Correct option is D
The correct answer is (d) –273° Celsius.
Lowest Possible Temperature:
- The lowest possible temperature is –273.15°C, known as absolute zero.
- At this temperature, the kinetic energy of particles in a substance theoretically reaches its minimum, and no further heat energy can be extracted.
Significance of Absolute Zero:
- Absolute zero is the starting point of the Kelvin scale (0 Kelvin = –273.15°C).
- It represents the theoretical point where molecular motion stops, though it is impossible to achieve in practice.
Additional Information:
- Temperature: A physical quantity that measures the degree of hotness or coolness of a body.
- Temperature is measured in Celsius (°C), Fahrenheit (°F), and Kelvin (K).
