Why does gas have a larger volume than liquid?
Molecules within gases are further apart and weakly attracted to each other. Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
Does gas have a greater volume?
Gas � In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other….Liquids Solids and Gases:
| Definite shape | definite volume | |
|---|---|---|
| gas | no | no |
How does the volume of water as a gas differ from that of the liquid?
Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Why does gas have a definite volume?
A gas has neither a definite shape nor a definite volume. Like liquids, gases are fluids. The particles in a gas can move around one another freely. If a gas is released in a closed container, the gas particles will move in all directions and spread apart as they fill the container.
Does gas have more matter than liquid?
If you have the same number of particles, then the gas will have the greater volume. The particles of matter in the liquid state are still close together but they are far enough apart to move freely. The particles of matter in the gaseous state are neither close together nor fixed in place.
Does gas have higher density than liquid?
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases.
Why gases have less mass than solid and liquid?
This is because the particles are tightly packed in both states. The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume . This means the gas is less dense.
Which is a larger volume liquid or gas?
The particles of matter in the liquid state are still close together but they are far enough apart to move freely. The particles of matter in the gaseous state are neither close together nor fixed in place. The gas expands to fill its container. Thus, a given number of particles will have the greatest volume in the gas state.
Why does volume increase when we add more gas molecules?
Why does volume increase when we add more gas molecules? As more and more gas molecules collide with the walls of their container, they build pressure inside the container. To reduce this pressure, the volume of gas must increase. Once the gas volume increase, gas molecules must travel longer distances to strike the walls of their container.
Why is hydrogen gas volume double the amount of oxygen?
Because the number of mols of hydrogen resulted from the electrolysis is always double, and each mol of gas occupies the same volume (1 mol of gas = 22,4 l in STP) 2H2O—-> 2H2 + O2. 2 mol H2O => 2 mol H2 + 1 mol O2 = 44.8 L H2 + 22.4 l O2.
How are gas molecules different from liquid molecules?
Gas molecules have very high intermolecular distances as compared to liquids. Due to larger intermolecular distances, the binding energy of gases is also less, as also the excitation band width. Moreover, larger density liquid will have more no. of molecules in a finite space than smaller density gas.
