Explanation / Answer

Ans 1

Incorrect scientific notation

a.

31.5 x 10-5

e.

0.000681 x 107

Ans 2

0.000681 x 107  = 6.810 x 103

Ans 3

TF = 1.8 TC + 32

Step - 1

TF - 32 = 1.8 TC

STEP 2

TC = (TF - 32)/1.8

ANS 4

P1V1/T1  = P2V2/T2

Cross multiplication method

P1V1T2 = P2V2T1

T1 = (P1V1T2)/(P2V2)
