Why does lowering the pressure make there less collisions?
Pressure is due to particles colliding with the walls of the container in which the system is encompassed. Therefore, for a lower pressure (with the same number of particles), the particles would have to collide less frequently with the container walls.
Which term is defined as a measure of the average kinetic energy of particles in a sample?
temperature
The pressure of gas decreases with increasing temperature?
If the temperature decreases, the volume is also going to decrease, and if the pressure decreases, the volume is going to increase. So they balance each other out, if they are decreased at the same rate.
If the pressure and number of particles are constant?
Then the specific volume varies directly with temperature.
How are pressure and the number of the particle related?
PV = NkT P: pressure V: volume N: number of particles in gas k: Boltzmann's constant T: absolute temperature More particles in a constant volume, constant temperature space means more pressure.
What the increasing temperature doas to the particles and how this affects the number of collisions?
Increase in temperature cause the particles to move faster, which in turn would increase the number of collisions. If the volume did not change and the temperature increased, the pressure would also increase.
When the temperature of a gas gets higher what does its pressure do?
Increase. As the temperature increases, the particles hit the walls of the container more often and with more force. This causes the pressure to increase, since the definition of pressure is the number and force of collisions the particles have with the walls of its container.
Simultaneous collisions of billions of gas particles with an object result in?
gas pressure is the result of simultaneous collisions of billions of gas particles with an object
Gas pressure is caused by collisions between?
particles. are you dumb?
What are two conditions that determine the mass of solute that will dissolve in a given mass of solvent?
The temperature: Increasing temperature makes the particles move faster. Heat energy is transferred by the movement of the particles. Because the solvent particles are moving faster, they bump into the solute.Stirring: Moves all the particles around do the solvent particles bump into the solute particles.
What causes pressure?
The weight of the air The distance between particles of a gas determines the pressure. The distance can be decreased and the pressure therefore increased by either increasing the amount of particles of gas in the container, or by reducing the size of the container.
If you wanted to predict how temperature will effect the volume of a gas what factors must be held constant?
If temperature increases, then pressure increases. Temperature measures the average speed of particles, so if the temperature is high, then the particles are moving quickly and are colliding with other particles more forcefully. Pressure is defined as the force and number of collisions the particles have with the wall of its container. So if the high temperature causes the particles to move quickly, they are going to collide more often with the container, increasing the pressure. This remains true as long as the number of moles (n) remains constant.
How is the pressure affected by the collision of gas particles?
The more the collisons the higher the pressure, the lesser amount of collisons the lower the pressure.
How does depth and temperature affect pressure?
temperature is the average kinetic energy of the atoms of a gas. so with increased temperature the speed of the atoms of gas would increase. and since pressure is the collisions of said atoms on the side of a container; increased speed means more collisions of the particles and the side of the container increasing the pressure, and the same aplies for lowered temperature lower temp lower speed and less collions and less pressure.
The pressure of a gas decreased with increasing temperature?
False
What happens to the pressure of a system when the volume is decreased if the temperature and number of gas particles are held constant according to Boyles Law?
When pressure double, the volume halves. However this is only true if the number of molecules and the temperature are both in a constant state.
What is the pressure caused by the collisions of particles in a water vapor with the walls of a container?
Contact between the particles of a gas and walls of the container cause pressure in a closed container of gas.
