The air would still be too thin to breathe. The lack of atmosphere would chill the Earth’s surface. Plants and […]

What was the first microchip used for?
What was the first microchip used for? Texas Instruments first used the chips in Air Force computers and the Minuteman Missile in 1962. They later used the chips to produce the first electronic portable calculators. The original IC had only one transistor, three resistors, and one capacitor and was the size of an adult’s pinkie […]

What happens to gas temperature when compressed?
What happens to gas temperature when compressed? I know from Charles’ law that under constant pressure, the volume of a gas is directly proportional to its absolute temperature i.e. Thus accordingly, during compression, temperature of the gas would decrease. This means that when we compress a gas slowly, the temperature of the gas increases. Does […]
