Why is it in News?
→ JNCASR scientists developed first supercomputer-powered simulations explaining the Mpemba effect.
→ The study resolved long-standing debates in non-equilibrium physics.
Important Points:
- Mpemba effect refers to hotter water freezing faster than colder water.
- First noted by Aristotle in Meteorologica.
- Rediscovered by Erasto Mpemba in the 20th century.
- Study conducted by JNCASR under the Department of Science and Technology.
- Water freezes through intermediate molecular states.
- Hot water can bypass delay phases and nucleate ice faster.
- Effect is not limited to water; applies to other phase transitions.
- Findings aid cooling technologies and thermal control in electronics.
