Gas thermometry safety rules

Before starting the experiment, there are some key safety issues to aware of:

• Safety glasses must be worn at all times.

• Move the “dipper” from each reservoir slowly since the temperature changes involved in this lab are extremely large. The dipper is fragile.

• Wear gloves while handling cold and hot items, and do not handle any hot or cryogenic items directly.

• The power to the hot plates which boil water is controlled by a variac. Do not exceed 120V on the variac.

• If you or your partner are uncomfortable moving the cylinder/container from each of the reservoirs, ask the teaching assistant or the technician for help.

• Liquid nitrogen is extremely cold. Handle liquid nitrogen with respect.
