The Fahrenheit thermometer scale is
No more accurate than the Celsius scale
On the Celsius temperature scale
The numbers relate to the boiling and freezing of water
Internal energy refers to the
Total potential and kinetic energy of the molecules
External energy refers to the
Total potential energy and kinetic energy of an object that you can measure directly
Heat is the
Total internal energy of an object
The specific heat of copper is .093 cal/C°, and the specific heat of aluminum is 0.22 cal/gC°. The same amount of energy applied to equal masses, say, 50.0 g of copper and aluminum, will result in
A higher temperature for copper
The specific heat of water is 1.00 cal/C°, and the specific heat of ice is 0.500 cal/gC°. The same amount of energy applied to equal masses, say, 50.0 g of water and ice, will result in (assume the ice does not melt)
A greater temperature increase for the ice
The transfer of heat that takes place by the movement of groups of molecules with higher kinetic energy is
Convection
The transfer of heat that takes place by energy moving through space is
radiation
The transfer of heat that takes place directly from molecule to molecule is
conduction
The evaporation of water cools the surrounding, and the condensation of this vaporwarms the surroundingThe heat involved in the change of phase from solid ice to liquid water is calledlatent heat of fusionThe energy supplied to a system in the form of heat, minus the work done by the system, is equal to the change in internal energy. This statement describes thefirst law of thermodynamicsIf you want to move heat from a region of cooler temperature to a region of warmer temperature, you must supply energy. This is described by thesecond law of thermodynamics
