anonymous one year ago Absolute zero is A. –273.15°C. B. the lowest possible temperature. C. the temperature at which the average kinetic energy of particles would theoretically be zero. D. all of the above

C. Temperature at which the average kinetic energy of the particles would be theoretically zero is correct. because temperature is defined as the average kinetic energy $KE = \frac{ 1 }{ 2 }mV ^{2}$ B. this is theoretically the lowest possible temperature. this is also correct. A this is true because Kelvin = C+273 so the absolute zero is 0K or -273C
