$\huge{\boxed{\boxed{\underline{\rm{\pink{AnSwEr}}}}}}$

Explanation:

Hopes apparatus consists of a long cylindrical jar with two openings on the side, one near the top and the other near the bottom to fit thermometers in each of these openings. A metallic cylindrical air-tight trough with an outlet is also fitted onto the jar, on its central portion. Now the cylindrical jar is filled with water. The cylindrical trough at the central portion of the jar is filled with a freezing mixture of ice and common salt. After a period of time the more dense water collects at the bottom at a temperature of 4C showing the anomalous behaviour of water.
