Who invented the infrared fever screening system?
Infrared Fever Screening System used in public buildings to scan for people with a high temperature from a fever or sars invented by Singapore Technologies Electronics and the Singapore Defense Science and Technology Agencyaccording to http://inventors.about.com/od/timelines/a/ModernInvention.htm
What is the temperature of water under the sun in 5 minutes?
That will depend on several factors, including . . . -- The temperature of the water when you take it outside. -- Whether the container holding the water is transparent, translucent, or opaque. -- The thermal conductivity of the material of which the container is made. -- How much water is in the container. -- Whether the continer is sealed or open to the air. -- If the container is open, then the area of the surface of the water exposed to the sun. -- If the container is open, then the speed of the wind across the surface of the water. -- The temperature of the air outside. -- Whether the sky is clear or cloudy. -- Location the experiment is performed. -- How high in the sky the sun is at the time of the experiment, i.e. the time of day. --Density of the air
What is surface temperature?
Surface temperature is the temperature on the outside of the object. For example the surface temperature of the Earth is the Ground temperature and the surface temperature of an orange is the rind not the pips.

What is the temperature of Vega?
Vega has a temperature of about 9,000oK
If an iron rod is heated to a high temperature how would it effect its conductivity?
Generally speaking conductivity of metals decreases as the temperature increases.
What is the conductivity of 1milimole tris buffer?
The conductivity of the tris buffer 1 is found to be 4.0mmho/cm. The conductivity is achieved at a temperature of 27 degrees.
How will molar conductivity vary with concentration or temperature?
molar conductivity involves concentration of electrolyte also....but electrolytic conductivity doesn't
What factor determines how hot or cold something feels when you touch it?
The temperature. Also, thermal conductivity.
How can you increase the conductivity of a semi conductor?
The conductivity of a semi-conductor can be increased by raising the temperature of the semi-conductor .
What factor should change in electrical conductivity of metals and non metals?
Electrical conductivity depends on temperature.
Heat is transferred from an object that has a thermal conductivity temperature to an object that has a?
Heat is transferred from an object that has a thermal conductivity temperature to another object through heat conduction.
Thermal conductivity temperature to an object that has a?
The thermal conductivity temperature of different objects vary from one object to another. When the two objects are placed together, there will be a change in temperature through heat conduction.
Do metals increase electrical conductivity with increasing temperature?
Yes, it does; exactly how it affects the conductivity depends on the metal. As a general rule conductors become LESS conductive as the temperature goes up, while semiconductors become MORE conductive as the temperature goes up.
How do you convert conductivity and temperature to total dissolved solids TDS?
E. Conductivity(uS/cm) * 0.67 = TDS ppm
Define thermal conductivity?
ability of the material to resist the temperature
Which of these has the greates effect on the electrical conductivity of solutions?
Influence on the electrical conductivity of solutions:- types of substances dissolved- concentration of solutes- temperature
