Check Your Understanding

1. What is a temperature of 20 °C in Kelvin?

Answer:TK=TC+ 273 TK= 20 + 273 = 293 K

2. What is the temperature of -300 °C in Kelvin?

Answer:TK=TC+ 273 →TK=− 300 + 273 =− 27 K

This answer is impossible. 0 K is the lowest possible temperature. There can be no temperature lower than− 273 ◦C.
