### In this question…

** If the temperature of a solution changes from 12.0°C to 29.0°C, the change in temperature (which we call delta T, or we use this symbol: ΔT) is 17.0°C. What is the ΔT in Kelvin? This is tricky and won’t be graded here, but this problem will come up a lot in chem, you MUST figure this out. If you need to, draw a diagram of 2 temperature scales next to each other.**

Many of you stopped thinking clearly. This is an important point, so follow closely.

**The temperature change from 12 to 29 centigrade is 17 degrees centigrade**.

In Kelvin, you must change the temperatures first, then do the subtraction to find out the differences.

Using K = C + 273

**12 degrees C = 285 K**

**29 degrees C = 302 K**

**302 – 285 = 17 K difference.**
