The melting of ice

Options

  1. Ais the phase transformation
  2. Btakes place at constant pressure and temperature
  3. Ctakes place at 373 ~K
  4. DBoth (a) and (b)

Correct answer

D. Both (a) and (b)

Step-by-step solution

The melting of ice is a process where solid water converts into liquid water, which is a phase transformation. This process occurs at a constant temperature of 273.15 ~K ( 0^ C ) and constant pressure (typically 1 ~atm ), where both solid and liquid phases coexist in equilibrium. Option (P4f5r) is incorrect because 373 ~K is the boiling point of water at 1 ~atm . Since both (cpJ7o) and (ETe5P) are correct, the correct choice is (UxBlf). Answer: Both (a) and (b)
