LINEAR EXPANSION OF BODIES

Linear expansion is basically the____________ in length of a material in relation to the increase of the temperature of the material.

• decrease

• loss

• increase

• expansion

Linear expansion coefficients for most materials variates with _______________.

• length

• heat

• matter

• temperature

 $dl=L_{0\ \ }α\ (t_1-t_0)$  What does "a" means in this linear thermal expansion?

• linear expansion coefficient

•  final temperature 

• initial length of object 

• hange in object length 

Is the tendency of matter to change its shape, area, and volume in response to a change in temperature.

• Heat

• Kinetic energy

• Temperature

• Thermal expansion

The flow of energy between to systems by Kinetic energy.

The _______________ use the linear expansion of bodies when the red liquid that marks the temperature goes up when it is hot, and goes down when it is cold.

Does matter usually expand when its heated?

• Depends on the volume of the particles

• Yes, maybe it does because of matter

• Depends on the typical particle-particle potential in matter
