Is the apparatus used to measure temperature
Witryna27 lut 2024 · A liquid in glass thermometer is the most commonly used temperature measuring device used in laboratories. This thermometer has a glass bulb attached to a sealed glass tube, known as the stem or capillary tube. A bore, which is a very thin opening, exists from the bulb and extends down the centre of the tube. Witryna1 lut 2024 · Exercise 7.3.3. A coffee-cup calorimeter contains 50.0 mL of distilled water at 22.7°C. Solid ammonium bromide (3.14 g) is added and the solution is stirred, giving a final temperature of 20.3°C. Using the same assumptions as in Example 7.3.3, find Δ Hsoln for NH 4 Br (in kilojoules per mole). Answer: 16.6 kJ/mol.
