Consider the following statements with reference to hot and cold water...
Explanation:
The correct answer is option 'D', i.e., None.
Explanation:
1. Cold water freezes faster than hot water: This statement is false. In reality, hot water freezes faster than cold water, contrary to the commonly held belief that cold water freezes faster. This is known as the Mpemba effect.
2. The phenomenon or effect is known as Mpemba Effect: This statement is true. The Mpemba effect is a phenomenon in which hot water freezes faster than cold water under certain conditions. The effect is named after Erasto Mpemba, a Tanzanian student who observed the phenomenon while making ice cream in 1963. The Mpemba effect is not fully understood, but several theories have been proposed to explain it. For example, one theory suggests that hot water evaporates faster than cold water, which reduces the volume of water that needs to be frozen, thus speeding up the freezing process.
Conclusion:
Therefore, both statements are not correct.
