4.7 Tell the person next to you...
1. What is the most common heat transfer mechanism in solids? - copper
2. What is the most common heat transfer mechanism in liquids and gases? - convection 3. What is the only heat transfer mechanism in a vacuum? - Radiation
4. Why can't conduction happen in a vacuum? - Because there are no particles 5. What happens to the space between the molecules in a gas when you heat it? - They expand 6. What happens to the density of a gas when you heat it? - It decreases 7. Why can't convection happen in a solid? Because the particles are linked together. Instead it conducts the heat
