14.1.3. Heat Transfer Considerations

Try these first

1. 1.

   Define extensive property with an example.

   Hint

   Think about properties that change with the amount of material.

2. 2.

   What is the definition of intensive property?

   Hint

   Consider properties that remain the same whether you have a little or a lot.

3. 3.

   What does conservation of mass state?

   • Mass can be created
   • Mass cannot be created or destroyed
   • Mass is variable

   Hint

   Think about closed containers.

4. 4.

   Is heat transfer affected by temperature gradients?

   • True
   • False

   Hint

   Recall the concept of heat flowing from hot to cold.

5. 5.

   A closed container holds water at 100°C. Describe what occurs as heat transfers to the surroundings?

   Hint

   Consider how heat flows and the concept of equilibrium.

6. 6.

   In a system experiencing a change in momentum, derive how the conservation of momentum would apply in a real-life scenario.

   Hint

   Think about forces that can alter velocity.
