What is the average kinetic energy of any substance at 0 K J?
0 Kelvin is the temperature where the is no kinetic energy, so the answer is 0.
When the kinetic energy of particles in a substance decreases will also decreases?
When the kinetic energy of particles in a substance decreases, what also decreases? The substance’s temperature.
At what temperature do the molecules of a substance theoretically lose kinetic energy?
Absolute Zero Eventually, one would expect the particles to stop moving completely. Absolute zero is the temperature at which the motion of particles theoretically ceases. Absolute zero has never been attained in the laboratory, but temperatures on the order of 1 × 10-10 K have been achieved.
When the kinetic energy of particles in a substance decreases What also decreases Brainly?
When the kinetic energy of particles in a substance decreases, it has nothing to do with the size of the particles and the specific heat capacity of the particles or substance. But it a clear indication that the substance temperature has also decreased.
What happens to the average kinetic energy of the molecules of a warm substance when the temperature of the substance is slightly decreased 5 points group of answer choices it increases it decreases it becomes zero it remains unchanged?
Average kinetic energy is defined as half of mass of gas times the square of root mean square velocity. Thus, we can conclude that the average kinetic energy of the molecules of a warm substance also decreases when the temperature of the substance is slightly decreased.
Which two factors affect the amount of thermal energy and object has Brainly?
Explanation: The amount of matter or mass and the temperature are the two factors that determine the thermal energy of an object. If a substance contains more mass, then it has more particles; hence, it has high thermal energy.
Which condition must exist in order for conduction to occur between two substances?
This process of exchange of heat is known as conduction. For example, a metal spoon placed in a hot coffee mug shows flow of heat from coffee to the spoon. Thus, we can conclude that a condition which must exist in order for conduction to occur between two substances is that the objects must be touching each other.
Which two conditions must exist in order for radiation to occur Brainly?
the presence of electromagnetic waves and direct contact of molecules. a temperature difference and the presence of electromagnetic waves.
Which condition must be met in order for an equation to be balanced?
1. An equation is balanced when the same number of each element is represented on the reactant and product sides.
What are the two conditions necessary?
Two conditions must be met in order for work to be done on an object. The first is that the object moves. The second is that a force must act on the object in the direction the objectmoves.
What are the two condition necessary for heat?
(i) The two objects should be in direct contact with each other. (ii) The temperature of the two objects should be different. Heat will flow from a hotter object to a cooler object.
What then is the condition necessary for heat transfer?
The factor or condition that is necessary for heat transfer to occur is that two object ‘must have different temperature’. Heat Transfer can occur in three ways: Conduction, Convection, and Radiation.
