Final answer:
To find the coldest day we need specific temperature data, which isn't provided. The coldest recorded temperature of -128.6°F converts to about -89.2°C or 184 K. Units for density include g/cm³, kg/m³, and lb/ft³.
Step-by-step explanation:
To determine the coldest day, we would need the specific temperatures from Monday to Friday. However, the question provided does not include this necessary data. Instead, it provides unrelated information. To convert Fahrenheit to Celsius, we would use the formula ℃ = 5/9(℉ - 32). Using this formula, the temperature of -128.6℉ would be approximately -89.2℃. To convert Celsius to Kelvin, the formula is K = ℃ + 273.15. So, converting -89.2℃, we get approximately 184 K. Additionally, some possible units for measuring density include grams per cubic centimeter (g/cm3), kilograms per cubic meter (kg/m3), and pounds per cubic foot (lb/ft3).
