No. The thermometer measures the temperature of mass or material. Concerning
the moon, a thermometer could measure the temperature of dust or rock on the
surface. If it were not in contact with the surface, and the sun shone on it, the
thermometer would read the temperature to which the sun heated it. If it were
shielded from the sun, then the thermometer would read the temperature of
space ... about 3 K, or darn near absolute zero.
What else can I help you with?
Why does mercury not flow down when the mercury thermometer is held upside down?
Mercury is a dense liquid at room temperature, so gravity is not strong enough to overcome the surface tension and adhesion forces holding it in place inside the thermometer tube. This allows the mercury to "stick" to the walls of the tube and not flow down when the thermometer is turned upside down.
The color of a vacuum flask in the inside?
The inside of a vacuum flask is typically silver or metallic in color. This reflective surface helps to maintain the temperature of the contents by reflecting heat back into the flask or minimizing heat transfer through radiation.
Why doesn't the liquid in the thermometer move when you turn it upside down?
The liquid in a thermometer does not move when turned upside down because of the properties of the liquid used (usually mercury or alcohol) and the vacuum-sealed tube design of the thermometer. This design prevents the liquid from freely moving when the thermometer is inverted.
How do you measure pressure in the vacuum dryer - by bar or by temperature?
vacuum is a volume of space that is essentially empty of matter, such that its gaseous pressure is much less than atmospheric pressure. The word comes from the Latin term for "empty".Now, u tell me if u measure it by BAR or temp?Though T is directly proportionate to P, measurement of pressure with temperature in a vacuum cleaner is an absurdist theory.
What is the actual use of six thermometer?
It consists of a U-shaped glass tube with two separate temperature scales set along each arm of the U. One of these is for recording themaximum temperature encountered and the other for the minimum temperature. The arms of the U-shaped tube terminate in sealed glass bulbs. The bulb at the top of the minimum reading scale arm is full of alcohol, the other contains a vacuum (or low pressure alcohol vapour). [1] [2] In the bend of the U is a section of mercury. This is pushed around the tube by the thermal expansion and contraction of the alcohol in the first bulb as it responds to the external temperature. The near vacuum in the other bulb allows free movement of the alcohol and mercury. It is the alcohol which measures the temperature; the mercury indicates the temperature reading on both scales. The thermometer shows a reading at the top of the mercury section on both the maximum and minimum scales; this shows the current temperature The maximum and minimum readings are recorded by two small steel markers which are sprung into the capillary tube so that they cannot easily slide unless a small force is applied to them. Before a maximum or minimum reading can be taken, both markers must be returned to the top of the mercury, usually by hand using a small magnet to slide them along the tube. Any change in temperature after that time will push one of the markers along with it. If the temperature is rising, then the maximum scale marker will be pushed. If it falls after the reset, then the moving mercury will push the minimum scale marker. Often both things happen one after another as the temperature changes, say through a twenty-four-hour period (see diurnal temperature variation). The markers thus record the furthest point reached by the mercury in each arm of the tube. They record the extremes of temperature experienced by the device since it was last reset. The thermometer is usually reset every day, but if left for longer the readings would show the highest and lowest temperatures encountered since the instrument was last reset. To take a reading, the positions of the ends of the markers nearest to the mercury are examined. Their positions on the maximum and minimum scales show the highest and lowest temperatures encountered over the period of measurement
What is the Temperature of thermometer when kept in vacuum?
A thermometer will completely drop when in a vacuum as there is nothing in a vacuum, so there will be no energy. A thermometer measures heat energy around it. You may find it'll measure the heat energy that it has itself. In a vacuum, a thermometer cannot measure temperature via convection heating. Hot air or hot gas can't heat up the bulb or bimetal strip or whatever it is that responds to the heat to make the device work. It will measure some heat because infrared (and other electromagnetic) radiation can warm the device. Depending on the circumstances, it will give some kind of reading, but as to what that reading is, we cannot know without knowing what is in or around the vacuum. Even in deep space there is cosmic background radiation everywhere and the temperature is about 3 K, or −270 °C (−454.00 °F).
What is the proper way to take the temperature of vacuum packed food?
The proper way to take the temperature of vacuum packed foods is with a metal stem thermometer. To take the correct temperature, put the thermometer in the center of the food.
What is the right way to measure the temperature of MAP or vacuum-packed foods?
The proper way to take the temperature of vacuum packed foods is with a metal stem thermometer. To take the correct temperature, put the thermometer in the center of the food.
How do you know when the catalityc is pluged?
A noticeable lack of power and performance. Using a vacuum gauge attached to a manifold vacuum source, you notice a drop in vacuum as the rpms are increased while in park. Also, using a surface temperature gauge, after a long drive take a temp reading just before the cat and again after the cat, a plugged cat will have a hotter reading before the cat, a healthy cat will have a hotter reading after the cat.
Is there inert gas inside a thermometer?
No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.
How the liquid in a thermometer changes so that it can be sued to measure temperatures?
The thermometer is a sealed glass tube containing mercury in a vacuum. The mercury column will rise or fall due to expansion, and the level is read off a temperature scale.
Why does mercury not flow down when the mercury thermometer is held upside down?
Mercury is a dense liquid at room temperature, so gravity is not strong enough to overcome the surface tension and adhesion forces holding it in place inside the thermometer tube. This allows the mercury to "stick" to the walls of the tube and not flow down when the thermometer is turned upside down.
What do understand by thermometer?
A thermometer is an instrument, usually mercury in a vacuum inside a transparent glass tube, that is used to measure temperature. As the level in the mercury column rises and falls according to the surrounding temperature, a scale etched onto the glass is read. There are many types of thermometers according to the use they are put to.
What will happen if vacuum in surface condenser is very high?
If the vacuum in the surface condenser it very high, it results in higher practical thermal efficiency. It is important for you to keep the temperature to 100 Celsius or lower for it to work properly.
What is the function of the silvered surface in a vacuum flask?
The silvered surface in a vacuum flask helps to reflect heat back into the container, reducing heat transfer by radiation. This helps to maintain the temperature of the contents inside the flask by minimizing heat loss or gain.
What is the vacuum on 96vortex 350?
18 to 21 inches of vacuum is a normal reading on a vacuum gauge.
What is the temperature inside of a vacuum?
In a vacuum temperature is inapplicable. Temperature is a measure of the kinetic energy of the molecules that fill a defined space. In a vacuum there are no molecules so --- no temperature.
