diagrams a, b, and c show the arrangement of particles in a solid, liquid, and gas. diagram b represents the particle arrangement for a gas.

Explanation:

For the first question, when glass is broken, only its shape changes and the chemical properties of the fragments remain the same. This is a physical change as no new substances are formed. For the second question, in a gas, particles are far - apart and move freely. Diagram C shows widely spaced particles, while diagram B shows closely packed particles like in a solid.

Answer:

1. C. a physical change
