Energy Interaction and Phase Change Quiz

What is the purpose of the temperature versus energy-added diagram in the three-phase model of matter?

• To determine the color of a substance

• To measure the mass of a sample

• To calculate the energy needed for temperature changes and phase transitions

• To identify the chemical composition of a material

In the energy interaction diagram example, what is the initial temperature of the ice cube?

• 100 degrees Celsius

• -196 degrees Celsius

• 0 degrees Celsius

• 25 degrees Celsius

Why is the system considered closed in the ice cube and ice water example?

• Because it is in an open container

• Because heat is exchanged with the surroundings

• Because no heat is lost to the surrounding air

• Because it involves a chemical reaction

What is the indicator for bond energy in the energy interaction diagram?

• The mass of the liquid water

• The volume of the container

• The color of the ice

• The pressure of the system

What happens to the bond energy of the ice water as the amount of liquid water decreases?

• The bond energy remains constant

• The bond energy increases

• The bond energy fluctuates randomly

• The bond energy decreases
