Question

your freezer should be kept at -18 C. One day you woke up and noticed the door was left open and the temperature is now -4 degrees C. How many degrees warmer is the freezer now?

Answer 1

where are given that the reference temperature of a freezer is -18 C, if the temperature is -4 C. the difference in temperature will give us how many degrees warmer the freezer is:

`\Delta T=-4-(-18)`

To solve the operations we need first change the sing inside the parenthesis since it is preceded by a minus sing.

`\Delta T=-4+18`

Solving the operations:

`\Delta T=14`

Therefore, the freezer is 14C warmer.
