Final answer:
The lowest natural temperature on Earth of -128.6°F (-89.2°C) was recorded in Vostok, Antarctica. That temperature is equivalent to 183 K when expressed in kelvins. Density can be measured in units such as kg/m³, g/cm³, and lb/ft³.
Step-by-step explanation:
The lowest natural temperature on Earth was recorded in Antarctica. Specifically, the temperature of -128.6°F was measured in Vostok, Antarctica, in 1983. To convert this temperature into degrees Celsius, we subtract 32 from the Fahrenheit temperature, multiply by 5, and then divide by 9. The calculation is as follows: (-128.6 - 32) × 5/9 = -89.2°C. To convert the temperature into kelvins, we add 273.15 to the degree Celsius temperature, which gives us 183.95 K. However, since temperature in kelvins is usually reported to the nearest whole number, we would simply say that the temperature is 183 K.
When discussing density, we can measure it in multiple units, such as kilograms per cubic meter (kg/m³), grams per cubic centimeter (g/cm³), or pounds per cubic foot (lb/ft³), among others.
