Question

Obtain a completely dry polypropylene 250 mL Erlenmeyer flask (with wire gauze and safety ring). 2. Set up a hot water bath over a Tirill burner using a ring stand and wire gauze in the water.

Answer 1

To set up a hot water bath, place a polypropylene flask on a stand with wire gauze for support. Add water and heat from below with a Tirill burner. This setup can be related to a calorimeter's construction for heat-measure work in chemistry.

Step-by-step explanation:

You're looking to set up a hot water bath over a Tirill burner with a 250 mL Erlenmeyer flask, made from polypropylene. Polypropylene is a high-density type of plastic that withstands high temperatures, making it suitable for this job. It's complimented by wire gauze and a safety ring for added security.

Begin by securing your flask in place on the ring stand with the wire gauze acting as a support and a diffuser of heat. Next, fill the flask with suitable amount of water. The Tirrill burner underneath the stand will be your source of heat, which can be controlled to desired intensity.

Meanwhile, an example of a similarly simplified setup can be seen in the construction of a simple calorimeter, which consists of two polystyrene cups, a thermometer, and a stirrer penetrating through the cover into the mixture.
