MCQ

The warming or cooling rate of a drink is proportional to the difference between the ambient temperature TaT_a and the current temperature T{T} of the drink. Which equation describes this relationship?

Select all that apply :

dTdt=k(Ta−T)\frac{d T}{d t}=k(T_{a}-T)

dTdt=kTa−T\frac{d T}{d t}=\frac{k}{T_{a}-T}

T(t)=kTa−T,T(t)=\frac{k}{T_{a}-T,}

T(t)=k(Ta−T)T(t)=k(T_{a}-T)
