Match List-I with List-II and select the correct answer using the codes given below the lists:
List-I: | List-II: |
A. Boiling point of water | 233 K |
B. Normal temperature of human body | 310 K |
C. Maximum density of water | 373 K |
D. -40°F | 277 K |
Boiling point of water: The boiling point of water at standard pressure is 373 K, equivalent to 100°C or 212°F.
Normal temperature of the human body: The normal body temperature is approximately 310 K, or 37°C.
Maximum density of water: Water reaches its maximum density at 277 K, or 4°C.
-40°F: This is equivalent to 233 K or -40°C.
