When a thermometer bulb containing Mercury is placed in hot water, the mercury inside expands, causing the level of mercury to rise. This expansion of mercury is used to measure the increase in temperature accurately.

What will happen to a light bulb when its in water and placed in a microwave?

Placing a light bulb in water and then microwaving it is extremely dangerous and not recommended. The water could heat up rapidly and cause the light bulb to explode, potentially resulting in dangerous shards of glass and electrical components being scattered. It can also cause electric shock hazards.


Can a metal halide bulb be used in the place of a mercury vapor bulb?

No, metal halide bulbs and mercury vapor bulbs are different types of lighting technology with varying operating requirements. Using a metal halide bulb in place of a mercury vapor bulb can result in inefficient operation and potentially damage the fixture. It is best to use the type of bulb specified by the manufacturer for optimal performance.


Is the external bulb of a thermometer also made of mercury?

No, the external bulb of a thermometer is typically made of glass to hold the mercury inside. Mercury is usually contained within the glass bulb to measure temperature accurately without exposing the user to the toxic substance.


You cut yourself with a compact fluorescent light bulb is there a chance you may get mercury poising?

Is there a chance of mercury poisoning? Yes, but it is a very, very, very small chance (so small it is barely worth mentioning). Wash the cut with a little soap and water and you should be just fine.


Why the Mercury-in-glass thermometer first descends and then rise when put in flame?

When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.

Why does mercury level goes down for a very short time when a mercury-in glass thermometer is placed in hot water?

The exterior of the bulb of the thermometer expands first, resulting in the mercury level to go down. After that the mercury in the bulb expands more than the glass bulb, resulting in the subsequent rise of the mercury level.


Why a column of mercury in theromometer first descends slightly and then rises when placed in hot water?

When a thermometer is placed in hot water, the heat causes the liquid inside (mercury in this case) to expand. This expansion initially pushes the mercury down slightly due to increased pressure. However, as the mercury absorbs more heat, it expands further and eventually rises to reflect the higher temperature of the hot water.

What will happen if you hold a mercury thermometer from its bulb?

If you hold a mercury thermometer from its bulb, the heat from your hand can cause the mercury to expand and rise in the tube, giving an inaccurate reading. Additionally, mercury is toxic, so it is not safe to handle a broken thermometer. Always handle thermometers by the plastic casing to avoid these issues.


Does the bulb placed in series with bulb lightens with dc?

yes we can bulb placed in series with dc


Why does bulb of a clinical thermometer break when placed in very hot water?

The bulb of a clinical thermometer breaks when placed in very hot water because the sudden increase in temperature causes the air inside the bulb to expand rapidly. This rapid expansion of air creates pressure within the bulb, leading to its breakage.


Pressure bulb can you use a sodium bulb in a mercury fixture?

no


What do you need to make a wet bulb theremometer?

A wet bulb thermometer, simply has the sensitive bulb, dampened with water.A small muslin bag with wick attached, is placed over the bulb. The wick is placed in a small container of water, which must be periodically topped up.The water around the bulb evaporates, giving a cooling effect. As the water evaporates, more is drawn via the wick from the reservoir.The amount of evaporation, will depend on the water saturation already in the atmosphere. By comparing the temperature with a normal thermometer and reading the results in a table, the dew point can be found.


Why must the bulb of the thermometer be submerged in the water?

The bulb of the thermometer must be submerged in the water because that is where the temperature of the water is accurately measured. The bulb is the part of the thermometer that contains the temperature-sensitive material, such as mercury or alcohol, which expands or contracts depending on the temperature of the water. This expansion or contraction is then displayed on the thermometer scale, giving an accurate reading of the water temperature.


What is the fluid in a fluorescent light bulb?

In a fluorescent light bulb there is usually a drop of mercury. That mercury vaporizes as the bulb warms up and it becomes gaseous, enhancing the electron interaction through the bulb, making it brighter.


What are the Sources of error in distillation?

boiling chips are not added to the distillation flask. the thermometer bulb is placed in the boiling liquid. the water to the water-jacketed condenser is not turned on.


What does the gas discharge bulb contain?

Mercury.
