To calculate delta T:
\[ \Delta T = T2 - T1 \]
Where:
Delta T, denoted \(\Delta T\), is the term and symbol used to describe the change in temperature of a substance, system, or object. The delta in delta T is the term used to describe the change, and the T denotes temperature.
Let's assume the following values:
Using the formula:
\[ \Delta T = 30 - 20 = 10 \]
The change in temperature (Delta T) is 10°C.
