Will the jar contract or expand when heated?
Heat would cause the molecules to speed up movement and expand metals. Glass melts, paper burns, clay would shrink as water vapor escapes, etc.
How does temperature affect the volume of liquid?
Most liquids will expand when heated up.
When water is heated does it expand or contract?
No. The only change is the change from liquid to gas and all that happens is the particles in the water start to move faster and start to separate from one another. One particle is lighter than three and because it is hot it is less dense than air so it rises. :)
What happens to the liquid particles in a thermometer when it is heated?
They expand causing them to move in the only direction available, up the thermometer.
Why does the liquid expand in a thermometer when it gets hotter?
In a thermometer is a liquid metal called Mercury, so the liquid expands when it is heated up.
How does a bar of steel get shorter after it has cooled down?
The bar will contract (get shorter) as it cools down, and expand (get longer) as it is heated up.
Why does a gass expand when heated and contract when cooled?
When a gas is heated up, the particles within the gas start to move faster, going farther apart (expansion). When a gas is cooled, the particles slow down and it starts to condense (contract), and if cooled enough, into a liquid.

Does the chamber of a barometer expand or contract as the air pressure goes up?
EXPAND
What happens to most substances when they are heated?
They expand due to the molecules speeding up.
Why a glass jar can be easily opened if the metal lid is heated?
because metal will expand when it has been heated up
When metal heats up what will it do?
It will expand, and if heated enough, will start to glow and melt.
How does temperature affect the volume of liquid?
Most liquids will expand when heated up.
In addition to speeding up what will heated particles do?
expand and grow frow larger
How do expansion joints in a sidewalk keep the concrete from cracking?
The expansion joint in a sidewalk keeps the concrete from cracking just as what its called. It allows the concrete to expand when heated and contract when cold. Without the joint, the concrete will crack and become uneven or mountain up.
What is the purpose of a bridge?
Expansion joints. This allows the bridge to shift or the materials to expand and contract in the bridge. This means that if it gets heated up it expands so it needs a gap so it can move and not break the road!
What is thermal expansion and contraction?
when your feet go in shoes and then your feet expand and contract so your shoes will not fit.
