I need an introduction to Enhancing indoor air quality and safe entertainment in sports halls (report) And talking about the elements using It is used to improve the air inside the sports hall, improve the audience stands, and improve the sound of music using sound insulation of (Sensor, funs, section equipment, Acoustic to prevent sound echo in halls, O2 ventilator) with an explanation of the function of each element using formula heating exchange for (sensor, funs, section equipment, Acoustic to prevent sound echo in halls, O2 ventilator) and the physical rules for each element, and in the end I want a conclusion pls very urgent

Suggested Development to Solar System:

i need heat transfer by natural convection experiment   please i want new not old thanks

(Thermodynamics) Plz solve the question and show the steps

Why is information regarding the specific volume of gases important to the designer of air-conditioning, heating, and refrigeration equipment?

https://pubmed.ncbi.nlm.nih.gov/32521345/ In the literature review, they should present the system installed and the main results obtained. In other words, the enhancement due to the installed system. They have to define the system used in this study. (the report talking about ventilation) pls in briefly Don’t using chatgpt please urgent i will give u like
