Entropy is the measure of disorder/randomness of particles.

S of solid state < S of liquid state < S of gas state
As temperature increases, the entropy also increases because temperature is the average kinetic energy of the particles..

so let's analyze your choices:
Which one has a higher entropy, Ice or water?

let me rephrase my question, which one has a more random particles, ice or water?

anonymous · Answer

@eliana2480 still there?

anonymous · Answer

@Chibi_Robo3 yes. sorry

anonymous · Answer

no worries :) So which one, water or ice?

anonymous · Answer

water has more random particles

anonymous · Answer

so the answer would be a cup of water at 50 °C?

anonymous · Answer

yes great :) you got it !
