What is the average kinetic energy of all the molecules in an object?

Average KE for molecules is defined by (3/2)RT: where R is the ideal gas constant (8.314 J K-1 mol-1 ) and T is the absolute temperature of the fluid (gas/liquid) in Kelvin. The reason for 3/2 is based on the x,y, and z planes that the gas molecules could be moving (vibrating, translating, rotating). For just a single plane it would be 1/2RT. The KE derived from the equation is the average KE for a mole of gas molecules and not the energy of every, or any of the molecules. A single gas molecules chosen at random may have any KE associated with it, but this equation gives the average of all molecules

What is the average kinetic energy of particles in an object can be measured by its?
By its Thermal Energy.
Why do particles have different amounts of kinetic energy?
Because they have different temperatures and when you measure an object's temperature, you measure the average kinetic energy of all the particles in the object.
What does a doctor use to measure the average kinetic energy of the molecules in your body?
Let us first define Kinetic Energy. Kinetic Energy is often referred to the energy a mass has due to its motion. However, when referring to the heat of an object, Kinetic Energy refers to how excited the particles are of the object. A measure of heat of the human body could be taken as temperature which has the SI units Fahrenheit, Celsius, or Kelvins. Therefore, the measure of the Kinetic Energy of the human body, as a standard: the human body has a temperature of 37 degrees Celsius.
Is it true that temperature is the measure of the average kinetic energy of the particles in an object?
For the "ideal gas" kinetic theory gets the following relation:Ek = 3/2 RTwhere Ek is the average molar kinetic (translation) energy, R the universal gas constant and T the thermodynamic temperature.Solids molecules or atoms don't have translation energy, changes in their internalenergy are given by changes namely in their vibrational energy components.
How is kinetic energy formed?
Kinetic energy is a form of energy that comes from motion. Therefore any moving object (that has a mass!) has kinetic energy. For kinetic energy to be produced, a force must act upon an object to give it an acceleration, to put it in motion. The simplest case is the conversion of potentiel energy to kinetic energy. When an object is far from its "normal" standing position (in this case the ground), it is said to have potential energy. When this object is attracted by the force of gravity, its potential energy is slowly converting into kinetic energy because the objet keeps on accelerating.
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 average kinetic energy of all the molecules in an object called?
The average kinetic energy of the particles in a substance is its temperature.
How does temperature increase or decrease?
Temperature is the average Kinetic energy of molecules in an object. A hot object has more kinetic energy and a cold object has less kinetic energy.
What is the average kinetic energy molecules in an object called?
It is Temperature
What is the total kinetic energy of the atoms and molecules in an object called?
Temperature is the measure of average kinetic energy of all the atoms and molecules in an object
The total kinetic and potential energy of the molecules of an object is know as?
The total kinetic and potential energy of the molecules of an object is thermal energy.
Is it true that the temperature of an object is a measure of the average kinetic energy of the molecules in the objects?
FALSE (APEX)
The average kinetic energy of the molecules in an object is what law of thermodynamics?
The root mean square of the velocity.
By increasing the temperature the temperature of water how are you changing the kinetic energy of the water molecules?
It is being increased, because temperature is the average kinetic energy of the object.
Measure of the average kinetic energy of the atoms in an object?
The temperature of an object is the most common measure of the average kinetic energy of the object.
How does temp effect the speed of molecules?
Temperature is the average kinetic energy of a set of molecules. Think about that: From physics, you know that the kinetic energy of an object is proportionate to its mass, and the square of its velocity. By adding heat to a system, you are adding energy. That energy is manifested as temperature.
Is the kinetic energy of a substance the kinetic energy of its particles?
No. The average kinetic energy of the individual particles in an object is basically related to the object's temperature.
