Interpretation:
Matter
(Physical substance in general which occupies space and possesses rest mass)
Solid | Liquid | Gas |
(1) A solid is a sample of matter that retains its shape and density when not confined. (2) Strong molecular force of attraction exist between atoms ions molecules. |
(1) A liquid is a sample of matter that conforms to shape of container in which it is held and which acquires a defined surface in the presence of gravity. (2) Weak molecular force of attraction exists between atoms/ions/molecule. |
(1) A gas is a sample of matter that conforms to the shape of container in which it is placed and acquire whole volume of container. (2) Negligible force of attraction exists between atoms/ion/molecules. |
Concept Introduction:
Physical change: physical change occurs when a substance alters its state , but does not change its chemical composition.
State of matter depends upon temperature and pressure. As temperature or pressure or both change then state of matter may also change.
Phase change: transition of a substance from one state to another state
Phase: it is defined as a homogenous portion of a system that has uniform physical and chemical characteristic.
Draw initial temperature and pressure on phase diagram identify the initial phase similarly draw final temperature and pressure on phase diagram identify the final phase. After that you can decide which phase transition occurs.
To determine:
A sample of the substance in this phase diagram is initially at and . Which phase transition occurs when the pressure is decreased to at constant temperature?
Solid to liquid.
Liquid to gas.
Solid to gas.
Liquid to solid.
