Question
Why is there no change in temperature during a phase change, even if energy is
absorbed by the system?
The energy is used to break bonds between particles, and so increases the potential energy of
the system’s particles
The energy is used to break bonds between particles, and so does not increase the potential
energy of the system’s particles
The energy is used to break bonds between particles, and so does not increase the kinetic
energy of the system’s particles

Answer
The energy during a phase change is used to break bonds between particles, which does not increase the particles’ kinetic energy, so the temperature remains constant.

During a phase change, such as melting or boiling, energy is absorbed to break the intermolecular bonds that hold the particles together. This energy goes toward increasing the potential energy of the particles rather than raising their kinetic energy, which is why there’s no observable change in temperature. Essentially, the system is investing energy into changing its structure instead of speeding up; it’s like saving money to buy a house instead of spending it on a vacation!
In real-world examples, this principle is vividly seen in ice melting into water. While the ice absorbs heat, causing the temperature to stay constant at 0°C, it’s busy transforming into liquid water. This phenomenon also helps regulate Earth’s climate; bodies of water can absorb significant amounts of heat during phase changes, smoothing temperature fluctuations and creating a more stable environment for life. So, the next time you’re enjoying a cool drink on a hot day, remember that the ice is doing its job of keeping things chill!
