For most chemical elements or compounds, freezing and melting occur at the same temperature. For pure water at 1 atmosphere pressure, this temperature is 32°F (0°C). Increased pressure has a very slight effect in lowering the freezing/melting point of water.

This may be illustrated by a block of ice, upon which a heavy weight is resting. The increased pressure under the weight causes the ice to melt and flow off to the side, where it freezes again.

water will freeze at 32 degrees pressure or no pressure

there is a pressure-temperature relationship, so the temperature freezing point depends on the pressure.
