Which are the first particles to evaporate from a liquid?
The particles that evaporate from a liquid are on the surface of the liquid.
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.
Can water be evaporate or condense if its continuous or not made of particles?
It is actually impossible for water to condense or evaporate if it is continuous and not made of particles because these what make water to be condensed and evaporated in the first place.
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.
What are the main factys of conduction?
Thermal conduction is the transfer of heat energy through particles in contact with one another. Because heat energy is essentially kinetic energy, the particle with more kinetic energy collides with the particle with less kinetic energy, speeding it up and therefore causing it to absorb some of the heat energy from the first particle.
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 you turn on a fan electrical energy changes into?
The electrical energy is converted to kinetic energy and heat. The kinetic energy is first seen in the blades of the fan as they rotate. This kinetic energy is converted to air movement, another form of kinetic energy. The electrical energy isn't fully converted to kinetic energy but turns into heat. This is generated by the magnetic fields of the motor and friction. Both of these are considered to be losses of energy but in fact they are simply a conversion to a form of energy that is not of use.
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.
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
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.
