-459.67°F (-273.15°C)
The lowest possible temperature, or absolute zero as it is called, is -459.67°F (-273.15°C). It is also called 0 kelvin, a scale with increments equivalent to degrees of Celsius, but which uses absolute zero rather than water's freezing point as its starting point. This is the point at which all atomic motion ceases. Absolute zero, 0 K, which is equivalent to –273º C, is the lowest theoretical temperature a material can have. Other than the placement of the zero point, the Kelvin and Celsius scales are the same, so water freezes at 273 K and boils at 373 K. Best Answer: The lowest POSSIBLE temperature is absolute zero, which defines 0 degrees Kelvin (-273.15 degrees C. or -459.67 degrees F.) If by 'nature' you mean ANYWHERE outside a laboratory, intergalactic space would probably offer the lowest temperatures in the known Universe. It is 0 degrees Kelvin, and is calculated the be the lowest temperature that matter can be. Since at this temperature, all motion in matter stops, including all atomic vibrati … ons. Since there is no energy state that is lower than no kinetic energy, this point is called absolute zero. Report Abuse. Lowest theoretical temperature is 'absolute zero' or 0 Kelvin, which equates to -273.15 degrees Celcius (or just -273 C). This is the temperature at which there would be an absence of thermal energy/absence of atomic motion. Source(s): Used to teach science. Report Abuse. The lowest theoretical temperature would be answer b. Using different temperature scales ie Celsius, Kelvin and Fahrenheit, we can figure out which is the lowest. It is a fact that 0 K is the absolute lowest possible temperature to obtain at that temperature everything stops, electrons stop moving.
