Question

Statements : Water boils at 100${}^{\circ }$C.
Water freezes at 0${}^{\circ }$C.
Conclusions : At low pressure, water boils at lower temperatures.
The conclusion drawn is :

• A. Definitely true
• B. Definitely false
• C. Either probably true or probably false
• D. Data inadequate

Answer 1

Answer: (D)

Data inadequate

Given statements that water boils at 100 degree and freeze at 0 degree doesn't comment anything on pressure dependence of boiling and freezing points .
Hence the given conclusion is not satisfied by any of them.
