A temperature difference of 50 K would be equivalent to a difference of 90 °F.
To calculate the delta temperature, you will take the difference between the final and initial temperature.
The delta triangle is often used as a symbol to represent change in mathematics and science. It is written as the Greek letter delta (Δ) and typically denotes a difference or a change in a variable or quantity.
Normally the term " delta T" is used to indicate the difference of two temperature readings.
Q equals delta H in a chemical reaction when the reaction is at constant pressure and the temperature remains constant.
The temperature difference between the air coming out and the air going back in.
The triangle is the Classical Greek Capital Letter ' Delta'. 'D' in modern English. 'Delta/D' means the difference in temperature. Q = m DeltaT c Energy (joule) = mass(kg) X (Difference in Temperature)T(K) X specific heat capacity. Ignoring the other terms, if the starting temperature is 273 K and the final temperature is 298K, then 'DeltaT' = ( 298-273 = 25K) Note the temperature scale is Kelvin(K) because this eliminates the use of 'Zero/ 0oC'. in the system.
Delta, is just a Greek letter very used in Math. It's meaning depends on the context. But a very common meaning, specially for capital delta ( a triangle) is difference. For instance, a temperature Delta usually means the difference of the temperatures of 2 objects. In your case, it probably means the difference of the given values
In refrigeration, delta t (ΔT) refers to the temperature difference between two points, typically the evaporator and condenser temperatures. It is an important factor in determining the efficiency and performance of a refrigeration system, with a larger delta t generally indicating better heat transfer and system effectiveness.

The magnitude of delta G is affected by the difference in free energy between the products and reactants, as well as the temperature of the system. A larger difference in free energy results in a more negative delta G, indicating a more spontaneous reaction. Conversely, a smaller difference or a higher temperature can result in a less negative or even positive delta G, indicating a less spontaneous reaction.

How heat is calculated in thermodynamics. Heat = mass x specific heat capacity x change in temperature.
