welcome to heat
- Key Terms physic class
Absolute zero: The temperature at which a substance has no kinetic energy per particle(thermal) to give up.
bimetallic strip: Two strips of different metals, such as one of brass and one of iron, welded or riveted together into one strip. Because the two substance expand at different rates, when heated or cooled the strip bends.
calorie: A unit of heat is the heat required to raise the temperature of one gram of water one Celsius degree.
Celsius scale: A temperature scale with 0 as the melt-freeze temperature for water and 100 as the boil-condense temperature of water at standard pressure.
Fahrenheit scale: The temperature scale in common use in the united state. The number 32 is assigned to the freezing point of water, and the number 212 to the boiling point of water at standard atmospheric pressure.
heat: Energy transfer via random molecular motions, resulting in gain or loss of internal energy to mechanical work.
internal energy: The total energy stored in the atoms and molecules within a substance.
Kelvin scale: The total energy stored in the atoms and molecules within a substance.
Kilocalorie: A unit of heat. one kilo-calorie equals 1000 calories, or the amount of water by 1degree.
specific heat capacity: The quantity of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. often simply called "specific heat", or "heat capacity".
temperature:Temperature is related to the random motions of the molecules in a substance. In the simplest case of an ideals gas, temperature is proportional to the average kinetic energy of molecular translational motion.
thermal contact: The state of two or more objects or substance in contact such that it is possible for heat to flow from one object or substance to another.
thermal equilibrium:The state of two or more objects or substance in thermal contact when they have reached a common temperature.
thermostat:A type of valve or switch that responds to changes in temperature and that use to control the temperature of something.
