If the state variables change, such that a different configuration is more favorable, the substance will perform a phase transition. This phase diagram (from Wikipedia's Phase Diagram page), shows this quite well. Using the dashed green line instead of the solid green line we have the phase … scalextric ford rs200Witrynasubstance because the composition of liquid air is different from its gas phase. Phases of a pure substance Pure substances may exist in more than one phase, but the chemical composition is the same in all phases. Pure substances may exist as a solid, liquid, and a gas. Solids are considered to have the strongest molecular bond. saxton the avenue

WitrynaIt is a solution because the mixture created has only one phase. Through combining two or more chemical substances, mixtures are formed. If the material has more than one phase, it is otherwise referred to as a mixture. What is a simple mixture? A mixture is a material composed of two or more simpler substances in chemistry. WitrynaSomething that contains only one chemical substance. For example table salt, which is primarily composed of NaCl, is typically an impure substance. The reason is that while the vast majority of the salt is composed of NaCl typically there are trace …

WitrynaA heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions.
