| The soft metal gallium has such a low melting point that it will liquefy on contact with your hand. |
| The drainage water, saturated with iron hydroxides and humic acids, corrodes even a stainless steel and liquefy the belly. |
| Heating and cooling the mould in order to liquefy the plastic required that the mould be rapidly cycled through a wide range of temperatures. |
| Another solution could be to liquefy the gas and pump it through existing oil pipelines. |
| Exporters liquefy the gas and ship it in tankers, then convert it back to gas at U.S. ports and deliver it through pipelines. |
| Dewar used liquid air to pre-cool compressed hydrogen, reducing its temperature enough to liquefy the gas by expansion. |
