If a sample of gas is heated what happens to the most probable speed of the gas?
When a sample of gas is heated, the average kinetic energy of the gas molecules increases, leading to an increase in their speeds. Consequently, the most probable speed, which is the speed at which the largest number of molecules are moving, also increases. This is due to the direct relationship between temperature and the average kinetic energy of the molecules in the gas. Therefore, as the temperature rises, the most probable speed of the gas molecules rises as well.
How does the mean speed of the water molecules changes as they are heated?

When the speed of a molecule decreases does the pressure of the gas decrease?
Yes, if the average speed of gas molecules decreases, the pressure of the gas will also decrease. This is because pressure is directly proportional to the average kinetic energy of the gas molecules, which is determined by their speed.
What is true about the speed of molecules in a sample of gas held at a constant temperature?
At a constant temperature, the average kinetic energy of the molecules in a gas sample remains constant. This means that while individual molecules may move at various speeds, the average speed is directly related to the temperature. As temperature increases, the average speed of the molecules also increases, and vice versa. However, at a constant temperature, the distribution of speeds can vary, but the average kinetic energy will stay the same.
Why does the speed of sound change if the temperature of the medium change?
The speed of sound is directly proportional to the temperature of the medium. This is because temperature affects the average speed of the molecules in the medium, which in turn affects how quickly sound waves can travel through it. As temperature increases, the speed of sound also increases due to the higher molecular activity.
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.
How does the speed of the molecules of a gas change when the ga is heated?
it moves faster
How does the speed of the molucules of a gas change when the gas is heated?
Molecules move faster when heated -- no matter what state they're in.
How does the speed of the molecules of a gas change when the gas is heatead?
When a gas is heated it's molecules begin to move faster and farther apart, juat as all other states of matter will when heated.
How does a liquid change into a gas when it is heated?
The molecules absorb more energy, more speed and can be released from the liquid.

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.
When the molecules in a body move with increased speed who will the body change?
When the molecules in a body move with increased speed, the body's temperature will increase. This increase in kinetic energy will cause the molecules to vibrate or move more rapidly, which translates to a higher temperature of the body.
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.
When a substace is heated how does the molecular motion change?
When a substance is heated, the molecules within it absorb energy and increase their kinetic energy, causing them to move more rapidly. This increased molecular motion leads to increased collisions between molecules and a higher overall temperature of the substance.
How does the speed of the molecules of a gas change when heated?
it moves faster
