Temperature What can change the state of matter? Temperature Boiling Point = 212 degrees Freezing Point = 32 degrees Fahrenheit Boiling Point = 373 degrees Freezing Point = 273 degrees Kelvin/Absolute All molecular activity ceases at absolute zero. Fundamental Constant Absolute Zero -Directly Proportional  -Increase in pressure will cause an increase in temperature Temperature/Pressure relationship in a closed container -Directly Proportional -Pressure increases will raise boiling point -Pressure can chance the state, but not dominate factor Pressure/Boiling Point relationship in a closed container -Caused by movement of molecules Form of Energy Joules, Calories, & BTU’s Measurements of heat -Water is the standard  -Water has a value of one -Heat required to change one pound of a substance one degree 1 BTU ____ is required to change the temperature of one pound of water by one Fahrenheit. One BTU -Governs heat transfer  -States, heat travels from hot to cold - HEAT SEEKS COLD 2nd Law of Thermodynamics Conduction, through _____ objects, requires a medium SOILD Convection, through _____ objects, requires a medium FLUID Radiation, through _____ , doesn’t require a medium WAVES Controlling Heat Transfer: May be desired through - -Heat exchanger-Controlling air temperature • Radiation turned away by reflective material such as paint -Conduction reduced by a poor conductor such as stainless steel -Convection eliminated by a vacuum such as between two tanks How Heat Transfer is Eliminated; AuthorcarLORENZ0 ID255365 Card SetPHYSICS & TEMPERATURE BLVCK IV Description;slakjdf Updated2014-01-06T18:13:59Z Show Answers
