Question

What is `k` in Newton's Law of Cooling?

Answer 1

Newton's Law of cooling has the following formula:
`T (t) = T_e + (T_0 − T_e )*e^ (- kt)`

where T`(t)` is the temperature of the object at time t, `T_e` is the constant temperature of the environment,`T_0` is the initial temperature of the object, and `k` is a constant that depends on the material properties of the object.

So, `k` is a constant in relation to the same type of object. If we change the object and its material properties, the constant `k` will have a different value (for instance, silver will have a different `k` from wood).
