How fast is air molecules if temperature of the gas is 0 Celsius degrees?
The air molecules would go very slow because the air molecules are tight close together.
Does temperature have effect on efficiency of air bags?
Temperature should not have an effect on their efficiency. The chemical reaction is designed to quickly inflate the bag with nitrogen gas within 40 milliseconds of triggering.
What is the effect of temperature on the volume of a confined gas?
It will effect the Pressure [because the volume is constant]. Temperature is a measure of the kinetic energy of all the molecules of a particular substance. Low temperature means that the molecules are moving slowly. A high temperature means the molecules are moving very quickly. When particles are moving more quickly, they will hit against the walls of the container more frequently and with greater intensity, putting an expansionary pressure on the container, like a hot-air balloon. Conversely, slow moving particles hit against the walls of the container more infrequently and with less intensity, decreasing the overall pressure. Another way of saying this is that a hot gas will have greater volume and a cold gas will have less volume. OR, if you wish, hotter temperatures decrease the density of the gas while colder temperatures increase the density of the gas.
Why is there no gas pressure inside a vacuum?
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.
The boiling point is the temperature at which a substance changes from what?
Boiling point refers to the temperature at which a liquid boils and becomes a gas. This temperature varies according to;The substance in questionThe pressure of the surroundings
do bromine molecules move faster then air molecules?
The speed of gas molecules is primarily determined by their temperature, not their specific identity. At the same temperature, bromine molecules and air molecules would have similar average speeds.
How does temperature effect air pressure and air mass?
When gas molecules are heated, the molecules move more quickly, and the increased velocity causes more collisions. As a result, more force is exerted on each molecule and air pressure increases. Temperature affects air pressure at different altitudes due to a disparity in air density.
Why in the terms of gas motion in the air does the pressure rise?
Pressure increases if gas molecules slam into a surface either faster (higher temperature), hit harder (more mass), or more often (larger number of molecules). Pressure decreases if the gas molecules are generally moving parallel to the measuring surface, which is where the venturi effect and lift on wings can come from.
How many molecules are in one cubic meter of air?
That depends on the pressure and temperature of the air in the cubic meter. Any time you change the pressure or the temperature of a gas, you change the number of molecules in one cubic meter of it.
The average speed of the molecules of a gas is proportional to the?
Temperature.
What is the relationship between water vapor air molecules temperature?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
What is the relationship between temperature air molecules and water vapor?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
How fast is air molecules if temperature of the gas is 0 Celsius degrees?
The air molecules would go very slow because the air molecules are tight close together.
Is air made of molecules?
Yes. Air is a mixture of many gas molecules.
When a gas expands to a region of low pressure what happen to its temperature?
The temperature drops. When a real (non ideal) gas expands ( in such a way that it does not take in heat from the environment- so called adiabatic) for example when hot air rises into a low pressure region the gas will cools. Real gases when they expand freely cool, this is the basis of the refrigerator (Joule Thomson effect). The explanation is that the separation of gas molecules involves "work" done against intermolecular forces which leads to a reductio in the kinetic of the molecules, hence the observed temperature.
How does temperature affect the density of a gas?
With cooler temperatures, the gaseous molecules grow closer together and when the temperature is warmer, the gas molecules spread apart(out).
What is the relationship between the temperature and the pressure of gas?
If the temperature is low, then the molecules of the gas have less kinetic energy and thus it has low pressure. If the temperature is higher, then the molecules have more energy and thus the gas has higher pressure
