meaning the particles are more tightly together, because its a solid. sound travles fastest through gas because gases arnt very dense, their particles arent so tightly put together, so its easier for the sound waves to get through
