What does the experiment suggest about the average speed of hydrogen molecules compared with the average speed of molecules in the air?
The experiment suggests that the average speed of hydrogen molecules is higher than the average speed of molecules in the air. This is because hydrogen molecules are lighter and have a higher root mean square speed due to their lower mass.
What measures the average speed of air molecules?
The temperature of a gas is related to the average kinetic energy of its molecules, which is directly proportional to their speed. Therefore, temperature indirectly measures the average speed of air molecules.
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.
How does the average speed of air molecules relate to the temperature?
The average speed of air molecules increases with temperature. This is because higher temperatures provide more thermal energy to the molecules, causing them to move faster on average. Conversely, lower temperatures result in slower average speeds of air molecules.
How does the average speed of the water molecules change as they are heated?
As water molecules are heated, their average speed increases. This increase in speed is due to the increase in kinetic energy of the molecules, causing them to move faster. This relationship is described by the kinetic theory of gases.
A measure of the speed of molecules is the?
A measure of the speed of molecules is the temperature of the substance they are in. Temperature is related to the average kinetic energy of the molecules, and the higher the temperature, the faster the molecules will be moving.
Average speed of air molecules?
A thermometer. Temperture is the measure of the kinetic energy, Aka speed, of molecules.
How does the speed of molecules of gas change when heated?
When gas molecules are heated, their kinetic energy increases, causing them to move faster. This increase in speed leads to higher average velocity and greater collisions with other molecules, resulting in an overall increase in the gas pressure and volume.
In which state will atoms and molecules have the lowest average speed?
Solids.
How can you speed up the chemical reaction between lemon juice and marble?
You can speed up the chemical reaction between lemon juice (acid) and marble (calcium carbonate) by increasing the temperature, crushing the marble to increase surface area, or using a catalyst like citric acid to enhance the reaction rate.
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.
Is there a way to add fresh lemon juice to cream sauces so that the sauce doesn't curdle?
To make lemon cream in a mixing bowl you mix together cream with a little sugar and then whip it at full speed until peaks form then add the lemon juice and rind and fold it into the mixture gently with a desert spoon that you have chilled in the fridge
