Sense: noun/1

All three words involve lowering temperature, but they differ in purpose and range. Cooling is the broadest term — you can cool a drink, a room, or a machine, with or without a specific preservation goal. Chilling is less formal and usually means making something cold enough to be refreshing or to stop it from spoiling over a short period, such as chilling wine before serving. Freezing goes further by bringing the temperature below 0°C, turning water into ice, which preserves food much longer than refrigeration does. In practical use: 'I put the leftovers in the fridge for refrigeration' means keeping them cold for a day or two; 'I put the meat in the freezer for freezing' means keeping it solid-ice for months.

Etymology

LatinFrenchEnglish

The word comes from the Latin verb 'refrigerare', meaning 'to make cool or cold'. This is formed from the prefix 're-' (used here for emphasis) and 'frigus', meaning 'cold' or 'frost'. The term entered English through French in the late 1500s and was first used for cooling drinks. By the 1800s, with the invention of ice-making machines, it took on its modern meaning of preserving food by mechanical cooling.
