Answer:

1. The elevator goes 11 floors down..which means that it is 20-11=9th floor. Then it goes 5 floors up..which means 9+5=14th floor. Therefore..the elevator is on the 14th floor.

2. A change of one degree Celsius = a change of one Kelvin, but a Celsius temperature is never equal to a Kelvin temperature. There are no negative temperatures in the Kelvin scale. To convert a Kelvin temperature to Celsius, subtract 273.15.
