1. Assignment:
Please read the text and answer the questions that follow it:
A ring stand is probably the handiest single support you can own. It can be used to hold a funnel or to support a flask, beaker or crucible over a flame.
A tripod may be substituted for a ring stand. This three-legged iron stand may have a single ring for a top or it may have several concentric rings which can be removed or added to suit the size of the apparatus to be heated.
If you have a supply of gas in your lab, a Bunsen or a Fisher burner will solve practically all your heat problems. If you have not, you will have to improvise. A small alcohol lamp will generally do for heating test-tubes. A larger alcohol or gasoline burner or an electric hot plate will heat flasks and beakers. A propane soldering torch, provided with a flame spreader, will give you plenty of heat.
