What two factors determine the kinetic energy of moving object?
velocity and mass
Why is there kinetic energy?
because there is kinetic energy.
Does mind have kinetic energy?
No, the mind does not possess kinetic energy. Kinetic energy is energy that is created by a force or motion.
How do thermal energy and intermolecular forces behave with each other?
When there is more thermal energy, then there are less intermolecular forces.
How does an airplane flying have kinetic energy?
It has kinetic energy because it is moving. Just because it is in the air doesn't mean that it can't have kinetic energy.
What is the phase with the highest kinetic energy and lowest intermolecular attractions?
the gas phase
What temperature will a solid melt?
The temperature at which intermolecular forces push the molecules apart
What happens when things get hotter?
when things get hotter the kinetic energy of their particles increase thus reducing intermolecular force and increasing intermolecular spaces
What factors determine an object's kinetic energy?
Look at the equation for kinetic energy. It clearly shows that the kinetic energy depends on the object's mass, and its speed.
Explain the factors that determine an object's kinetic energy?
There are two factors that determine and object's kinetic energy. The two main factors are mass and velocity.
Are intermolecular forces stronger in liquids or gases?
Intermolecular forces are stronger in liquids than in gases. A gas is the physical state characterized by the complete dominance of kinetic energy (disruptive forces) over potential energy (cohesive forces). Thus, gas particles move independently of one another. On the other hand, a liquid is the physical state characterized by potential energy (cohesive forces) and kinetic energy (disruptive forces) of about the same magnitude. So, the particles in the liquid have enough kinetic energy to move and slide past one another, but are still held together by any intermolecular forces. The particles in the liquid will break free of any intermolecular bonds once they obtain enough kinetic energy.
What causes particals to evaporate and leave the surface of a liquid?
Molecules at the surface of a liquid absorb kinetic energy (kinetic energy used to disrupt intermolecular forces) and evaporate. (vapor pressure is exerted)
How does radiation transfers heat energy?
Radiation and heat energy are manifestations of the same thing. Heat is a measure of kinetic energy. Radiation is the emanation of particles or energy that can interact with matter and, as such, change its kinetic energy and, thus, its heat.
What is the relationship between the strength of the intermolecular forces and boiling point?
Boiling can only occur when the kinetic energy of heat overcomes the intermolecular forces holding a liquid together, so the greater the intermolecular forces, the higher the boiling point.
What makes a liquid different from a solid of the same substance?
the arrangement of it's molecules...... which depend on kinetic energy and intermolecular force.
What are two factors that that determine objects kinetic energy?
Mass, speed.
What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
