Is hot water denser than room temperature water?
Density: Mass/volume , so it is obious that density will changed with increase in temperature as volume is proportionaly changes with temperature so density will be decreases with increase in temperature. From this stand point we can say hot water has lower density then the water which is kept in room temperature. In 4'C water has higher density than other temperatures.
If the temperature of a gas in a movable piston is decreased what will happen to the density of the gas?
It will increase. Density is mass/volume. Mass remains constant since no matter is entering or escaping. Lowering the temperature decreases the volume. Same mass in a smaller space= increased density.
Does density of a substance generally decrease while the temperature increases?
No, the density of most substances typically decreases as the temperature increases. This is because the increase in temperature generally leads to an increase in the average kinetic energy of the substance's particles, causing them to move faster and occupy a larger volume. As a result, the density, which is defined as mass divided by volume, decreases. However, there are some exceptions, such as water, where the density increases between 0°C and 4°C due to changes in the structure of the water molecules.
What factor will increase the speed of a sound wave in the air?
Speed of sound would increase as the temperature of the air increases Speed of sound increases as humidity of air increases Speed of sound is affected by the density of the air. As density increases velocity of sound decreases
As water is cooled 4c to 0c its density?
the density of water is mostly high when its at 4 degrees celsius so the answer would be that the density of the water decreases from 4 degrees celsius to 0 degrees celcius
When temperature increases density increases or decreases?
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt
When temperature increases does density increase or decrease?
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt
How is it that the altitude decrease and the density of the air does what?
Altitude decreases, pressure increase, temperature decreases (some, but less effect than pressure), density goes up.
As temperature of the water decreases the density of water does what?
As temperature of liquid water decreases the density remains relatively stable until water changes phase change into solid (crystallization) ice at which point it decreases abruptly by about 10%. Continued cooling has little effect on the density of ice.

Temperature increase altitude increase?
No, it decreases.
Air density decreases with elevation increase. Is there an equation to make this calulation?
as you increase elevation (height above sea level0the density of the air decreases.
What happens to the density of air molecules as you increase in altitude?
the density decreases
What does an increase in temperature decreases?
presure
Does temperature increase with altitude?
No, it decreases.
What property will decrease if temperature increases?
Density will usually decrease in this case.
If the volume of an object increases what will the density do?
it will increase. the epuation for density is mass divided by volume.
