PPT-Temperature, Heat, and Expansion

Temperature Most materials expand when heated Liquid thermometers based on mercury or alcohol expansion are common Temperature is related to the random motion of atoms and molecules in a substance . Heat Energy. Heat energy is due to the movement of atoms or molecules.. As atoms move faster they create more energy = causing Heat!. Thermal Energy. Depends upon the mass, temperature and phase of an object.. Physics of Everyday Life. Class 5: . Temperature, Heat. Temperature. Heat. Specific Heat Capacity. Thermal Expansion.

Someone left an article of clothing at the last exam, please see me if it is yours.. Most materials expand as the temperature increases.. A. temperature change of . Δ. T. , Heat, and Expansion. ”. (We will finish . Ch. 14 from last time on Friday). Temperature . How hot something feels is a measure of the kinetic energy of the constituent atoms/molecules – these are continually randomly jiggling.

Whereas . we may know how . the energy . transfer has occurred (because we can see if a weight has been raised or . lowered in . the surroundings, indicating transfer of energy by doing work, or if ice has . 1. = T. 2. . . The most common is Celsius temperature scale. T= 0. o. C is the melting point of ice, and T= 100. o. C is the boiling temperature of water at atmospheric pressure.. Many properties of matter depend on temperature. For most substances, volume increases upon heating (exception: water near freezing point, between 0.
