Do water pipes in homes expand and contract?
Well if water is too cold, pipes will contract and if water is too hot, the pipes will expand.
Does glass expand or contract when heated?
Glass definitely contracts when cooled. If you take a hot glass bottle, perhaps one that has been sitting by a campfire, and toss it into cold water, perhaps a nearby river, you will almost certainly find that the glass fractures as the surface in contact with the cold water tries to contract while the inner glass that is still hot does not.
Why do things shrink when it is cold?
Because most things, such as metals, expand when hot. So cold does the opposite.
Does hot water in a plastic bottle causes it to expand?
Not necessarily. You have to have a space of air in the bottle. The expansion/contraction happens because the water is heating/cooling the air. Liquids are usually considered incompressible and hence will not change their volume when heated or cooled (unless it evaporates or melts!). Assuming that you have an air space: If you have cold water in a sealed bottle that you heat up, it will expand. If you put hot water in a bottle and seal it, it will contract as it cools. If the bottle is not sealed, there will be no volume change.
Why do object expand?
Objects contract or expand depending on the temperature. Cold makes things contract, heat makes things expand. However, there are some exceptions. For example, water expands when it turns to ice. This is due to the process of crystallization. The reason that objects expand and contract is found at the atomic level. When an object is warm, its molecules move faster and spread out, making that object expand. However, when an object is cold, the atoms slow down and move back together, making the object contract.

What temperature does steel expand?
0.00000645in/in/deg F is the coefficient of expansion for steel. so if you had a 12" plate, that was heated up 30°f you would get "0.00000645 * 12 * 30 = 0.002322" (12" + 0.002322") would be the new length at the increased temperature.

Why does caps on a jar unscrew when it gets warm?
Because capsare made of metals, and when metals get hot they expand, making it bigger, and easier to unscrew
Why does hot water continually run into the expansion tank?
Because it likes a place to expand and contract
Why do telephone lines hang lower on a hot day?
metals expand when they get warmer which makes the cables longer.

Why an inflated balloon expand in warmwater?
Actually, it should decrease in size. The volume of a gas is directly proportional to the temperature of a gas (measured in Kelvin). Therefore if you inflate a balloon with your warm breath and then cool it down with cold water, the balloon will shrink, not increase in size.See the Related Questions for more information about the effect of temperature on gases.
Why do telephone wires become loose and sag in winter?
They shouldn't, usually it is the other way around. As with all wire, the temperature effects wire lengths. When wires become warm as in a hot summer day the wires expand and droop and likewise when they become cold as in winter they contract and tighten up. The wires have to be installed to take this condition into consideration. There is a specific engineered sag allowed for each type of conductor from pole fix point to pole fix point.

Why does a sugar cube dissolve better in hotter water?
all things are made of molecules, when molecules are hot or warm, they expand quicker, when they are cooled they tend to clump together.
