What else can I help you with?
A gas sample is held at constant temperature. What happens to the pressure of the sample if the volume is doubled and the number of molecules is doubled?
If the volume is doubled and the number of molecules is doubled while the temperature is held constant, the pressure of the gas sample will remain the same. This is because both the volume and the number of molecules increased by the same factor, resulting in no net change in pressure according to the ideal gas law.
The average speed of the molecules of a gas is proportional to the?
The average speed of gas molecules is proportional to the square root of the temperature of the gas. As the temperature increases, the average speed of the molecules also increases. This is described by the Maxwell-Boltzmann distribution of speeds.
What happen to the rate of dissolution as the temperature is increased in a gas solution?
The rate decreases.
What happens to acetone molecules when you add heat to a breaker of liquid acetone?
When heat is added to a beaker of liquid acetone, the acetone molecules gain energy and begin to evaporate into the air as a gas. The increased temperature causes the molecules to move faster and escape the liquid phase.
Why does the solubility of a gas generally decrease with an increase in temperature?
As the temperature of the water increases, its vapour pressure increases, meaning there is more water molecules leaving the surface than before. Gases have weak intermolecular forces and therefore high vapour pressures and will therefore be readily evaporating already. The increased presence of water vapour above the water (i.e. increased humidity) reduces the amount of the gas able to condense back into the liquid, meaning less gas is dissolved.
What happens when the temperature of a gas increased?
If you increase the temperature of a gas, its particles (atoms or molecules) will speed up. If it is in a closed container, the pressure will also increase.
What happens to the pressure of the gas if the temperature of the gas is increased?
The pressure of a gas increases with an increase in temperature.
What happens to the pressure of gas if the temperature of the gas is increased?
The pressure of a gas increases with an increase in temperature.
What happens to a gas when the temperature of the gas is increased?
The volume increases Source:
What happens to the rate of dissolution as the temperature is increased in a gas solution?
As the temperature is increased in a gas solution, the rate of dissolution typically increases. This is because higher temperatures provide more energy for the gas molecules to break free from their bonds and dissolve into the solvent. Ultimately, increased temperature often leads to a faster and more complete dissolution of the gas into the solvent.
What will happen to the kinetic energy of gas molecules trapped in a rigid container if the temperature is increased?
increased
What happens when a gas reaches its lowest temperature?
The molecules of the gas will stop moving.
What happens when adiabatic expansion of gas molecules occurs?
The temperature of the gas decrease.
What happen to the speed of the molecule of a gas when temperature is increased and pressure is constant?
When the temperature of a gas is increased while keeping the pressure constant, the speed of the gas molecules also increases. This is because the increase in temperature leads to a greater average kinetic energy of the gas molecules, causing them to move faster.
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
What happens to the rates of dissolution as the temperature is increased in a gas solution?
The rate decreases.
A gas sample is held at constant temperature. What happens to the pressure of the sample if the volume is doubled and the number of molecules is doubled?
If the volume is doubled and the number of molecules is doubled while the temperature is held constant, the pressure of the gas sample will remain the same. This is because both the volume and the number of molecules increased by the same factor, resulting in no net change in pressure according to the ideal gas law.
