9. In an experiment, the luminous flow from a bulb H was recorded as a function of the bulb temperature T. Results are presented in the table. emperature T. Resueresented inthe table T, K9 9501150 135015501750 1950 2150 2350 2550 2750 H.Lm | 0.96 | 2.7 | 6.0 | 13 | 24 | 42 | 67 | 196 | 161 | 238

Solution

When we graph and check we find that the two are exponentially related.

Hence we take ln Hlm = y and ln Tk =x

Prepare table as follows:

Hence we have ln H.lm = -35.447+5.169ln TK

Or H.lm = e^-35.447(TK)^5.169

H.lm = 4.047 (TK)^5.169x 10^-16
