A certain property eta varies according ...

A certain property `eta` varies according to the law `eta=(alpha(t-t_(0)))/(1+alphat)` where `alpha` is a constant and `t_(0)` is a temperature less than `t`. If `etagt1` is unthinkable what is the absolute zero on this property? What is the relation of `t` and `T` on this property?

Text Solution

Verified by Experts

The correct Answer is:
`T=T+1/(alpha)`
