Which are the first particles to evaporate from a liquid?
The particles with the highest kinetic energy are the first to evaporate from a liquid. These particles are usually found near the surface of the liquid where they can break free from intermolecular forces and escape into the air. This process is known as evaporation.
When you add energy to matter the particles move blank and the matter blank?
That depends a lot on how the particle was moving in the first place, and how the energy is added.
Which postulates of the kinetic molecular theory explain the observation that a sample of a gas with particles in rapid random motion does not cool down?
According to the kinetic molecular theory, gases consist of particles in constant random motion. Two postulates can explain why a sample of a gas does not cool down: First, the particles have a range of speeds, so while some may collide and transfer energy, others will collide and gain energy. Second, the average kinetic energy of the gas particles remains constant as long as the temperature is constant. Therefore, while collisions may occur and redistribute the energy, the overall average kinetic energy, and hence temperature, of the gas remains constant.
Describe a stone falling off the tabletop in terms of both kinetic energy and potential energy?
Sitting on the table the stone has potential energy, relative to the ground, of weight times height, mgh. It has zero kinetic energy so its total energy is E = 0 + mgh. When it begins falling it loses potential energy (as it loses height) and gains kinetic energy ( as it picks up speed) so the sum stays the same as initially E = KE + PE = mgh. Just before it hits the ground all of its potential energy is gone and has been transformed into kinetic energy. So the kinetic energy at the bottom (1/2)mv^2 will equal the potential energy at the top.
When potential energy turns into electrical energy which form of energy does potential first become?
Potential energy becomes static energy in the form of a difference of potential energy between two bodies, or clouds of charged particles. For instance the motion of any object against another object causes particles to become statically charged. That is potential and electrical. Once an electrical path is found between those fields the electrical force becomes similar to kinetic force and this is current.
A pole -vaulter first converts kinetic energy into?
Elastic Potential Energy
A roller coaster going down the first hill is an example of what type of energy?
It is kinetic energy because it is in motion.Jesus loves you! A car rolling down a hill is an example of which type of energy?kinetic...Potential energy
List all 5 states of matter in order of the highest kinetic energy to the lowest kinetic energy?
First, Gas- It has the most kinetic energy because it moves more freely. Second, liquid - It has okay kinetic energy. Then its Solid with the least kinetic energy.HOPE IT HELPED.
What is he relationship between temperature and kinetic energy?
Consider the example that you have a iron rod you start hearting one end by burner and after some time you will find that the whole iron rod is uniformly heated. First of all, when you give heat to anything the atoms constituting it will get energy and hence excited atoms oscillate (kinetic energy) and thus this process is transferred from atoms to atoms consecutively (atomes from one of the rod to the atoms at the other end) and thus heat is uniformly distributed on the whole iron rod.
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 the energy of nuclear fission released as heat?
Yes, as heat and radiation Nuclear fission actually releases first fission fragments and other particles with kinetic energy, which then turns to heat as the ejected fission fragments and part of the particles are slowed down within the mass of the solid fuel.
What energy occurs first potential or kinetic?
Energy is possessed by virtue of position, shape or motion or all the three properties. Generally potential energy is at first stored in a body which is released as kinetic energy when the body is in motion. But suppose if a body is thrown upwards vertically its kinetic energy gets converted into potential energy.
