3D printers need 50 watts to 1900 watts, generally depend on its size to work between 30° to 300°C. 3D printer can use electricity for operating as per the requirement of manufacturing design, complex shape, the material being used for casting, filament energy consumption to heat the material, threshold temperature for filament and print bed, etc. It also depends upon the type of methods used to heat filaments, material for fusing like Stereolithographic (SLA), Fused Deposition Modeling (FDM), Digital Light Process (DLP), EBM, MJF, etc. 3D printing is the process of manufacturing 3-D solid objects from digital files using a
Enhancing the flavor of beer and the ability to drink more beer are the two prominent reasons why people put salt in their beer. There are several other reasons also to add salt in beer such as no frequent peeing, a family tradition, peer pressure, someone cool is doing it, and many more. Note that the excessive consumption of beer can led to the condition of beer potomania. Have you ever seen your friends adding salt to beer? Well many people add salt to beer for different reasons such as salt enhances the flavor of the beer, helps them
Clouds can go up to 60,000 feet (18288 m) high in the sky. These high-level clouds include cirrus, cirrocumulus, and cirrostratus that formed in the altitude range of 16,500 feet to 60,000 feet. The height of a cloud depends on various factors such as moisture content, ambient temperature and pressure, updraft winds, and dust particles in the atmosphere. As these factors vary with different locations, clouds are formed at different altitudes at different locations.
A typical cloud is made up of water droplets and ice crystals. This cloud composition usually varies with altitude and ambient conditions such as temperature and pressure. The high-level clouds such as cirrus, cirrostratus, and cirrocumulus are mostly made of ice crystals while low-level clouds such as cumulus, stratus are composed of water droplets. However, note that the low-level clouds can also be made up of water droplets and ice crystals if the ambient temperature drops below the frost point.
A typical cumulus cloud having a volume of 1 km3 can weigh approximately 3.3 million pounds (1525 tons). The weight of the clouds depends on the cloud liquid water content value and other factors such as temperature and pressure. Clouds at higher altitudes such as cirrus clouds have a lower mass than that of cumulonimbus clouds.
Clouds can float because clouds are made up of tiny micron size water droplets that can float similar to dust particles in the air. Due to tiny size, the water droplets and ice crystals have low terminal velocity and hence, they fall very slowly. The continuous warm updrafts in the atmosphere also force clouds upwards and keep them floating.
Clouds look white because the water droplets present in the clouds scatter visible light into all wavelengths equally. Due to identical scattering of all wavelengths, the sunlight remains white and clouds appear white.
Clouds are formed when the water vapors present in the air condenses and turn into water drops or ice crystals. The condensation of water vapors occurs on the tiny dust particles at an altitude where the temperature matches the dew point of the water.
High-level clouds such as cirrus clouds can move at a speed of more than 100 mph and can travel more than 2400 miles in a day. Clouds move due to wind and how fast a cloud can move is determined by the altitude at which they are formed. The wind speed increases with an increase in altitude. Therefore, high altitude clouds such as cirrus clouds move faster compared to low altitude clouds such as cumulus clouds.
Carbon has 4 valence electrons in the outermost shell. Carbon has atomic number 6 which belongs to group 14 in the periodic table. A carbon atom has a total of 6 electrons revolving around the nucleus. The innermost shell of the carbon is fully occupied with 2 electrons in the 1s orbital while the next shell which is also the outermost shell gets partially filled with the remaining 4 electrons. These four electrons are the valence electrons of the carbon that are present in the 2s and 2p orbitals of the outermost shell. What are valence electrons in Carbon?
