Is the thermometer reading the temperature of the vacuum at the Moon's surface?
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.
If thermometer is placed in sun light then which thing it will read the temperature of air or of sun or surrounding?
surroundings
Why is it best to take temperature readings in the shade?
A thermometer is not kept in direct sunlight because the temperature needed to be recorded by the thermometer is of the air and not the rays of the sun.
When thermometer is laid ouside the sun does it measure suns temperature or air temperature?
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.
What is a Nuremberg Sun dial?
a protable sun dial
What was used to prove that the earth rotates?
One method that was used by the early Greeks was the Sun Dial.
When was Sun Dial created?
Sun Dial was created in 1990.
What is being measured by an outdoor thermometer?
If it's in the shade, then the temperature of the air that wafts past it is. If it's in direct sun, then it's displaying the temperature of the structure of the thermometer itself, as it absorbs direct solar radiation and its temperature rises above that of the air that wafts past it.
How do scientists know how hot the sun is?
they use a special thermometer to help them test and evaluate how hot the temperature of the sun is and came up with 27 million degrees (F) atthe core.
How you can measure the temperature of the sun?
You certainly can't take a thermometer there - any thermometer will vaporize rather quickly at the high temperatures of the Sun. The temperature of the Sun's surface (the visible part) can be calculated on the basis of the light emitted by the Sun - especially by analyzing the Sun's spectrum. At a different temperature, it would emit a different mix of wavelengths. The temperature in the Sun's core has to be calculated theoretically, on the basis of our knowledge of physics. The Sun's diameter, its mass, the age of the Solar System (estimated by the age of the Earth) and the Sun's composition (what percentage of the different elements it has) all enter this calculation. The composition of the Sun's interior must also be estimated, based on what is visible on the outside. Computer simulations are used in such calculations; the main cause of possible error is our understanding of physics - note that the conditions in the interior of the Sun are very extreme - the temperature is estimated to be several million degrees, and the pressure is very extreme as well.
How Can you tell time by sun?
You can use a sun dial.
What is the plural of sun-dial?
The plural is sun dials.
