Does liquid water rise higher in a narrow tube or a wide tube?
Rise or fall of liquid in a small passage or tube. When a glass tube of small internal diameter is inserted into water, the surface water molecules are attracted to the glass and the water level in the tube rises. The narrower the tube, the higher the water rises. The water is said to "wet" the tube. Water will also be drawn into the fibres of a towel, even if the towel is in a horizontal position. Conversely, if a glass tube is inserted into mercury, the level of the liquid in the tube falls. The mercury does not wet the tube. Capillarity is caused by the difference in attraction of the liquid molecules to each other and the attraction of the liquid molecules to those of the tube.
If heating continues the water in the glass tube will most likely?
If heating continues, the water in the glass tube will eventually turn into steam and expand rapidly. This could cause the glass tube to shatter due to the build-up of pressure.
Why do we heat the test tube in a water bath and not directly over a flame?
so they dont explode Because of the thickness of the glass. Glass that is thin, as in test tubes expand with heat rather quickly and this makes them very fragile. The water bath heats them up slowly.
When heated what happens to ammonium chloride mixed with water in the tube?
When heated, ammonium chloride mixed with water in the tube will undergo decomposition to produce ammonia gas, hydrogen chloride gas, and water vapor. This reaction is endothermic, meaning it absorbs heat from the surroundings. The ammonia gas can be identified by its pungent smell.
How does a percolator produce coffee?
It doesn't, coffee is grown. The way a percolator works is by the change in the density of water when it is heated. Water is placed in the percolator then the riser tube is placed in and the filter cup with ground coffee in it is placed on the top of the tube, ABOVE the top surface of the water. The water is heated at the bottom of the pot, this hot water rises and is directed up the tube, cold water replaces it at the bottom of the pot, this cold water as the density is much higher forces the hot water up the tube where it overflows into the filter basket and percolates back down through the coffee grounds, then back to the pot to be cycled through again. The percolation slows down as the temperatures in the pot equalize, or the water level is lowered.
How far above the lowest permisseble water level is the bottom of the gauge glass in a fire tube and water tube boiler?
3inces
When a mercury therometer is heated the mercury expands and rises in the thin tube of glass What does this indicate about the relative rates of expansion for mercury and glass?
The fact that the mercury expands and rises in the thin glass tube when heated indicates that mercury expands more than glass when heated. This suggests that mercury has a higher coefficient of thermal expansion compared to glass.
What is the effect of breakage of glass tube of water level indicator?
Having the glass tube breaking all the time effects production and creates loss time for the any production unit.

Why does the water level of the liquid in the test tube drop a little first before rising when putting the test tube into the cup of warm water?
The glass expands first, increasing its capacity and lowering the water level. Then water then expands increasing its volume and thereby raising the water level.
How do you know when to bend the glass tube?
You should bend the glass tube when it is heated evenly to a specific point, usually indicated by a color change from the heat. It is important to bend it slowly and steadily to avoid cracking or uneven shaping of the tube. A glassworking torch or flame is typically used for this purpose.
How do scientists form glass parts that they need from glass tubes?
By pulling on both ends of heated glass. The more they pull, the smaller the diameter of the resulting glass tube or capillary.
Water will move higher in a narrow glass tube than in a wide glass tube because of?
It is because of Capillary action, the adhesive forces for water are effective in narrow tube, in a wide tube the weight of water resists the upwards movement of water.
Why does water in a glass tube contracts first then expand when heated?
glass is a bad counductor of heat, so at first the glass flasks expands and its volume inside increases. the liquid which has not started to expand yet, drops to fill the extra volume inside
Why the glass apparatus may break when it washed immediately after heating?
This is mainly due to the difference in temperature. Once glass (let's take a test tube for example) has been heated, the glass itself assumes this temperature also. If you pour or immerse this heated test tube in cold water, it causes the glass to contract; this contraction causes the glass to crack and of course shatter. Glass as you're aware isn't very flexible or elastic and instead is brittle so this happens fairly easily with standard laboratory equipment. Hope this answers your question.
Why when placed in a glass tube water touching the glass is pulled slightly upward?
Meniscus. Essentially it is because water adheres to the glass.
What is an audion?
An audion was an early variety of electronic amplifying tube consisting of a partially evacuated glass tube with three electrodes, a heated filament, a grid and a plate.
