When a load was added to the piston the volume of the liquid did not change but the volume of the air decreased Explain why this happened?

The particles in a liquid are very close together, so an increase in pressure cannot push them any closer. The particles in a gas are widely spaced, so they can easily be forced closer together. Gases are compressible, liquids are not.

Change of a liquid to a gas?
The change of a liquid to a gas is Vaporization. Not to be confused with "Evaporation".
What temperature change is needed to change a liquid into a solid?
it depends on what type of liquid it is
Is sublimation of naphthalene a physical or chemical change?
A liquid evaporating is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).-Alec Vasquez
Explain the differences in appearance and behaviour between liquid water and steam?
Steam and vapor are in the form of a gas. Liquid water is in the form of a liquid.
The physical change from one state of matter to another?
a phase change: solid to liquid: melting liquid to solid: freezing liquid to gas: vaporization gas to liquid: condensation solid to gas: sublimation gas to solid: deposition
What thing can change gas to liquid?
decreased heat, increased pressure
What is the change of state from gas to liquid called and explain why?
This process is called condensation.
What happens to snow molecules during phase change?
The snow (solid) become water (liquid); the distances between molecules are decreased during the change of phase.
What is happening to liquid evaporation in terms of bond and energy levels?
Evaporation is a phase change from liquid to gas, therefore it involves increased energy and decreased bonding on the molecular level.
When a liquid and its vapor are at equilibrium and pressure is suddenly decreased cooling occurs why?
Since the volume did not change, then a decrease in pressure has to change the temperature as well. The change in pressure decreased the kinetic motion and energy of the molecules, so the temperature correspondingly drops. This follows Gay-Lussac's Law where P1T2=P2T1
Bubbles begin to form in a sample of liquid but the temperature did not change What must happened to cause the change?
There may have been some gas in the liquid, or maybe there was a decrease in pressure.
What happen to the ices molecules during this phase change?
The ice (solid) become water (liquid); the distances between molecules are decreased during the change of phase, also the attraction forces.
Water does not have its own shape explain if?
the water or any liquid does not have its own shape because the water or liquid change their shape wherever you put. good luck
Explain why water freezing is not a chemical change.?
Because the chemical formula remain the same - liquid water or ice or vapour.
Is it a chemical or physical change when heat is put over sugar?
its physical change.to explain,the conversion of solid to liquid is physical
How can a boiling liquid boiling point can be decreased?
By reducing the ambient pressure.
Explain what causes the phase change when solid iron melts into liquid iron?
We are trying to study for our test, and this is one of the study questions?
