Q1:

Water content of a soil sample is the difference of the weight of the given sample at the given temperature and the weight determined after drying it for 24 hours at temperature ranging from

A 80° to 90°C

B 90° to 95°C

C 95° to 100°C

D 103° to 105°C

E 105° to 110°C

ANS:E - 105° to 110°C

Organic soil = 60°.
Gypsum = 80°. It's actually not less than '105°.

105 is in 2options, D & E. But D has a limit less than 105, so E is the correct answer
