To determine in which case the kinetic energy of particles is increasing, we need to consider the temperature conditions and what they imply about the motion of the particles.
1. **A metal is cold at 1,300 Celsius** - At this high temperature, the particles in the metal are moving rapidly, indicating a lot of kinetic energy. Saying the metal is "cold" at this temperature is contradictory.
2. **B metal is melted at 1,300 Celsius** - As a metal melts, the kinetic energy of its particles does increase until it reaches its melting point. However, the melting process also involves the absorption of heat that increases potential energy (not kinetic) during the phase transition from solid to liquid.
3. **C metal is heated from room temperature to 200 Celsius** - Heating a metal means that the kinetic energy of its particles is increasing as the temperature rises.
4. **D metal is at room temperature 37 Celsius** - At a constant temperature, the average kinetic energy of the particles remains the same.
Based on this analysis, the answer is **C: metal is heated from room temperature to 200 Celsius**. In this case, the kinetic energy of the particles is definitively increasing due to the influence of the temperature rise.
