Which statement is true in relation to the kinetic energie of a molecule? A It is lowest at low temperatures but increases at higher temperatures C It remains the same at all temperatures D It is lowest at high temperatures?
Given that the kinetic energie, KE, is equal to m *v2/ 2, and that the speed is greater at lower temperatures than at higher temperatures, it is easy to conclude that the kinetic energetic of a molecule at low temperatures is the lowest, i.e. the option A.
What does kinetic energy do to molecules?
Kinetic Molecular Theory says that gas particles are constantly in motion and exhibit perfectly elastic collidings. Kinetic Molecular Theory is able to explain both Charles’s and Boyle’s Laws. Absolute temperature is the only thing that directly affects the average kinetic energy for a collection gas particles.
How do we measure the kinetic energy of molecules?
It is difficult to determine the speed of a single gas molecule. Temperature can instead be used to measure the average kinetic energy for all molecules in the gas. Temperature rises as the gas molecules move faster and gain more energy.
What is the relationship between kinetic energy and state of matter?
The kinetic molecular theory states that matter is composed of particles that move constantly. Although all particles possess energy, the temperature at which the matter sample is kept can affect the amount of energy. This determines whether the substance is in a solid, liquid, and gaseous state.
Which of the following has minimum kinetic energy?
particles below zero degrees celsius because ice, which is a solid, makes it difficult for particles to move due to strong intermolecular attraction.
Do all gases have same kinetic energy?
The average kinetic energie of gas particles is proportional the absolute temperature of the gas. All gases at the same temperature have an equal average kinetic energetic.
What is kinetic theory of ideal gases?
Kinetic theory of ideal gases. Kinetic Theory for Ideal Gases. THEORY. THEORY. An ideal gas is one in which the atoms don’t exert any forces on one another, but they collide with the walls of a container (in elastic collisions).
What is the correct definition of energy?
What is energy? The ability to perform work. What type of energy is stored as chemical compounds or released through chemical reactions? chemical energy. What type of energy is the energy for motion?
Which type of energy is water held by a dam an example of?
