Which of the following materials is diamagnetic in nature? MCQ with Answer and Explanation

Explanation:
At boiling point, supplied heat (latent heat) breaks intermolecular bonds for phase change, not increasing kinetic energy (temperature). Potential energy increases while kinetic energy (temperature) stays constant. Memory aid: 'Latent heat changes state, not temperature'. Conceptual question testing phase change understanding, common in competitive exams to assess microscopic interpretation.

Explanation:
In the SI system of prefixes, 'Peta' stands for 10^15. Other common large prefixes include Kilo (10^3), Mega (10^6), Giga (10^9), Tera (10^12), and Exa (10^18). It's crucial to memorize both positive and negative powers (like nano, pico, femto) for competitive exams.

Explanation:
Water has a specific heat capacity of 4184 J/kg·K, which is very high. This means it heats up and cools down much more slowly than land. During the day, land heats faster than the sea, causing air above it to rise and cool air from the sea to rush in (sea breeze). The reverse happens at night (land breeze).
