The amount of a radioactive element remaining as a function of time. (negative exponential A(t) = A(0)*e^-kt). Similarly the amount of a chemical substance left as function of time when it reacts according to a 'first order' rate law -d[A]/dt = k[A] in many simple reactions. The amount of water left in a cylinder emptying as function of time if rate proportional to pressureThe charge left on a capacitor discharging without inductance as function of time. The density of gas under constant gravity as function of height . The rate of elementary chemical reaction as function of temperature. All negative exponentials some of them reflection fundamental physics (Maxwell distribution).

My example is in the form of a word problem about Newton's Law of Cooling.

Its an example for modeling with Exponential and Logarithmic Equations:

Use Newton's Lay of Cooling,

T = C + (T

If you do not know what the variable's mean...these are their meanings:

T = temperature of a heated object

C = constant temperature of the surrounding medium (the ambient temp)

T

k = negative constant associated with the cooling object

t = time (in minutes)
