If the object is heated it will expand because the particles gain energy from the heat and move about more vigorously causing them to bump into each other and move further and further apart. When the substance is cooled (gets cold) the particles slow down and move closer and closer together causing the object to contract.

What is the difference between contraction and expansion?
In contraction the size of item becomes smaller. In contract, expansion increases it.
Air expansion and contraction?
expansion is when the air is HOT !
How do particles in a sound wave move?
The move by expansion and Contraction of the medium by which they are propagated. It is transmitted in air as a longitudinal wave- which means its direction is in line with the movement of the medium.
What does Expansion and contraction do to rocks?
strain them
What are some of the uses of expansion and contraction?
according to my research the thing for expansion and contraction are hot air balloons and a thermometer, there is also more.
Use the particle theory to explain the expansion and contraction of a solid when temperature is changed?
The expansion and contraction using particles is when a liquid melts because the particles get more energy and move around so making the substance appear less then there is and when the particles cool down they loose energy and move around slower so making them appear bigger than when they were warmer.
What is the antonym for contraction?
Expansion is the antonym for contraction.
What is the difference between contraction and expansion?
In contraction the size of item becomes smaller. In contract, expansion increases it.
What are the release dates for Expansion and Contraction - 1903?
Expansion and Contraction - 1903 was released on: USA: January 1903
Do you agree that expansion and contraction only cause problems?
No, we use expansion and contraction to tell temperature(thermometer).
Air expansion and contraction?
expansion is when the air is HOT !
What does an expansion tank do?
Allows for expansion and contraction of various systems
Why do railway lines have gaps in them?
to allow for the thermal expansion or contraction

What the opposite of Contraction?
The general opposite of contraction is expansion, or possibly inflation. For muscles, the opposite of contraction is relaxation.
