Increased movement of the particles in a solid comes from increased ________.

• A. temperature
• B. density
• C. volume
• D. pressure

Answer: (A)

Verified step by step guidance

1. Understand that the movement of particles in a solid is related to their kinetic energy, which depends on temperature.
2. Recall that temperature is a measure of the average kinetic energy of particles in a substance.
3. Recognize that increasing temperature causes particles to vibrate more vigorously within their fixed positions in the solid lattice.
4. Note that density, volume, and pressure affect physical properties but do not directly cause increased particle movement in a solid.
5. Conclude that increased movement of particles in a solid comes from increased temperature.
