* Higher temperature = Faster particle motion: As the temperature of an object increases, the particles within that object move faster. They vibrate, rotate, and translate (move from one place to another) with greater energy.
* Lower temperature = Slower particle motion: As the temperature of an object decreases, the particles within that object move slower. They vibrate, rotate, and translate with less energy.
Here's a more detailed breakdown:
* Kinetic Energy: The energy of motion is called kinetic energy. The faster particles move, the more kinetic energy they possess.
* Temperature and Kinetic Energy: Temperature is a measure of the average kinetic energy of the particles in a substance.
* Heat Transfer: When heat is added to an object, the particles absorb that energy and move faster, increasing the object's temperature. Conversely, when heat is removed, the particles slow down, decreasing the object's temperature.
Examples:
* Boiling Water: When water is heated, the water molecules absorb energy and move faster. Eventually, they move so fast that they break free from the liquid state and become steam.
* Freezing Water: When water is cooled, the molecules slow down. Eventually, they slow down enough to form a rigid structure, becoming ice.
Important Note: This relationship holds true for all states of matter (solid, liquid, and gas), but the specific types of motion (vibration, rotation, and translation) are different in each state.
