On a chilly 10°C day, your friend who loves cold weather says she wishes it were twice as cold. Taking this literally, show that the temperature she wishes for would be ?131.5°C.

ANSWER: 0 The temperature was 10 C . The conversion to absolute scale kelvin is, 10 C = 273 + 10 = 283 K . [As 0 C = 273 K ] She wants twice cold which means the temperature should be half. Mathematically the temperature she wants is, 283 K / 2 = 141.5 K . Again if we convert it to celsius scale, 0 K = 273 C , we know. [absolute zero] 0 0 0 141.5 K = 273 C + 141.5 C = 131.5 C . CONCLUSION: So, technically when she says that she wants double the cold of 10 C , it is 131.5 C . This is the temperature she wants.
