The formula for the rate of cooling under natural convection is given by:
q = h * A * ΔT
Where: q = rate of cooling (W) h = convective heat transfer coefficient (W/m^2*K) A = surface area of the object (m^2) ΔT = temperature difference between the object and the surrounding fluid (K)

Formula for the Rate of Cooling Under Natural Convection:
``` Q = hA(T_s - T_∞) ```
where:
- Q is the rate of cooling (heat transfer rate), in Watts (W) - h is the convective heat transfer coefficient, in Watts per square meter per Kelvin (W/(m²K)) - A is the surface area of the object, in square meters (m²) - T_s is the surface temperature of the object, in Kelvin (K) - T_∞ is the ambient temperature, in Kelvin (K)
Symbol Definitions:
- Q: The rate at which heat is transferred from the object to the surrounding air. - h: A measure of the efficiency of the convection process. It depends on the properties of the fluid (air in this case), the flow conditions, and the geometry of the object. - A: The surface area through which heat is transferred. - T_s: The temperature of the object's surface. - T_∞: The temperature of the air surrounding the object.
