• Low specific heat
Question 3 - 40
• Explain how the transfer of heat energy when
you put ice in a drink to cool it off
Answer 3 – 40
• heat is transferred from the warmer drink to
the cooler ice.
Question 3 - 50
• The diagram represents two blocks whose
temperatures are indicated by thermometers.
Use the diagrams to answer the questions
below.
• In which direction will the heat
move between blocks A and B in?
• At what point will the heat transfer between
blocks A and B stop?
Answer 3 – 50
• Heat will move from block A to B.
• Heat transfer will stop when blocks A and B
reach the same temperature, called thermal
equilibrium.
