Question

When one mole of ice is converted to water at0°C and 1 atm, the work done (L atm) isA 1.1 x 10-4B. 2.0 x 10-3C. 2.0 x 10-4 D. 1.1 x 10-5​

Answer 1

The square root of 2, or the (1/2)th power of 2, written in mathematics as √2 or 21⁄2, is the positive algebraic number that, when multiplied by itself, equals the number 2. Technically, it is called the principal square root of 2, to distinguish it from the negative number with the same property.

As a good rational approximation for the square root of two, with a reasonably small denominator, the fraction 99/70 (≈ 1.4142857) is same.
