An ice cube is placed in a bathtub at t=0 seconds. after some time interval at-T, the ice cube has melted. At what time is the entropy of the bathtub-icecube system at a maximum?

Respuesta :

An ice cube at 0°C is placed in a very large bathtub filled with water at 30°C and allowed to melt, causing no appreciable change in the temperature of the bath water. The entropy of the system (ice plus water) increases because the process is irreversible will be true

Entropy

  • The entropy of an object is a measure of the amount of energy which is unavailable to do work.
  • Entropy is also a measure of the number of possible arrangements the atoms in a system can have.
  • In this sense, entropy is a measure of uncertainty or randomness.
  • In a reversible process, the entropy of the universe stays unchanged, but in an irreversible (spontaneous) process, the entropy of the universe increases.
  • It also increases during a non-spontaneous process that is measurable.
  • we can not convert water into ice again, hence it must be an irreversible process which implies that entropy will increase

Hence, An ice cube at 0°C is placed in a very large bathtub filled with water at 30°C and allowed to melt, causing no appreciable change in the temperature of the bath water. The entropy of the system (ice plus water) increases because the process is irreversible will be true
