The measurement of hotness and coldness of a body is called temperature.
On the basis of molecular motion, the temperature is the average K.E of each molecules while the heat is total K.E of whole molecules of the substance. So, temperature depends on the K.E of molecules and heat depends on the total number of molecules that is mass of the body.
Suppose the Luke warm water in the beaker and boiling liquid in a spoon. The total KE of all the molecules of water in a beaker is greater than that in spoon because large number of molecules of water is in beaker than in spoon. Hence, heat is more in beaker and less in spoon. But, KE of water in a spoon is more than in Luke warm. Hence, temperature will be more in spoon than in beaker.
Any single atom or molecule has kinetic energy, but not a temperature. This is an important distinction. Populations of molecules have a temperature related to their average velocity but the concept of temperature is not relevant to individual molecules, they have kinetic energy but not a temperature.As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.
If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure. Temperature is directly proportional to the average translational kinetic energy of molecules in an ideal gas.
The kinetic molecular theory of matter explains how matter can change among the phases of solid, liquid, and gas.As an object falls under the influence of gravity, kinetic energy increasesy decreases / remains the same. ... An object travelling faster and faster while not changing height has a kinetic energy that increases / decreases / remains the same and a total mechanical energy that increases / decreases / remains the same.It turns out that an object's kinetic energy increases as the square of its speed. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy.
