The liquid state is colder and denser but the molecules are still the same. Water is another example. The compound water is made up of two hydrogen (H) atoms and one oxygen (O) atom...

That is one of their physical characteristics. They also can be compressed easily.

Solution-type of mixture formed when I substance dissolves in another Energy-The ?colder' the phase, tends to have less energy Freezing Point-Temperature where liquid turns to solid Atomic Number-Number of protons in the nucleus of an atom Matter-Has mass and takes up space 4 phases of matter-solid, liquid, gas, plasma Mixture-Matter that consists of 2 or more substances mixed together but NOT chemically combined ex: salt, sugar Atom-Smallest particle of an element that has the properties of a element How do we measure mass-In grams Mass number-Sum of protons and neutrons in its nucleus Element-A substance that has only 1 kind of atom Chemical Symbol-short way of representing elements Melting Point-temputure where solid changes to a liquid Freezing-change from liquid to solid Condensation-change from gas to liquid (when drops get on glass) Protons and Electrons-are equal to each other Vaporization-change from liquid to gas How do you change phases of matter-add or take away energy SCIENCE Solution-type of mixture formed when I substance dissolves in another Energy-The ?colder' the phase, tends to have less energy Freezing Point-Temperature where liquid turns to solid Atomic Number-Number of protons in the nucleus of an atom Matter-Has mass and takes up space 4 phases of matter-solid, liquid, gas, plasma Mixture-Matter that consists of 2 or more substances mixed together but NOT chemically combined ex: salt, sugar Atom-Smallest particle of an element that has the properties of a element How do we measure mass-In grams Mass number-Sum of protons and neutrons in its nucleus Element-A substance that has only 1 kind of atom Chemical Symbol-short way of representing elements Melting Point-temputure where solid changes to a liquid Freezing-change from liquid to solid Condensation-change from gas to liquid (when drops get on glass) Protons and Electrons-are equal to each other Vaporization-change from liquid to gas How do you change phases of matter-add or take away energy SCIENCE Solution-type of mixture formed when I substance dissolves in another Energy-The ?colder' the phase, tends to have less energy Freezing Point-Temperature where liquid turns to solid Atomic Number-Number of protons in the nucleus of an atom Matter-Has mass and takes up space 4 phases of matter-solid, liquid, gas, plasma Mixture-Matter that consists of 2 or more substances mixed together but NOT chemically combined ex: salt, sugar Atom-Smallest particle of an element that has the properties of a element How do we measure mass-In grams Mass number-Sum of protons and neutrons in its nucleus Element-A substance that has only 1 kind of atom Chemical Symbol-short way of representing elements Melting Point-temputure where solid changes to a liquid Freezing-change from liquid to solid Condensation-change from gas to liquid (when drops get on glass) Protons and Electrons-are equal to each other Vaporization-change from liquid to gas How do you change phases of matter-add or take away energy SCIENCE Solution-type of mixture formed when I substance dissolves in another Energy-The ?colder' the phase, tends to have less energy Freezing Point-Temperature where liquid turns to solid Atomic Number-Number of protons in the nucleus of an atom Matter-Has mass and takes up space 4 phases of matter-solid, liquid, gas, plasma Mixture-Matter that consists of 2 or more substances mixed together but NOT chemically combined ex: salt, sugar Atom-Smallest particle of an element that has the properties of a element How do we measure mass-In grams Mass number-Sum of protons and neutrons in its nucleus Element-A substance that has only 1 kind of atom Chemical Symbol-short way of representing elements Melting Point-temputure where solid changes to a liquid Freezing-change from liquid to solid Condensation-change from gas to liquid (when drops get on glass) Protons and Electrons-are equal to each other Vaporization-change from liquid to gas How do you change phases of matter-add or take away energy
