What is a measure of average kinetic energy of a group of molecules?
The temperature of a sample of nitrogen gas is a measure of the molecules' average # activation energy # potential energy # kinetic energy # ionization energy Answer 3 Reason Temperature measures average kinetic energy.
Compared to the average kinetic energy of 1 mole of water at 0 degree Celsius the average of kinetic energy of 1 more of water is 298 K is?
greater, but the number of molecules is the same
When a gas is heated does all of the absorbed energy convert to kinetic energy If not please tell what it is converted to part kinetic and part potential energy or just potential energy?
The gas will have thermal energy given by its specific heat capacity (at constant pressure or volume depending on the situation) times the rise in temperature. This thermal energy is possessed because of the increased kinetic energy of its molecules, due to the rise in temperature.
Temperature is proportional to the average kinetic energy of particles in an object thus an increase in temperature results in a?
Thermodynamic temperature (absolute temperature) is proportional to the averagekinetic energy of particles in "gases". An increase in temperature will increase theaverage kinetic energy of the particles of the gas and at the same time the particle'skinetic energy distribution gets broader.If pressure of the gas is kept constant, the gas expands (increases its volume).If the volume of the gas is kept constant, the gas pressure increases.
Does gas molecules with more kinetic energy lower pressure?
more KE==> higher temp and for the same volume ==> higher pressure.
What happens to the pressure as a fluid moves faster?
As the average kinetic energy of the molecules in a fluid increases, the pressure will increase. This can be found by considering the ideal gas equation: PV=nRT where P is pressure, V is volume, n is the number of molecules, R is constant, and T is the temperature. As temperature is a measure of the average kinetic energy, and you are increasing the kinetic energy of the particles here, to hold all else constant, the pressure must also rise within the system.
Do molecules have the lowest average kinetic energy in a plasma?
No. Molecules have the lowest average kinetic energy in a solid. Plasma is the highest average kinetic energy.
What happens to kinetic energy of gas particles as temperature decreases at a constant pressure?
kinetic energy increases with the increase in temperature is a postulate in kinetic molecular theory of matter.if the pressure is kept constant when temperature decreases the kinetic energy of the molecules decreases resulting in decrease in the volume of the gas. Charle's Law state's that For a given mass of dry gas at constant pressure ,volume is directionally proportional to temperature ie V~T
What is the average kinetic energy of all the molecules in an object is?
The average kinetic energy of all the molecules in an object is the temperature.
What is the measurement of the average kinetic energy of the molecules of a substance?
temperature is the average kinetic energy of a particle
How are temperature and kinetic energy related?
Matter is made up of particles (atoms and molecules); temperature is closely related to the average kinetic energy per particle. More precisely, the average kinetic energy per particle per degree of freedom.
The measure of the average kinetic energy of a group of molecules?
Temperature is the average kinetic energy
All the molecules of a substance possess the average kinetic energy value?
This is false not all the molecules of a substance possess the average kinetic energy value. Temperature increases as the average kinetic energy of a gas increases.
Heating a constant volume make its pressure higher why?
When you heat atoms or molecules, you cause them to move more quickly; that is what heat is, the average kinetic energy of the constituent particles. And when they move more quickly they bounce off the walls of their container with more force, thus exerting more pressure.
What happens to the average kinetic energy of the water molecules in your body when you have a fever?
The average kinetic energy of water molecules goes up. Fevers cause the internal temperature to rise which increases kinetic energies.
Why do all gasses exert pressure in terms of KMT?
Pressure is the effect of collisions with molecules. KMT -- molecules have kinetic energy due to their temperature which imparts more velocity, hence kinetic energy, to the molecules. All gases have KE due to temperature. IF absolute zero was ever achieved there would be no kinetic energy in the molecules, no molecular motion, no collisions, no pressure.
What is the average kinetic energy of all the molecules in an object called?
The average kinetic energy of the particles in a substance is its temperature.
