10. What is a magnet? A: A magnet is an object that produces a magnetic field and can attract or repel certain materials and other magnets.
11. What is a magnetic field? A: A magnetic field is the region around a magnet or moving electric charge where magnetic forces can be felt, represented by field lines from north to south.
12. Describe the properties of a magnet. A: A magnet has north and south poles, produces a magnetic field, attracts ferromagnetic materials, and shows attraction between opposite poles and repulsion between like poles.
13. Describe how magnets affect a compass needle. A: A magnet’s field exerts a torque on a compass needle, causing it to rotate and align with the magnetic field direction (its north end pointing toward the Earth's magnetic south).
14. How does an MRI machine work? A: MRI uses strong magnetic fields and radiofrequency pulses to align and perturb hydrogen nuclear spins and detects the emitted signals as they relax to form detailed internal images.
15. Define Temperature. A: Temperature is a measure of the average kinetic energy of the particles in a substance.
16. Describe the potential and kinetic energy of atoms. A: Atoms have kinetic energy from motion (translation, rotation, vibration) and potential energy from their positions and interactions (bonds and intermolecular forces).
17. How is thermal energy different from temperature? A: Thermal energy is the total internal energy (sum of kinetic and potential energies) of all particles in a system, while temperature measures the average kinetic energy per particle.
18. What happens to temperature when a substance is going through a phase change? What is happening to the particles and what is being done with the energy? A: During a phase change the temperature remains constant while added energy changes particles' potential energy to rearrange or break intermolecular bonds (changing phase) rather than increasing kinetic energy.
19. Sketch a temperature time graph of water going from a solid to a gas phase. A: A heating curve: temperature rises in the solid region, plateaus at 0°C during melting, rises in the liquid region, plateaus at 100°C during boiling, then rises in the gas region.
11. What is a magnetic field? A: A magnetic field is the region around a magnet or moving electric charge where magnetic forces can be felt, represented by field lines from north to south.
