Question

label the phases of matter and phase changes that are occurring on the image below.

Explanation:

To solve this, we analyze the phases and phase changes:

Step 1: Identify the top phase (Gas)

The top diagram shows particles with large spacing and random motion, characteristic of a gas (option 3). The arrow from gas to liquid is condensing (option 7, as gas → liquid is condensation).

Step 2: Identify the middle phase (Liquid)

The middle diagram shows particles with moderate spacing and fluid motion, characteristic of a liquid (option 2). The arrow from liquid to gas is boiling (option 4, liquid → gas is boiling/evaporation). The arrow from liquid to solid is freezing (option 6, liquid → solid is freezing).

Step 3: Identify the bottom phase (Solid)

The bottom diagram shows particles closely packed in a fixed arrangement, characteristic of a solid (option 1). The arrow from solid to liquid is melting (option 5, solid → liquid is melting).

Final Labels:

• Top “PHASE:” \(\boldsymbol{\text{Gas (3)}}\); Arrow from gas to liquid: \(\boldsymbol{\text{Condensing (7)}}\)
• Middle “PHASE:” \(\boldsymbol{\text{Liquid (2)}}\); Arrow from gas to liquid (reverse) is not labeled here, but arrow from liquid to gas: \(\boldsymbol{\text{Boiling (4)}}\); Arrow from liquid to solid: \(\boldsymbol{\text{Freezing (6)}}\)
• Bottom “PHASE:” \(\boldsymbol{\text{Solid (1)}}\); Arrow from solid to liquid: \(\boldsymbol{\text{Melting (5)}}\)

(Note: The exact placement of arrows depends on the image’s direction, but the key is matching phase characteristics to solid/liquid/gas and phase change definitions.)
