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. :)
Do wires expand?
Yes, wires can expand when heated and contract when cooled. This is due to the thermal expansion and contraction properties of the material that the wire is made of. It's important to consider this factor when designing electrical systems to prevent damage or malfunctions.
Why is thermal expansion not visible in solids?
Thermal expansion in solids is normally very small - typically around one part in one hundred thousand for a one Kelvin temperature change. That means that a one metre long length of aluminium, for example, will only change size by 0.23mm when heated by 10kelvin - effectively invisible to the human eye. Thermal expansion, though can be visible to the unaided eye if the object is large enough - a kilometer long bridge, for example, may vary in length by as much as a metre or more between summer and winter, depending upon the seasonal temperature change, and will have expansion joints that allow sections of the bridge to expand into one another without changing the overall length of the bridge, and risking damage to the structure. If you were to look at these joints in winter and then in summer, you would see the difference that thermal expansion makes.
What will happen if a partially inflated party balloon were heated?
The air molecules would expand, increasing the pressure of the balloon. When anything gets cold, it contracts, and when heated, it expands. Atoms and molecules are always moving - when something is hot, the molecules are moving faster and greater distances. When something is cold, the molecules are still moving, just slowly and at much smaller distances. You won't see much a difference while it's partially inflated, though there would be one. You can see results more drastically by heating a balloon that is near completely inflated. The more air molecules that are in the balloon, the greater the expansion. In other words, the bigger the balloon and more air that's in it, when heated you will see a larger change in the balloon size.
Are particles closer together in solids or gases?
I think solids... I'm not 100 % sure though.
Do most solids expand when cooled?
No, most solids contract when cooled, as the lower temperature causes the atoms or molecules to move less, leading to a decrease in volume. However, there are exceptions, such as water, which expands when cooled below 4°C before turning into ice.
Does heated water expand?
i believe heat does expand... I'm not sure though. i think the particles separate to have room to vibrate. that causes the heat to expand. :)

Does particles in gases expand when heated?
This is because when heat is applied to particles, they gain energy, therefore they travel faster and space out. The volume will increase though the density will decrease. So matter will always expand when exposed to heat.

When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place?
The change that takes place when sugar is heated to form a thick, colorless liquid substance is a physical change. This is because the molecular structure of the sugar remains the same even though its physical state has changed from solid to liquid.
Is white powder an element when it is heated?
The temperature of a substance does not change whether it is an element or a compound, though some substances will react when heated. White powder is not any particular substance. There are many substances that can come in the form of a white powders, but the only one that is an element is phosphorus. All the rest are compounds, though some of those may break down into their base elements when heated.

Is it true that sound travels through solids but not though liquids and gases?
secret
How do you expand rooms on Webkinz?
You cannot expand the rooms of your Webkinz house. You can buy larger rooms to add to your house though.
Can light waves travel though solids?
Light can propagate through some solids, but not all. Some transparent solids: Ice, glass, clear plastic, quartz, diamond Some opaque solids: Rock, wood, copper, gold, meat-loaf
Why must beaker cooled before adding watrer?
Glass expands when heated and contracts when cooled; however, if it is cooled or heated too quickly, it is likely that it will not contract or expand at a uniform rate, and this produces stress in parts of the glass, which can cause it to crack or even explode if the temperature change is even more abrupt. Because of this, lab glassware is often made of boron silicate glass, which is much more resistant to abrupt temperature changes than regular glass. Keep in mind though, that it is still vulnerable to the previously stated effect, though less than regular glass.
