Answer :
The key differences between a liquid and the a gas is,
A liquid has no fixed shape but it has a volume.
A gas has neither a fixed shape nor a volume.
A liquid has more inter-molecular space between the molecules.
A gas has larger inter-molecular space between the molecules as compared to the liquids.
- Inter-molecular attraction :
A liquid has some Inter-molecular attraction between the molecules because of the low Inter-molecular spacing between the molecules.
A gas has very low or minimum Inter-molecular attraction between the molecules because of the larger Inter-molecular spacing between the molecules.
A liquid flow from the higher to the lower region but a gas flow in all the direction.

Explanation:
9g of water contains : 9g/18 g/mol = 0.5 mole of water
1) 2 moles of hydrogen yields 2 moles of water
x moles of hydrogen yields 0.5 moles of water
x= 2 × 0.5/2 = 0.5 moles of hydrogen
Mass of hydrogen = 0.5 moles × 2 = 1 g of hydrogen
2) Number of moles of Al(OH)3 = 468 g/ 78 g/mol = 6 moles
2 moles of Al(OH)3 yields 3 moles of H2O
6 moles of Al(OH)3 yields 6 × 3/2 = 9 moles of H20
Mass of water =9 moles × 18 g/mol = 162 g of water
3) There are 13 oxygen atoms in the compound.
Mass of each oxygen atom = 16 g
Total mass of oxygen atoms = 13 × 16 = 208 g
The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
