The temperature and pressure at which ice, liquid water and water vapour can exist together are

• A. 0${}^{\circ }$ C, 1atm
• B. 2${}^{\circ }$C, 4.7atm
• C. 0${}^{\circ }$C, 4.7mm
• D. 2${}^{\circ }$C, 4.7mm

Answer 1

The correct option is C 0${}^{\circ }$C, 4.7mm

All the three phases of water can coexist at 0${}^{\circ }$ C & 4.7 mm pressure.
