2. Stopper (plug) - Wikipedia

   en.wikipedia.org/wiki/Stopper_(plug)

   For instance, if one were to boil water in a test tube and wanted to collect the water vapor, one could seal the test tube with a stopper with holes in it. With tubing inserted into the hole(s), when the tube is heated, water vapor will rise through the hole, make its way through the tubing, and into the collection chamber of choice.

3. Teapot effect - Wikipedia

   en.wikipedia.org/wiki/Teapot_effect

   The teapot effect, also known as dribbling, is a fluid dynamics phenomenon that occurs when a liquid being poured from a container runs down the spout or the body of the vessel instead of flowing out in an arc. [1] Markus Reiner coined the term "teapot effect" in 1956 to describe the tendency of liquid to dribble down the side of a vessel while ...

4. Plug (sanitation) - Wikipedia

   en.wikipedia.org/wiki/Plug_(sanitation)

   Plug for a sink. A plug in sanitation is an object that is used to close a drainage outlet firmly. The insertion of a plug into a drainage outlet allows the container to be filled with water or other fluids. In contrast to screw on caps, plugs are pushed into the hole and are not put over the hole.

5. Thermal reservoir - Wikipedia

   en.wikipedia.org/wiki/Thermal_reservoir

   A thermal reservoir, also thermal energy reservoir or thermal bath, is a thermodynamic system with a heat capacity so large that the temperature of the reservoir changes relatively little when a significant amount of heat is added or extracted. [1]

6. Plumbing fixture - Wikipedia

   en.wikipedia.org/wiki/Plumbing_fixture

   In some occasional cases, a sink may have both a potable (drinkable) and a non-potable water supply. Lavatories and water closets normally connect to the water supply by means of a supply , which is a tube, usually of nominal 3/8 in ( United States ) or 10 or 12 mm diameter ( Europe and Middle East ), which connects the water supply to the ...

7. Convection (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Convection_(Heat_transfer)

   For example, when water is heated on a stove, hot water from the bottom of the pan is displaced (or forced up) by the colder denser liquid, which falls. After heating has stopped, mixing and conduction from this natural convection eventually result in a nearly homogeneous density, and even temperature.

8. Isochoric process - Wikipedia

   en.wikipedia.org/wiki/Isochoric_process

   If an ideal gas is used in an isochoric process, and the quantity of gas stays constant, then the increase in energy is proportional to an increase in temperature and pressure. For example a gas heated in a rigid container: the pressure and temperature of the gas will increase, but the volume will remain the same.

9. Negative thermal expansion - Wikipedia

   en.wikipedia.org/wiki/Negative_thermal_expansion

   Ordinary ice shows NTE in its hexagonal and cubic phases at very low temperatures (below –200 °C). [9] In its liquid form, pure water also displays negative thermal expansivity below 3.984 °C. ALLVAR Alloy 30, a titanium-based alloy, shows NTE over a wide temperature range, with a -30 ppm/°C instantaneous coefficient of thermal expansion ...
