How does the volume of the particles of a gas compared to the space between the particles of a gas at normal pressure?
How does the volume of a gas particle compare to the space between the particles of a gas at normal pressure? The volume of the gas particles is much smaller than the space between the particles.
Does iron heat up more rapidly than aluminum?
The sum of all the energy of the molecules of an object is called the temperature of that object. Iron heats up more rapidly than does aluminum because it has a greater specific heat. Liquid water at 0C has to give up energy in order to become ice at 0C.
What happens to particles when they are heated?
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly.
Which characteristic of a gas sample results from the collision of gas molecules with the walls of its container?
The temperature of the gas sample is directly related to the average velocity of the gas particles. A gas exerts pressure as a result of the collisions of the gas molecules with the walls of the container.
How does the volume of the particles in a gas compare to the volume of the gas?
how does the volume of the particles in a gas compare to the overall volume of the gas. the volume of the gas particles is small compared to the overall volume of the gas. the distance between particles in a gas is much greater than the distance between particles in a liquid or solid.
How does the volume of one gas particle compare to the volume of the container?
The size of a gas particle is negligible as compares to the volume of the container in which the gas is placed. Gases are mostly empty space, and this is evident because gases can be easily compressed. It is easy to reduce the volume of a gas as compared to reducing the volume of a solid.
Why does Aluminium expand more than iron?
The coefficient for aluminum is 2.4, twice that of iron or steel. This means that an equal temperature change will produce twice as much change in the length of a bar of aluminum as for a bar of iron.
What happens to the molecules of gas when heated?
Molecules within gases are further apart and weakly attracted to each other. Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
How are the molecules of gas liquid and solid arranged?
Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
What happens when two gas molecules collide?
Collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved. Collisions are not “sticky”. The average kinetic energy of the gas molecules is directly proportional to the absolute temperature.
Why are collisions between gas molecules elastic?
All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved. The volume actually occupied by the molecules of a gas is negligibly small; the vast majority of the volume of the gas is empty space through which the gas molecules are moving.
