You can quickly estimate Fahrenheit temperatures from Celsius by doubling the Celsius temperature and adding 30. This will give you an approximate Fahrenheit equivalent. For example, if it's 20°C, double it to get 40, then add 30 to get 70°F.
Celsius is the international and metric scale for temperature, as opposed to the English unit scale of Fahrenheit. It is named for Anders Celsius (1701-1744), a Swedish astronomer and scientist who developed the early form of the scale.
One way to quickly convert Celsius to Fahrenheit in your head is to double the Celsius temperature and add 30. For example, to convert 20 degrees Celsius to Fahrenheit, double 20 to get 40, then add 30 to get 70 degrees Fahrenheit. This method provides a fairly accurate estimation for everyday use.
Liquid nitrogen can evaporate because its boiling point is very low at -196 degrees Celsius. When exposed to higher temperatures, it can quickly vaporize into nitrogen gas.
Mount Tambora's lava can reach temperatures of around 1,300 to 1,600 degrees Celsius (2,372 to 2,912 degrees Fahrenheit). This extreme heat allows the lava to flow relatively quickly and efficiently when erupting from the volcano.
Instant cold packs typically reach temperatures around 32-41 degrees Fahrenheit (0-5 degrees Celsius) when activated. This temperature drop occurs quickly due to a chemical reaction that absorbs heat from the surroundings, making the pack feel cold to the touch.
