The kinetic energy of particles is generally associated with temperature—the higher the temperature, the greater the average kinetic energy of the particles.
Among the options provided, the case where the kinetic energy of particles would be increasing is:
**C: Metal is heated from room temperature to 200 Celsius.**
In this case, as the metal is heated from a lower temperature (room temperature) to a higher temperature (200 Celsius), the kinetic energy of its particles is increasing.
- **Option A (metal is cold at 1,300 Celsius)** would imply that the metal is actually at a high temperature, and it is not increasing its kinetic energy but is already high.
- **Option B (metal is melted at 1,300 Celsius)** involves a phase change (melting), where the temperature remains constant during the process, so the average kinetic energy change associated with the phase change isn’t increasing in this context.
- **Option D (metal is at room temperature 37 Celsius)** does not involve an increase in temperature.
Thus, option C is the correct choice.
