When the pressure of a gas increases at constant temperature its volume?
Temperature increases as pressure increases.
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.
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.
As the temperature increases materials with large coefficients of linear expansion increase a lot in size while materials with small coefficients of linear expansion increase a in size?
Large
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 does density decrease as temperature increases?
As temperature increases, the particles in a substance move faster and spread out more, causing the substance to expand and decrease in density.
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.
Does the circumference decrease as the temperature increases?
It is actually the opposite. When the circumference is greater, you are closer to the equator therefore you are getting more heat. When you circumference decreases, you are closer to the poles and have less heat.
How does temperature affect the resistance of conducting materials?
As temperature increases, the resistance of conducting materials also typically increases. This is because as temperature rises, the atoms in the material vibrate more, leading to more collisions with electrons, which in turn increases resistance. Conversely, as temperature decreases, resistance tends to decrease as well.
Why does liquid inside a thermometer rise as the temperature s increase?
As the temperature increases, the kinetic energy of the liquid molecules also increases, causing them to move more rapidly and spread out. This increase in motion leads to an expansion of the liquid, causing it to rise in the narrow tube of the thermometer.
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 molecules of water when the temperature of the water increases?
When the temperature of water increases, the molecules of water move faster and farther apart, causing the water to expand and eventually turn into steam.
Does an iron ring expands or contracts on heating?
An iron ring will expand when heated due to thermal expansion. As the temperature increases, the iron atoms vibrate more vigorously, causing the iron ring to expand. Conversely, when the iron ring cools down, it will contract due to thermal contraction.
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.
