freez·ing point (frē′zĭng) The temperature at which a liquid becomes a solid. For a given substance, the freezing point of its liquid form is the same as the melting point of its solid form. The freezing point of water is 32°F (0°C); that of liquid nitrogen is -345.75°F ...

Unlike conventional antifreezes, such as the ethylene glycol commonly used in cars, the proteins create a phenomenon called thermal hysteresis: They lower the freezing point of water below 0 [degrees] C without changing the temperature at which ice melts as it is heated. Freeze! Insect proteins...

For mixtures of compounds (as petroleum), there are ranges of melting and freezing points versus percent of the mixture melted or frozen. For a mixture, the initial melting point is close to the melting point of the lightest compound in the mixture, while the initial freezing point is close...
high-quality antifreeze boiling point usually above 106 ℃. Force the use of ethylene glycol antifreeze systems quality formulations to meet the requirements of different freezing and boiling points. If you do not use antifreeze or the use of low-grad 不冻液有高沸腾点,沸点水通常是100 ℃,优质不...
