Which of the following terms describes how far and direction? Heat flow through empty space occurs through which method? A gas heater warms a room mostly through what? Ice melts at what temperature? Which term describes how fast and in what direction? What effect does a refrigerator have on a room? If I walk from point A (0 m) to point B (10 m) in 5 seconds, what is my average velocity?
Understand the Problem
The question is asking which of the provided options is the best answer for each physics-related question. It involves selecting the correct terms related to concepts such as motion, heat transfer, and basic thermodynamics.
Answer
1. Displacement 2. Radiation 3. Convection 4. 0°C 5. Velocity 6. Warms the room 7. 2 m/s
- Displacement describes 'how far and direction.' 2. Radiation is the method of heat transfer through empty space. 3. A gas heater warms a room mostly through convection. 4. Ice melts at 0°C. 5. Velocity describes 'how fast and in what direction.' 6. A refrigerator warms the room. 7. Average velocity is 2 m/s.

More Information
Displacement and velocity both incorporate direction, but velocity also includes speed, making it crucial for describing motion in physics.
Tips
Common mistakes include confusing displacement with distance (which lacks direction) and overlooking that velocity requires both speed and direction.
