Why do you sterelize the clinical thermometer with antiseptic solution before you use it?
So that you do not introduce germs to the person whose temperature is to be measured.
How is temperature taken through an oral placement?
The procedure for taking a patient's temperature by mouth with a mercury thermometer is similar to the axillary method except that the silver tip of the thermometer is placed beneath the tongue for four to five minutes before being read.
Why does the doctor dip the thermometer in a liquid before use?
it is alcohol to disinfect the thermometer
Where should a thermometer be placed in a beaker?
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
Why must an evaporating dish cool before measuring its mass?
Temperature only effects mass by a very little amount. A high school lab including chemical reactions and using a scale that measures to the hundredth or thousandths place won't be effected by temperature. One reason that you must wait for the dish to cool could be for safety precautions, or possibly just to prevent damage to the scale. It all depends on the situation.
Why do you sterelize the clinical thermometer with antiseptic solution before you use it?
So that you do not introduce germs to the person whose temperature is to be measured.
What do you do before taking an axillary temperature?
Shake down the thermometer before using, if the reading on the thermometer is 94.0º F or above.
What did farhrenheit do for science?
Fahrenheit created the first thermometer for measuring temperature. Before he created his thermometer, people did not have a precise way to describe temperature.
Why don't thermometers read down to -300 degrees Celsius?
Well, first of all, absolute zero, the point at which there is no thermal energy is at -273 degrees Celsius, so nothing could ever get to -300 C. Also, the mercury in the thermometer would freeze long before absolute zero, and it is unlikely that a standard thermometer would ever be used below its minimum measurement. If temperature measurement was needed below the minimum measurement of a thermometer, specialized scientific thermometers are available.
What is meant by the statement a thermometer measures its own temperature?
When a thermometer reaches thermal equilibrium, the temperature of the thermometer and the substance it is measuring are the same. Therefore, the thermometer is essentially measuring its own temperature.
Why does the thermometer dipped in water before use?
to bring the temperature to the normal position.
Why is it necessary to warm the thermometer before placing it into the solutions?
The thermometer reading will change from reading the solution temperature.
Why dips the thermometer in an liquid before use?
Dip it in achahol so it can get rid of germs.
How can you prove that temperature increases during chemical reaction?
Measuring it before, after and during the reaction with a thermometer.
What was the jow a measurement for in India before it got obsolete?
The jow, or jacob, was a measurement used in India until the mid-20th century and measured about a quarter of an inch. It was replaced by metric measurement.
How do you take the reading of a thermometer?
After the thermometer has come into thermal equilibrium with the object being measured, the top level of the liquid (mercury or alcohol thermometer) is the temperature. The indicators will often also be colored red on mechanical (coil expansion) thermometers. Digital thermometers should be "locked" at the recorded temperature if the probe is to be removed before viewing, as it may heat or cool even during a very short interval.
What are precautions that are to taken while measuring the temperature in clinical thermometer?
the mercury should be at normal body temperature level before using it the thermometer should be cleaned after use with normal water the bulb of the thermometer should not be touched
