Which of the following is a postulate of the kinetic molecular theory?
As applied to gases, the kinetic molecular theory has the following postulates: Gases are composed of very tiny particles (molecules). The actual volume of these molecules is so small as to be negligible compared with the total volume of the gas sample. A gas sample is, then, mostly empty space.
Which postulate of the kinetic molecular theory best describes the event in the diagram?
Which postulate of the kinetic-molecular theory best describes the event in the diagram? All collisions between particles are perfectly elastic.
Which is a postulate of the kinetic molecular theory of gases quizlet?
What is a postulate of the kinetic molecular theory of gases? The particles that compose a gas are so small compared to the distances between them that the volume of the individual particles can be assumed to be negligible.
Which statement best describes a limitation of the kinetic molecular theory for a gas?
A limitation of the kinetic-molecular theory for a gas is the theory assumes that particles do not experience intermolecular forces. This cannot be completely true since interactions between particles is normal.
How does the kinetic molecular theory explain the pressure of gases?
The concept of pressure is explained in kinetic theory as a consequence of kinetic energy of gases. Due to the troublesome motion of the gas molecules, they will collide with each other, some of them shall collide with the container walls and then bounce back and this process continues.
What is an example of the kinetic molecular theory not holding true?
Which is an example of the kinetic-molecular theory not holding true for a gas? The attraction between particles causes a gas to condense at low temperatures.
What is the kinetic molecular theory of heat?
The Kinetic Molecular Theory of Heat states that molecules in a fluid increase their speed as temperature increases. Heat is the total internal kinetic energy of a system and temperature is the average kinetic energy of a system.
What is the relationship between the movement of molecules heat and temperature?
what is the relationship between molecular motion and temperature? The relationship between the two is that the higher the molecular motion is, the higher the temperature is.
What happens to molecules when they are cooled?
An increase in the motion of the atoms competes with the attraction between atoms and causes them to move a little further apart. Cooling a solid decreases the motion of the atoms. A decrease in the motion of the atoms allows the attractions between atoms to bring them a little close together.
