The simplest formula for calculating Delta T is:

Delta T = Final Temperature - Initial Temperature

For more detailed thermodynamic calculations:

Delta T = (Heat Energy Transferred) / (Mass × Specific Heat Capacity)

Où :

• Température finale (T₂) = Temperature at the end of the process.
• Température initiale (T₁) = Temperature at the beginning of the process.
• Heat Energy Transferred (Q) = The amount of heat added or removed (measured in Joules or Calories).
• Masse (m) = The mass of the substance (measured in kilograms or grams).
• Capacité thermique spécifique (C) = The heat required to raise the temperature of one unit mass by one degree (measured in J/kg·K or cal/g·°C).

This equation helps scientists and engineers accurately measure temperature variations in physical and chemical processes.

Exemple

Scenario: Heating Water for a Chemical Experiment

A scientist heats 500g d'eau de 25 ° C à 80 ° C and wants to calculate the Delta T.

Step 1: Apply the Simple Formula

Delta T = Final Temperature - Initial Temperature
Delta T = 80 - 25 = 55 ° C

Step 2: Apply the Heat Transfer Formula

If Q = 115,500J, the specific heat capacity of water is 4.18 J/g·°C, and mass is 500g:

Delta T = Q / (m × C)
Delta T = 115,500 / (500 × 4.18) = 55 ° C

Interprétation:

Le Delta T of 55°C indique un significant temperature rise, confirming the correct amount of heat energy was applied.
