Thermodynamics is concerned with energy transfer between a system and its environment and with the resulting temperature variations.

Many things can happen to an object when its temperature increases.  It man get bigger or smaller, it may melt, boil, ignite, evaporate, or explode.

Temperature - We sometimes think of temperature in terms of how hot or cold the object feels.  This is not reliable.

Place a book and an aluminum pan in a freezer until they are at the same temperature.  Open the freezer and remove them at the same time.  The aluminum will feel a lot colder than the book even though they are at the exact same temperature.  The aluminum transfers heat a lot better than paper.  The heat from you hand is absorbed by the aluminum pan rather quickly so it feels real cold.
