Question 55

Match each description with the correct state of matter.

X: Particles are closely packed but randomly arranged, and are free to move and slide past each other.
Y: Particles are far apart from each other, highly disordered, and move rapidly in random directions.
Z: Particles are held tightly in a regular lattice and can only vibrate about fixed positions.

Write the correct letter (X, Y, or Z) for each state of matter:

Solids: $____\text{\_\_\_\_}$
Liquids: $____\text{\_\_\_\_}$
Gases: $____\text{\_\_\_\_}$

A student heats a block of ice initially at $−5∘C-5^\circ\text{C}$ . They measure the temperature every minute. They heat the ice for 4 minutes until it begins to melt, and then continue to heat it for a further 6 minutes while it is undergoing melting.

Describe and explain how the temperature of the ice changes during the 10 minutes.
