FINAL JEOPARDY• ANSWER: Explain how the distance of oil
molecules change from a solid to a liquid. • QUESTION: Expands
QuestionAnswer
A-100• ANSWER: The First Law of
Thermodynamics states that….• QUESTION: What is “Thermal
Energy cannot be created nor destroyed”?
QuestionAnswer
A-200• ANSWER: The First Law of
Thermodynamics is similar to this law…
• QUESTION: What is “The Law of Conservation of Energy”?
QuestionAnswer
A-300
• ANSWER: The Second Law of Thermodynamics states that….
• QUESTION: Heat is transferred from Hot molecules to cold molecules
QuestionAnswer
A-400• ANSWER: I hold an ice cube in my
hand. Explain the heat transfer. • (2 facts)• QUESTION:. The heat is transferred
through conduction and the warmer molecules of my hand is transferring their energy to the cold ice molecules causing it to melt.
QuestionAnswer
A-500
• ANSWER: The Third Law states that molecules are in motion unless its at Absolute Zero. List two facts about this temp.
• QUESTION: 0K, Coldest possible Temp, Molecules have no kinetic energy
QuestionAnswer
B-100• ANSWER: What are the three
forms of heat transfer?• QUESTION: conduction,
convection, radiation
QuestionAnswer
B-200
• ANSWER: Examples:Microwaves, Sun, Heat Lamp, Fire
• QUESTION: Radiation
QuestionAnswer
B-300• ANSWER: Examples:Pot on a stove, ironing clothing, taking a hot bath
• QUESTION: Conduction
QuestionAnswer
B-400• ANSWER: Examples:Hot air balloon rising, boiling soup, rising magma in the mantle
QUESTION: Convection
QuestionAnswer
B-500• ANSWER: When does conduction,
convection and radiation stop?
• QUESTION: When the temperatures reach equilibrium.
QuestionAnswer
C-100
• ANSWER: What is kinetic energy?
• QUESTION: energy of motion
QuestionAnswer
C-200• ANSWER: What is the Kinetic Particle
Theory about?
• QUESTION: All molecules (solids, liquids and gases) are constantly moving.
QuestionAnswer
C-300• ANSWER: When heat is added to
liquid molecules, describe two changes that occurs.
• QUESTION:1. Molecules increase kinetic energy2. Molecules move apart and expand3. The liquid turns into a gas
QuestionAnswer
C-400• ANSWER: Which cup has more
kinetic energy and why? A cup of 70o coffee or a cup of 90o milk?
• QUESTION: 90 degree milk because it has more thermal energy causing the molecules to move faster.
QuestionAnswer
C-500• ANSWER: Explain how water
behaves differently compared to all other forms of matter when it freezes.
• Question: Waters expands when it freezes. All other forms of matter contracts.
• QUESTION:
