Please answer me fast fast A platinum resistance temperature detector (RTD) is used to measured temperature of the hot gas.

The temperature coefficient of platinum is 0.0039 C^-1.
We have an RTD (Resistance temperature detector ) which is used to measure temperature of hot gas having,
Resistance of sensing element (R2) = 250.3 Ω at temperature (T2) of hot gas
Resistance (R0) = 80 Ω at 0 C
Resistance (R1) = 120 Ω at 100 C
Temperature co-efficient () = 0.0039 C-1
We have been asked to find the temperature of the hot gas (T2) .
Now temperature resistance relationship of metals are given as,
R1 = R0 (1 + T1)
R2 = R0 (1 + T2)
we can also write this equation is simplified form as,
T2 - T1 =
where,
T2 will be temperature of the gas.
