What is the absolute zero on the Celsius scale according to the material?

Explanation:
Absolute zero is the lowest possible temperature, where molecular motion effectively stops. The Kelvin scale defines zero at this point, and Celsius and Kelvin are linked by the relation K = C + 273.15. So when C = -273.15, K = 0, which is absolute zero. Therefore, the absolute zero on the Celsius scale is -273.15 °C. The other values are just higher temperatures on the Celsius scale and do not represent the zero of the Kelvin scale.
