What has to be overcome for a solid to change to a liquid and a liquid to a gas?
The energy between particles. The particles must be heated so that there is no forces of attraction, therefore the solids particles can loosen into liquid particles and the liquids particles can loosen into gas, the heat energy is used to make the particles move faster
What keep the particles of a liquid from spreading out to fill an entire container in the same way that gas particles do?
In a liquid, the particles are in constant motion but are still close enough to each other to maintain some level of attraction. The intermolecular forces in a liquid (such as van der Waals forces or hydrogen bonding) prevent the particles from spreading out as much as gas particles, which have weaker intermolecular forces. This is why liquids have a definite volume and take the shape of their container, but not to the extent of gases.
Does The meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid?
Yes, the meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid. The meniscus forms due to the cohesion between water molecules and adhesion with the test tube, which is a result of intermolecular forces acting uniformly on all water molecules at the surface.
Why a liquid retains its volume but a gas has no definite volume?
In a liquid, the particles are close together and have strong intermolecular forces that hold them in fixed positions, allowing the liquid to retain its volume. In a gas, the particles are far apart and have weak intermolecular forces, causing them to move freely and fill the entire container, resulting in no definite volume.
How do intermolecular forces determine a substance's state?
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
What causes liquid and gas?
Liquid and gas are caused by the kinetic energy of the particles within a substance. In a liquid, the particles have enough energy to move past each other but are still held together by intermolecular forces. In a gas, the particles have even more energy and move freely, with very weak intermolecular forces.

Why liquid particles did not join to the solid particle?
Liquid particles did not join to the solid particle because the forces holding the liquid particles together were greater than the forces attracting them to the solid particle. This is due to a combination of factors including surface tension, intermolecular forces, and the relative energy levels of the particles involved.
What types of of forces exists between particles of a liquid?
week atrative forces
How does the strength of liquids intermolecular forces affect its viscosity?
liquid's particles are not as close as to that of the solid the very reason why it cannot be held.because of this ability of liquid to flow, it affects the forces of a liquid to flow thoroughly.
Why do particles move more freely in a gas than in a liquid?
Particles in a gas have more kinetic energy than in a liquid, allowing them to move more freely and quickly. In a gas, particles are far apart and experience weak intermolecular forces, while in a liquid, particles are closer together and experience stronger intermolecular forces, restricting their movement.
Does The meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid?
Yes, the meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid. The meniscus forms due to the cohesion between water molecules and adhesion with the test tube, which is a result of intermolecular forces acting uniformly on all water molecules at the surface.
Where does all the heat energy go when boiling?
When a liquid is boiling, the heat energy is used to break the intermolecular forces holding the liquid particles together. This energy is then converted into potential energy to enable the liquid particles to overcome these forces and transition into the gaseous state.
What keeps the particles of a liquid from spreading out to fill an entire container in the same way that gas particles do?
The particles of a liquid are attracted to each other through intermolecular forces, which keeps them close together and prevents them from spreading out as freely as gas particles. The stronger intermolecular forces in liquids compared to gases allow them to maintain a closer arrangement, leading to a fixed volume and shape.
Are intermolecular forces stronger in liquids or gases?
Intermolecular forces are stronger in liquids than in gases. A gas is the physical state characterized by the complete dominance of kinetic energy (disruptive forces) over potential energy (cohesive forces). Thus, gas particles move independently of one another. On the other hand, a liquid is the physical state characterized by potential energy (cohesive forces) and kinetic energy (disruptive forces) of about the same magnitude. So, the particles in the liquid have enough kinetic energy to move and slide past one another, but are still held together by any intermolecular forces. The particles in the liquid will break free of any intermolecular bonds once they obtain enough kinetic energy.
Why a liquid retains its volume but a gas has no definite volume?
In a liquid, the particles are close together and have strong intermolecular forces that hold them in fixed positions, allowing the liquid to retain its volume. In a gas, the particles are far apart and have weak intermolecular forces, causing them to move freely and fill the entire container, resulting in no definite volume.
