What is the average speed of gas molecules in a given sample at a specific temperature and pressure?
The average speed of gas molecules in a sample at a certain temperature and pressure is determined by the kinetic theory of gases. This speed is directly proportional to the square root of the temperature and inversely proportional to the square root of the molecular weight of the gas.

What is the average distance between oxygen molecules at Standard Temperature and Pressure (STP)?
The average distance between oxygen molecules at Standard Temperature and Pressure (STP) is approximately 3.3 nanometers.
What is the velocity of hydrogen?
The velocity of hydrogen can vary depending on the specific conditions, such as temperature and pressure. In a broad sense, hydrogen molecules at room temperature have an average velocity of about 1.8 km/s.
When the temperature of a gas is lowered what happens to the pressure?
When the temperature of a gas is lowered, the average kinetic energy of the gas molecules decreases, leading to slower-moving molecules. This results in fewer collisions with the walls of the container and therefore a decrease in pressure.
What is a measure of the average of motion of molecular?
The measure of the average motion of molecules is temperature. Temperature is a reflection of the average kinetic energy of the molecules in a substance.
The measure of the average kinetic energy of a group of molecules?
The measure of the average kinetic energy of a group of molecules is expressed as temperature. As temperature increases, molecules move faster and their kinetic energy increases. This average kinetic energy is directly related to the temperature of the system.

Average speed of air molecules?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
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.
What is the average speed of oxygen molecules in air is about?
The average speed of oxygen molecules in air at room temperature (around 20°C) is approximately 460 meters per second. This speed can vary depending on factors such as temperature and pressure.
The average vibration of molecules in an object is measured by?
The average vibration of molecules in an object is typically measured using temperature. Temperature is a measure of the average kinetic energy of the molecules in the object, which is directly related to their vibrational motion. By measuring the temperature of an object, we can infer the average vibrational energy of its molecules.
When the temperature of a gas is lowered what happens to the pressure?
When the temperature of a gas is lowered, the average kinetic energy of the gas molecules decreases, leading to slower-moving molecules. This results in fewer collisions with the walls of the container and therefore a decrease in pressure.
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 is a measure of the average of motion of molecular?
The measure of the average motion of molecules is temperature. Temperature is a reflection of the average kinetic energy of the molecules in a substance.
How many molecules in a one inch square column of air?
It is not possible to provide an exact number without knowing more specific information such as the pressure, temperature, and composition of the air. However, on average, there are approximately 2.5 x 10^19 molecules in a cubic centimeter of air at sea level.
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.
Mean free path of water molecule?
The mean free path of a water molecule is the average distance it can travel between collisions with other molecules. In the case of water at room temperature and pressure, the mean free path is typically on the order of micrometers to millimeters. This can vary depending on the specific conditions of temperature and pressure.
