∙ 10y agothe molecules do not change shape or size. they do not contract or expand only the object expand or contracts

∙ 11y agoThermal Expansion- When the temperature change is not very great a substance does not change it's state. The substances particles may only move faster and occupy and larger space.
Wiki User
∙ 14y agoSome examples of thermal expansion and contraction are when: water expand and contract and when the strings of a guitar expand and contract due to the heat caused by the stage lights.
Wiki User
∙ 9y agoThermal conduction refers to the expansion or contraction of materials due to thermal effects. Materials expand when they are heated, and contract when they are cooled.
Wiki User
∙ 14y agoYes.
Generally expand on heating, and contract on cooling.
Exception to this is H2O, smaller in liquid form than in solid.
Wiki User
∙ 11y agothe molecules become 'exited' when they heat up causing the to move around more. meaning that materials such as metal will expand

Why do railway lines have gaps in them?
to allow for the thermal expansion or contraction
Is thermal expansion and contraction a physical change?
Yes it is a physical change.
How does Thermal expansion and contraction affect dental waxes?
it expands and ur bf
Is it possible to save car mileage using the principle of thermal expansion and contraction?
No
What is a jar with its lid on tightly an example of?
Thermal expansion and contraction, specifically the different coefficients of thermal expansion (CTE) between glass and metal....AND ITS LIKE A (CLOSED SYSTEM)
What are jobs that require the use of thermal expansion and contraction?
Cement laying, for one job.
What type of changes occurs in thermal expansion and contraction?
These are physical changes. No new substance is produced.
What is thermal expansion and contraction of matter?
Thermal expansion will occur in just about all of the 15 or more phases of matter: whether it be solid, liquid, gas, etc.
Could expansion when a substance is heated or contraction when a substance is coooled cause problems?
Yes, the thermal expansion is very important in physics and technology.
What is thermal expension?
Thermal expansion is expension due to heat .When the molecule move faster in any object it is called thermal expension. Thermal contraction is when molecule contract in cold (low) temperature
What is a thermal actuator?
A thermal actuator is a mechanical system that uses thermally induced contraction and expansion of materials to create motion. It basically converts energy into motion.
How is heat related to expansion and contraction?
All energy is transferable. When a body contracts, gravitational potential energy is converted into both kinetic energy and thermal energy. Heat is released by contraction. Conversely, heat is used for expansion.
