What are the errors in the use of thermometer?
A thermometer must be calibrated before use to avoid false readings.
Why lab thermometer do not have kink?
the temparature of the liquid must be read while the thermometer is in the liquid.since the level of mercury drops as soon as the thermometer is taken out of the liquid ,therefore no need of the kink in thermometer.
What conditions must be met in terms of density of a body for it to float submerged in water?
A body whose total density is greater than that of water will sink in water;that is, if it's not supported, it will continuously drift lower.A body whose total density is less than that of water will float in water; that is,it will sink only partially, and will then remain on the surface and sink no lower.A body whose total density is exactly equal to that of water will have "neutral buoyancy",and will "float submerged" so to speak. That is, none of it will remain above the surface,but once submerged, it will neither rise nor sink further, but will maintain the depth at whichit is placed.
What is the density of thing if does not seettle in water?
The density of a solid not completely submerged in water is less than 1 gram per milliliter, the density of water. Only the volume of the submerged portion will displace the water and the portion on floating above the level of water cannot be measured.
What does the intensity of light bulb indicate?
It indicates that the light bulb must be high of voltage trough the current......
In getting the temperature of tap water why must the bulb of the thermometer be submerged in the water?
Because you need to measure the temperature of water, not the air.

Why must the sling psychrometer be swung to obtain the wet bulb reading?
It is swung through the air to speed up evaporation of water from the wet bulb thermometer.
Why must sling psychrometer be swung in order to obtain the wet bulb reading?
It is cooling by evaporation
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.
What will the mercury thermometer show when it is kept in ice?
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
Do reptiles hatch their eggs under water?
No. Reptiles must lay their eggs on land. If a reptile egg is submerged in water the embryo will drown.
Why is the entire mercury bulb of the thermometer must be below the level of the side arm in order to obtain an accurate reading of the distillation?
The boiling point of the distillate is normally the temperature of the vapour. If the bulb of the thermometer is placed too high, above the sidearm leading to the condeser, the entire bulb will not be heated up by the vapour of the distillate, and the temperature will be too low. however, if the bulb of the thermometer is placed too low, too near to the surface of the boiling water, the thermometer will show a too-high reading.Thus, the bulb of the thermometer should be placed at the sidearm or just below the sidearm in order to obtain an accurate reading of the distillation.

Parts of a liquid-in-glass thermometer?
AnswerThere are a number of different types of thermometers, but all have two basic elements. First, they must have a temperature sensor (mercury, dissimilar metals, etc.) capable of detecting a change of temperature. Second, they must have a means (such as a scale) of measuring the degree of change.AnswerAlso there's a bulb isn't there? So there are: bulb, scale, colored alcohol (or w.e).
What do stonefly nymphs eat?
Stonefly nymphs mainly feed on leaves and algae. They must be submerged in the water though in order for the nymphs to eat them.
Why does the clinical thermometer have a constriction?
Quote: When the temperature falls, the column of mercury breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube. After reading the value, the thermometer must be reset by repeatedly swinging it sharply to shake the mercury back through the constriction. Unquote.
