Question

Which of the following are also considered to be the states of matter

Answer 1

States of matter are distinguished by changes in the properties of matter related to external factors such as pressure and temperature. States are usually distinguished by a discontinuity in one of those properties: for example, raising the temperature of ice produces a clear discontinuity at 0 °C as energy goes into phase transition, instead of temperature increase. The classical states of matter are usually summarized as: solid, liquid, gas, and plasma. In the 20th century, increased understanding of the more exotic properties of matter resulted in the identification of many additional states of matter, none of which are observed in normal conditions.
