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:
[tex]\Delta T=-4-(-18)[/tex]To solve the operations we need first change the sing inside the parenthesis since it is preceded by a minus sing.
[tex]\Delta T=-4+18[/tex]Solving the operations:
[tex]\Delta T=14[/tex]Therefore, the freezer is 14C warmer.
