Temperature & heat Physics 100 Chapt 9
Temperature scales Fahrenheit 212 F room temp 27 C 300 K 80 F 32 F -459 F
Thermal atomic motion Air solid Heat energy= KE and PE associated with the random thermal motion of atoms
Summary • Heat is energy associated with random motion of atoms & molecules in material • Temperature tells you the average “thermal” energy (including KE & PE) of atoms & molecules • At absolute zero (T=0K, or -273C, or -459F)motion of atoms & molecules in material ceases.
