If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL ____________

• one reaches a temperature of zero

• they both have an equal temperature

• one runs out of energy

Observe the diagram. Which statement is true about the kinetic energy of the molecules in the containers?

• The molecules are moving faster in Diagram A

• The molecules are moving slower in Diagram A

• The molecules are moving at the same rate in both diagrams

There are four cups of hot cocoa. The cup sizes are shown. The temperature of the cocoa in each cup is 25 degrees celsius. Which cup has the MOST thermal energy?

• Large cup (Trenta)
• Small cup (Tall)
• Venti
• All three are the same temperature so they have same thermal energy
