The statements outline two changes of state. 1 The molecules of substance X are in a random arrangement. As the change of state occurs, they lose energy and become more ordered, although the molecules can still move freely. 2 The molecules of substance Y are in a regular lattice. As the change of state occurs, they gain energy and become less ordered, while the molecules remain close together. Which changes of state are described in the statements?
- Acondensation and evaporation
- Bcondensation and melting
- Cfreezing and evaporation
- Dfreezing and melting
