If a sample of water is heated from 20°C to 80°C, what is the temperature change ΔT?

The change in temperature is the difference between the final and initial temperatures. Here, the water goes from 20°C to 80°C, so the increase is 80°C − 20°C = 60°C. Therefore, ΔT = +60°C. A positive ΔT means the temperature rises by 60 degrees.
