Newton's Law of Cooling

Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle dQ = -h(T-Ta)dt = mcdT}

Q is thermal energy

h is the heat transfer coefficient

T is the temperature of the water

Ta is the temperature of the air (environment)

t is time

m is mass of water

c is specific heat capacity of water

The heat transfer coefficient h is depended on the material. Alpha is dependent on the surface area and beta is dependent on

/alpha = h/a

-h/mc dt = dT/(T-Ta)

-ht/mc + C = ln(T(t)-Ta))

-e^(ht/mc) + C = T(t)-Ta

-Ce^(ht) + Ta = T(t)
