Measure of the kinetic energy of the atoms of an object?
Temperature
When heat flows into an object and its temperature rises the change in temperature is what?
Caused by vibrations of the atoms or molecules that make up the object.
How are the atoms in an object affected when the temperature of the object increases?
Well, when the thermal energy of a substance increases, the temperature increases. When the temperature reaches the boiling or melting point, the state of the matter changes from one to another.
Why an object can never reach a temperature of absolute zero?
At absolute zero, the object would lose all energy, down to the atomic level. Atoms without energy are not atoms. Objects, mass, cannot exist without atoms.
Explain the difference between an object's external temperature and its thermal energy?
The thermal energy of an object consists of the total kinetic energy of all its atoms and molecules. The temperature of the object is a measured average intensity of its thermal energy.
Why does an ice cube melt when compressed even though the temperature remains the same?
When force is applied to an object and the object is unable to compress as a whole, the energy is then transfered to the atoms causing them to vibrate. Vibration of atoms is directly connected to temperature as temperature is really the measure of movement of the atoms. The more the atoms vibrate the higher the temperature. This increase in temperature causes the ice to melt.
What is an object's temperature related to?
kinetic energy of its atoms
Measure of the kinetic energy of the atoms of an object?
Temperature
When the temperature of a substance the motion of the atoms that make up that substance .?
Increase, increase
What is Heat flows into an object an its temperature rises an the change in temperature?
Caused by vibrations of the atoms or molecules that make up the object.

An increase in the average kinetic energy of a sample of copper atoms occurs with an increase in what?
Temperature
When the temperature of a substance decreases increases what happens?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
If you raise the temperature what happens to an object's density?
The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)

How is the thermal expansion works?
as the temperature increases the atoms in a metal gain energy so the KE of the atoms increase this increase their movement for this it requires more space so it expans to increase the gap between the atoms or molecules
Describe the change in kinetic energy when the temperature of an object increases?
The more an objects kinetic energy increases the more it's temperature increases. An object that is traveling at 30 miles per hour will have a higher temperature than an object traveling at 10 miles per hour. This is in part due to friction. Mostly however, it is due to the fact that kinetic energy excites atoms in the object raising the objects temperature. You could put it like this: temperature = energy + atoms. Hope this helps.
