For a given substance, yes, it's gaseous form is hotter than its liquid form. However, you cannot say that a gas, of any substance, is generally hotter than a liquid of some other substance. Different substances have different boiling points. The boiling point for Nitrogen, for example, is well below the boiling point of water, and even below the freezing point of water. So you cannot say that Nitrogen gas is hotter than liquid water.
Not only liquids but also solids expand as they get hotter, with few exceptions.
NO, you will get hotter
Liquids have a definite volume but gas do not
Not necessarily. Both liquids and gases can exist over a wide range of temperatures.
This will depend upon the Thermos, but in general a thermos will keep hot liquids hotter for longer. This is because the Thermos has stronger insulating properties.
the answer is it gets it colder
A Flask
mixtures can be formed by physically putting two or more substances together. Mixtures can be formed between solids and liquids, solids and solids, liquids and liquids, solids and gas, liquids and gas, gas and gas
wood heaters are hotter
Liquids have the form of the containers.
yes
- Solutions can be saturated or unsaturated. or - Solutions of solids in liquids, solids in solids, liquids in liquids (rarely used the expression gas in gas).
