How does the speed of the molecules change when ice changes to water?
When ice changes to water, the speed of the water molecules increases. In the solid state as ice, the molecules are held in a rigid structure and have minimal movement. As heat is added, the molecules gain energy, causing them to vibrate faster and break free from their rigid arrangement, resulting in the molecules moving more freely in the liquid state.
An indirect measurement of the speed of molecules is made with a?
An indirect measurement of the speed of molecules can be made using techniques such as Doppler spectroscopy or light scattering. These methods analyze the behavior of light as it interacts with the molecules to determine their speed indirectly. By studying the changes in the properties of the light, scientists can infer the motion and speed of the molecules.
In a bucket of water the instantaneous speed of molecules is closest to?
The instantaneous speed of water molecules in a bucket of water would vary due to the random motion and collisions between molecules. On average, the speed of water molecules at room temperature is around 500 m/s.
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 heat energy is added the speed of the molecules blank?
When heat energy is added, the speed of the molecules increases. This increase in speed leads to a higher kinetic energy and results in a rise in temperature of the substance.
Is there a chemical difference between the gauseos and liquid state of the same substance?
There is no chemical difference, the only difference is the speed in which the molecules of the substances move. Slower molecules can be solid or liquid and very high speed molecules can be gas.

When high speed molecules mix and collide with slower speed molecules the high speed molecules do what?
Slow down and the temperature drops.
What is the speed of motion?
A meaningless arrangement of words.
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.
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.
What are Four states of matter from slowest to fastest molecular speed?
Solid: molecules vibrate in place Liquid: molecules move freely but are still close together Gas: molecules spread out and move rapidly Plasma: molecules ionized and move at very high speeds

What effect does the speed of molecules haveon matter?
The speed of molecules directly affects the state and behavior of matter. As the speed of molecules increases, typically due to an increase in temperature, matter can transition from solid to liquid to gas, as seen in phase changes. Faster-moving molecules result in greater kinetic energy, leading to increased pressure and volume in gases, while slower-moving molecules indicate lower energy and greater stability in solids. Thus, molecular speed plays a crucial role in determining the physical properties and states of matter.
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.
How do you compare velocity and speed?
Velocity is a vectorial quantity, speed with a direction.
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.
