its a movement of small particles of matter
When matter is heated, its particles gain energy and move more rapidly, leading to an increase in temperature and expansion of the material. Conversely, when matter is cooled, its particles lose energy and move more slowly, causing a decrease in temperature and contraction of the material.
Sort of. In the temperature range of 0-4 Degrees Celsius water contracts when heated and expands when cooled. Outside of this temperature range it behaves normally.
Examples of expansions of matter include the increase in volume of a gas when heated and the expansion of a metal strip in response to temperature changes. Examples of contractions of matter include the shrinking of a balloon when the gas inside cools down and the contraction of a metal wire when it is cooled.
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
Atoms themselves are not easily destroyed when matter is cooled or heated. However, extreme conditions, such as in a nuclear reaction or high-energy collision, can break apart the nucleus of an atom. In everyday temperature changes, atoms remain intact but may change their arrangement within a substance.
what changes take place when water is heated or cooled
what changes take place when water is heated or cooled
When heated it get larger and when you freeze it the matter gets smaller with an exeption to ice
When matter is heated, its particles gain energy and move more rapidly, leading to an increase in temperature and expansion of the material. Conversely, when matter is cooled, its particles lose energy and move more slowly, causing a decrease in temperature and contraction of the material.
density changes when the substance changes.
Sort of. In the temperature range of 0-4 Degrees Celsius water contracts when heated and expands when cooled. Outside of this temperature range it behaves normally.
A solid can change Into a liquid when it is heated Example- when heated solid chocolate, the chocolate changes into a liquid. A liquid Can change into a solid when it is cooled Example - If you leave juice in the freezer , the liquid changes into a solid.
when zinc carbonate is heated it' white colour changes to yellow . And when it is cooled it again changes to it original colour
Examples of expansions of matter include the increase in volume of a gas when heated and the expansion of a metal strip in response to temperature changes. Examples of contractions of matter include the shrinking of a balloon when the gas inside cools down and the contraction of a metal wire when it is cooled.
Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.
Water changes from one state to another by being heated or cooled
The opposite of heated is cooled.
