Answer
An increase in $1^{\circ}C$ is an increase in $1~K$, so temperature differences, temperature increases, and temperature decreases will have the same value when expressed in kelvins or Celsius degrees.
Work Step by Step
When we are dealing with temperature differences, as well as increases and decreases in temperature, then kelvins or Celsius degrees can be used interchangeably.
