How does the volume of an ideal gas at constant temperature and pressure change as the number of molecules increases?
The volume of an ideal gas will increase as the number of molecules increases at constant temperature and pressure. This relationship is described by Avogadro's law, which states that the volume of a gas is directly proportional to the number of molecules present, assuming constant temperature and pressure.
What is a statement that the volume of a fixed amount of gas varies directly with the temperature of the gas?
The volume of a fixed amount of gas increases as the temperature of the gas increases, assuming pressure is held constant. This relationship is described by Charles's Law, a gas law that states that volume is directly proportional to temperature.
How does temperature effect the pressure of a gas?
If the volume of the container is not fixed, increasing the temperature will cause a gas to expand (increase the volume), and contract when cooled (decreasing the volume). This would be the case for a gas inside a piston, or inside a rubber balloon. If the volume is fixed, then increasing the temperature will increase the pressure, and decreasing the temperature will decrease the pressure. This would be the case for a gas in a closed solid container, like a canister or sealed metal box. Increasing pressure will cause the gas to contract (reducing the volume), and decreasing the pressure will cause the gas to expand (increasing the volume). Again, this is if the volume is not fixed. If the volume is fixed, then increasing the pressure will increase the temperature, and decreasing the pressure will decrease the temperature. These concepts are all determined by something called the Ideal Gas Law. To find out more about how this works, see the Related Questions links below this answer. Gases can also be changed to a liquid or solid if the temperature is too low or the pressure is too high. As an example steam changes to a liquid when it touches a cold object, and nitrogen gas can be converted to liquid nitrogen by compressing it to very high pressures.
What law does this describe law states that for a fixed amount of gas at a constant pressure the volume of a gas changes and the temperature of the gas changes too?
This describes Charles's Law, which states that the volume of a gas is directly proportional to its temperature when pressure is constant. In other words, as the temperature of a gas increases, its volume also increases, and vice versa.
How does Charles' law relate to density?
Charles' law is also known as the law of volumes. It states that the volume of a gas will expand when heated. This means that as gas is heated, its density lowers, because the same number of molecules now occupy a greater space.
What As a temperature of a fixed volume of a gas increases the pressure will?
Pressure will be decreased
If a fixed sample of gas increases in temperature it must also do what?
If a fixed volume of gas increases in temperature, it must increase in volume. If the gas is in a closed system, the pressure inside that system increases instead. When the gas increases in volume, it also decreases in pressure, often rising above colder, more dense gas if possible.
How does the volume of an ideal gas at constant temperature and pressure change as the number of molecules increases?
The volume of an ideal gas will increase as the number of molecules increases at constant temperature and pressure. This relationship is described by Avogadro's law, which states that the volume of a gas is directly proportional to the number of molecules present, assuming constant temperature and pressure.
What temperature of a fixed volume of a gas increases the pressure will?
According to Gay-Lussac's law, the pressure of a fixed volume of gas is directly proportional to its temperature in Kelvin. As the temperature increases, the kinetic energy of the gas molecules rises, causing them to collide with the walls of the container more forcefully and frequently. This results in an increase in pressure. Therefore, to increase the pressure of a gas, its temperature must be raised.
If a fixed sample of a gas increases in temperature at a constant pressure its volume does what?
If a fixed sample of gas increases in temperature at constant pressure, its volume will also increase. This is because as the temperature increases, the particles in the gas gain more kinetic energy and move faster, causing them to collide with the container walls more frequently and with greater force, thus occupying a larger volume.
When a fixed sample of gas increases in volume what happens to the pressure and temperature?
The frequency of collisions is reduced
What is a statement that the volume of a fixed amount of gas varies directly with the temperature of the gas?
The volume of a fixed amount of gas increases as the temperature of the gas increases, assuming pressure is held constant. This relationship is described by Charles's Law, a gas law that states that volume is directly proportional to temperature.
What is the relation between temperature and pressure for an incompressible fluid in a fixed volume?
For an incompressible fluid in a fixed volume, the relationship between temperature and pressure is direct: as the temperature increases, the pressure also increases. This is because the volume remains constant, so an increase in temperature leads to an increase in kinetic energy of the fluid molecules, resulting in greater pressure exerted on the container walls.
What happens to an enclosed gas if the temperature is increased?
For an enclosed gas (contained in a fixed volume), the pressure increases as temperature increases.Another way to picture this is that at higher temperatures, the gas molecules colliding with the walls of the container are more energetic, so the force exerted (pressure) is greater.
How does temperature effect the pressure of a gas?
If the volume of the container is not fixed, increasing the temperature will cause a gas to expand (increase the volume), and contract when cooled (decreasing the volume). This would be the case for a gas inside a piston, or inside a rubber balloon.

When a fixed sample of gas increases in volume?
When a fixed sample of gas increases in volume, its pressure decreases because the gas particles have more space to move around, resulting in fewer collisions with the container walls. The temperature of the gas typically remains constant.
Do solids have no fixed volume or shape?
Solids have a fixed volume or shape at room temperature or pressure.
