1. a)
So you could just change the equation around.
You could add 273.15 to both sides, and get
c + 273.15 = K
You could subtract K from both sides
C - K = -273.15
And so on.
1 b)
So since you know the variable C, you can just put that in the equation.
23 = K - 273. 15
I would add 273.15 to both sides.
23 + 273.15 = K
296.15 = K
So therefore the temperature in Kelvins would be 296.15
1 c) So here it would be easier to just convert 300 Kelvins to Celsius.
Put in all the variables first.
C = 300 - 273.15
And then just subtract.
C = 26.85
26.85 > 25
So therefore 300 Kelvins is greater.
