Question

which of the following phase changes is defined as particles colliding randomly and then slowing down and flowing past each other?○ condensation○ freezing○ sublimation○ deposition○ melting○ evaporationquestion 6 3 ptswhich of the following phase changes is represented with the following equation? $co_{2(s)}
ightarrow co_{2(g)}$○ evaporation○ sublimation○ condensation○ melting○ freezing○ deposition

Explanation:

For the first question: Condensation is the phase change where gas particles (moving randomly, colliding) slow down, lose energy, and form a liquid where particles flow past each other.
For Question 6: Sublimation is the phase change where a solid directly transitions to a gas, which matches the equation $\text{CO}_{2(s)}
ightarrow \text{CO}_{2(g)}$.

Answer:

1. condensation
2. sublimation
