Basics$100Answer What is meant by thermal contact? Heat energies can be exchanged. Back to Jeopardy
Basics$200Answer What is meant by thermal equilibrium? Both objects are at the same temperature. Back to Jeopardy
Basics$300Answer Name the three temperature scales that are in common use. Give the boiling point and the freezing point of water, and absolute temperature in each scale. Back to Jeopardy
Basics$400Answer What does Temperature measure? The average kinetic energy of atoms and molecules in a substance. K.E. ATOM = ½mvAVE² = ½kBT where T in Kelvin Boltzmann’s Constant kB =1.38*10-23 J/K Back to Jeopardy
Constants$100Answer What is Avogadro’s number? NA = 6.02 *1023 units 1 mole contains Avogadro’s number. Back to Jeopardy
Constants$200Answer What is the Boltzmann’s Constant? kB =1.38*10-23 J/K Back to Jeopardy

Heat $100Answer What is Heat? The form of energy that is transferred between two substances because they have different temperatures. Back to Jeopardy
Heat $200Answer What is Internal energy? The sum of the kinetic and potential energies of all the atoms and molecules in a substance. Back to Jeopardy
Heat $300Answer What is meant by thermal expansion? The size of an object will change due a temperature Usually, increasing temperature but cause an increase in size. L = LOT where = thermal coefficient in 1/OC Back to Jeopardy
Heat $400Answer Temperature at which water has the greatest density. 4 OC The density of water decreases as water cools from 4OC to 0OC. Back to Jeopardy
