How come VCAA uses degrees and Kelvins interchangeably? Like in 2008 mcq 14, they said the specific heat capacity of water is 4.18J/ml/K then the answer is in J/degree celcius?

essentially, 1C=274K. an increase in 1C = increase in 1K. it doesnt really matter.

Basically you are using in the E=mcT formula. As others have mentioned Celsius and Kelvin share the same scale so it doesn't matter. But you should convert to Kelvins to ensure consistency.
