What else can I help you with?
What is all matter is made of atoms and molecules that are in constant?
The total mass remain constant after a chemical reaction.
What is Avogadro number the constant for?
Avogadro's constant is the number of atoms or molecules of a substance in 1 mole of that substance.
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.
What is held constant in water?
The proportion of hydrogen and oxygen atoms in its molecules.
How can you use a bottle of perfume in a room to show that the molecules in a gas are in constant motion?
You can demonstrate that gas molecules are in constant motion by spraying a bottle of perfume in a room. As the perfume molecules disperse, they spread throughout the air, illustrating their movement as they collide and scatter in all directions. Over time, the scent becomes detectable even at a distance, showcasing how gas molecules can travel and mix with surrounding air molecules due to their kinetic energy. This observable diffusion highlights the dynamic nature of gas molecules in constant motion.
What is Avogrado's constant?
*Avogadro's Constant is 6 x 10^23, representing the number of particles (ie. atoms/ions/molecules) in one mole of any substance :)
What does the constant collision of gas molecules against the inside walls of a container produce A Temperature Bdensity C Pressure Ddiffusion?
C. Pressure. The constant collision of gas molecules against the inside walls of a container produces pressure. This pressure is a result of the force exerted by the molecules as they collide with the walls of the container.
Are molecules free moving?
Yes, molecules are in constant random motion due to their thermal energy. This movement allows them to collide, react, and interact with other molecules in their environment.
Is gas molecules are in constant motion but molecules in liquid and soilds are not.is it true?
Not true. gas molecules move more rapidly, but all molecules have SOME movement at any temperature above absolute zero.
What is the physical significance of vander walls constants a and b?
Vander Waals constant 'a' represents the attraction between gas molecules, while constant 'b' represents the volume occupied by the gas molecules. 'a' is related to the cohesive forces between molecules, while 'b' is related to the excluded volume due to the size of the molecules. These constants help account for deviations from ideal gas behavior in real gases.
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
How many gas molecules are there in 1 mole of NO2?
The amount of 1 mole: 6.022 * 1023 (Avogadro's constant)
