(F-32)/9 = t/5

so F = 9t/5 + 32

on taking t = 0 we will get F = 32

thats why it makes an intercept of 32 in y axis

Two absolute scales A and B have triple points of water defined to be 200 A and 350 B. What is the relation between Ta and Tb?

(1) Ta = Tb/2

(2) Ta = 7Tb/4

(3) Ta = 2Tb

(4) Ta = 4Tb/7

273.15 K = 200 A

and 273.15 K = 350 B

so A = 273.15 K/200 and B = 273.15 K/350

so Ta A = TbB

or Ta/T= B/A = 200/350 = 4/7 

so 4th option

The absolute zero temperature is

(1) -273° C

(2) -273.15 K

(3) -273.15° F

(4) -273.15° C
