Why does liquid inside a thermometer rise as the temperature s increase?
Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.
When an ice cube in a glass of water melts the water level in the glass?
increases
Why is Mercury used in thermometeres?
Mercury is a liquid over a wide range of temperature ( -39 to 357 degrees ) so it can be used in a variety of temperature ranges. Secondly it does not stick to the glass tubing of the thermometer so when the temperature falls ( i.e. after the reading is taken) all the mercury falls back into the reservoir. This ensures the accuracy of the mercury thermometer.
Which way does the light change direction when it goes into the glass block?
bends upward
What happens to kenetic energy as temperature increases?
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
Why is it necessary to use only one direction in cutting a glass tubing?
Cutting in one direction in glass tubing will reduce the places the glass will crack and break. Cutting in multiple directions greatly increases the chance of the glass tubing completely shattering when you break it off.
What is glass tubing and how is it used?
Glass tubing is exactly what it sounds like -- a tube made of glass. Glass tubing comes in all shapes in sizes, with tube diameters or just a millimeter or less up to very large tubes. It can be used for a number of things. I can be used to carry both liquid and gasses. With a triangular file, it is possible to break glass tubing into smaller pieces. Using a hot flame from a Bunsen burner, it is possible to bend glass tubing into other shapes.See the Web Links to the left for more information about how to use glass tubing.

How do you cut glass tubing?
with a quarter stick

What lab apparatuses hold glass tubing?
This is a stand.
Ordinary glass is filled to the brim with water If the temperature decreased how much water could be added to the glass?
It depends on: -The current temperature of the water. (If it was already cold, the water would probably decrease because both heat and cold causes water to increases) -The size of the glass. -How much the temperature decreases.
How dangerous is florscent tubing?
It isn't dangerous until the glass breaks. Broken glass is dangerous. The contents inside the tubing may contain mercury or other chemicals that should not be ingested.
What are the three different ways colored lights can be produce in neon tubing?
1. - Clear glass tubing with neon produces red or reddish-orange; Clear glass tubing with argon produces faint purple. 2. - Some colors are produced by inert gases in tubing with fluorescent powders painted or baked on the inside. 3. - Colored glass may be used in combination with neon or argon, Mercury, and helium to produce other colors
What is the function of the glass tubing?
The function of a hard glass test tube is heating a substance. The glass is resistant to chemicals and it can withstand pressure and heat.
What has one hole and can hold glass tubing?
A glass, beaker, flask, jar and anything else that has a hole on top.
Why must the glass tubing be wrapped with a cloth or paper towel before breaking?
This is a safety precaution to prevent injury to the experimenter's hands. Glass tubing may splinter or shatter if scored incorrectly or if there was a defect in manufacturing.
