How do pressure, density, state of matter, and temperature relate? these are my points, are they right?: 1. Higher temperature makes an object less dense 2. Density governs the state of matter for the object, hence as water becomes less and less dense, it becomes gas (water vapour) 3. Higher temperature makes an object has more pressure, hotter gas has higher pressure. 4. for pint 3, does it works backwards instead? i.e if a gas is pressured, it will be hotter. Thank you!
