the particles get more energy from the heat so they move more and take up more space

How does volume affect temperature?
Normally there is no affect. In a gas, a CHANGE of volume of a single body, will give a change in temperature. If a gas is compressed the temperature will increase. If a gas is allowed to expand, there will be a reduction in temperature. This principle is used in diesel engines, to ignite the fuel by compression and fridges, where an expansion of gas causes cooling.
When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
Does water expand when getting warmer?
It depends on the temperure of the water. Water actually reaches maximum density at 4 degrees centigrade. It expands or gets less dense as it increases in temperature above that.
What substance does not expand on heating?
For example pure silicon doesn't expand in a given range of temperature. Also a mixture of amorphous and crystalline quartz has a thermal expansion coefficient near zero ("Zerodur" from Schott). But the majority of materials suffer thermal expansion.
What happen to air particles as they heat up and cool down?
Depends on the container of the "air particles" and what you mean by "what happens." If it is inside a container that can not expand, then the pressure increases. If it is inside a container that can expand (or is just atmospheric air) then the volume increases. (Pressure * Volume = n * R * change in temperature) On the atomic level, the atoms or molecules (depending on the gas) begin to move more quickly as their kinetic energy increases.
Why does liquid inside a thermometer rise as the temperature s increase?
Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.
Do The resistance of a material generally increases as its temperature increases?
The answer to this depends on the material from which the resistance is made. For most materials resistance increases with increasing temperature. This is referred to as having a "positive temperature coefficient". Some materials have a negative temperature coefficient; these do have uses in electronics.
Why do telephone wires in warm weather slack?
All materials expand with temperature increases. This expansion in the metals and plastics of phone lines would cause them to lengthen, and thus go slack.
What is the characteristic of matter that causes it to expand when the temperature increases and contract when the temperature decreases?
The characteristic of matter that causes it to expand when the temperature increases and contract when the temperature decreases is known as thermal expansion. This is because as the temperature rises, the particles within the material gain kinetic energy and move more, causing the material to expand. Conversely, when the temperature decreases, the particles lose kinetic energy and move less, leading to contraction.
Does a thermometer's mercurry expand contract on condenses?
it expands and contracts when the temperature drops, the mercury contracts...when the temperature increases, the mercury expands
What happens to the volume of a material when it is heated?
It depends on the material. Most materials would expand and the volume would increases.
Do gases expand in heat?
Yes. If the temperature increases, the gas expands (assuming the pressure remains constant).
What happens to the volume of Balloon left on a sunny windowsill?
It would increase. The balloon would expand because when temperature increases, volume increases as well.
What two factors influence density?
Temperature and Pressure! As temperature increases, density will tend to decrease. Conversely, as pressure increases, density will increase. I say "tend to" because water will actually expand as temperature reduces through its freezing point! Cheers, Robin
Why would an engineer need to know the effect of temperature on a solid?
Things expand when heated, and different materials expand differently. An engineer needs to calculate HOW MUCH things expand, and factor this in when designing anything.
Why does alcohol in a thermometer rise?
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
What type of relationship does the graph for charles's law show?
It shows that the volume of a gas increases at the same rate that the temperature increases.
