Although it is the second planet from the sun, Venus is the hottest planet in the solar system. The reason Venus is hotter than even Mercury is not because of its position in the solar system but because of its thick, dense cloud layer. The lower left of this image shows a differential...
But the real vanguard in solar science might be one of the satellites itself. SolO's orbital radius drops to 0.284 astronomical units (AU), only about sixty solar radii, bringing it within the orbital perihelion of Mercury. One of its chief scientific objectives is investigating theconnection be...
because it is room-temperature superconductivity at such a high temperature (approximately 127 degrees Celsius). The changes that room-temperature superconductivity will bring to people's lives will be earth-shattering. By then, we can ride on floating superconductive cars when we...
Because the top of the tube is open, the water can evaporate and pick up dust and debris. Sealing mercury in a small glass thermometer solves these problems. The small size of the bulb means that the bulb reaches the temperature of what it is measuring very quickly, and the tu...
It hasn't changed much since Thomas Edison introduced it in 1879. It still generates light by heating a tungsten filament until it reaches 4,172 degrees Fahrenheit (2,300 degrees Celsius) and glows white-hot. Unfortunately, all of that white light is not very green. Only 10 percent of ...
So for a fuel injected engine, we use sensors to determine the pressure in the intake manifold and the air temperature. However, the temperature in this equation is “absolute temperature†measured in Kelvins which is equal to degrees Celsius + 273°....
27/19= the temperature and dewpoint. In this case the temperature is 27 degrees Celsius and the dewpoint is 19 degrees Celsius. A3001= the atmospheric pressure, a.k.a. altimeter setting. In the US this is expressed in Hg, so this would correspond to 30.01 inches of mercury (the A si...
Heat is a form of energy. It cannot be seen, but the flow of the heat can be perceived if there is some change in temperature. If the heat is supplied to a substance, its temperature increases, and on the removal of the heat from the substance, the temperatu...
As the second planet from the Sun, Venus is one of the brightest orbs you can see from our world and the closest planet in our solar system to Earth. While itsmass and size make it Earth's twin, Venus differs in the number of moons it has — zero. That's right. Like Mercury, th...
as it is called-was denser in the center than it was in its outer reaches. It was also hotter in the center-perhaps as hot as 1,200 degrees Celsius, in the region where Earth now finds itself. And because the central part of the disk was hotter, it was also rockier. Only rocky ...
