Question

We aim to hold graduation meetings with your families in the A21 classroom where we process the Pre-Pandemia Heat Transfer course. About 100 people attended the ceremony in the classroom measuring 15m x 20m x 10 m and the internal ambient temperature is 20°C due to the working air conditioning device. Let's face it, the air conditioning device malfunctions and each person in the living room gives an average temperature of 350 kJ per hour. Find the classroom temperature at the end of 30 minutes, acknowledging that the living room walls did not receive heat or pass and that the air conditioning was not working for 30 minutes.
