Question

Absolute zero is A. the temperature at which the motion of particles theoretically ceases. B. defined as 0°C. C. the triple point for water. D. all of the above

Answer 1

Absolute zero is the temperature at which the motion of particles that constitute heat will be minimal. The answer is A. It is the lowest temperature that is theoretically possible. It is zero on the kelvin scale, but equivalent to -273.15°C. Hope i helped.

Answer 2

The correct answer is A. The temperature at which the motion of particles theoretically ceases.

Step-by-step explanation:

The term "absolute zero" is used to refer to a temperature (degree of heat) in which particles have no movement or only minimal vibration as in this temperature the energy of particles is affected. Due to this, the absolute zero is one of the lowest temperatures that exists as it is equivalent to -273 °C or -459 °F, although it has been proved temperature can be even lower at certain circumstances. According to this, "absolute zero" is mainly defined by the lack of motion in particles and thus, the correct answer is "he temperature at which the motion of particles theoretically ceases".
