Final answer:
The claim that the highest and lowest temperatures were both recorded on the Eurasian landmass is false. The lowest temperature was recorded in Antarctica, not Eurasia.
Step-by-step explanation:
The student's question pertains to whether the all-time highest and lowest temperatures on Earth were recorded on the Eurasian landmass.
This statement is false. The all-time lowest temperature recorded on Earth's surface was not on the Eurasian landmass; it was in Antarctica. Specifically, the lowest temperature ever recorded was -128.6°F at the Vladivostok Station in Antarctica in 1983. To convert this temperature to degrees Celsius and kelvins, we use the formulas: C = (F - 32) × 5/9 and K = C + 273.15. Therefore, -128.6°F is about -89.2°C and 183.95 K.
As for possible units for density, density is a measure of mass per unit volume. Thus, three possible units for density include: kilograms per cubic meter (kg/m³), grams per cubic centimetre (g/cm³), and pounds per cubic inch (lb/in³).
