Question

Given below are two statements:

Statement I: Gallium is used in the manufacturing of thermometers.
Statement II: A thermometer containing gallium is useful for measuring the freezing point (256 K) of brine solution.

In the light of the above statements, choose the correct answer from the options given below:

Canvas Classes · Accepted Answer

Strategy:
 Evaluate both statements about Gallium's use in thermometers.

Step 1: Statement I — Gallium in Thermometers
Gallium has a melting point of 302.9 K (~29.9 °C) and boiling point of 2477 K — an enormous liquid range. Because Ga remains liquid over a much wider range than Hg, it IS used in high-temperature thermometers. ✅ Statement I is correct.

Step 2: Statement II — Measuring Freezing Point of Brine
Brine freezes at ≈ 256 K (≈ −17 °C). Gallium solidifies above 303 K — it would be soli
