During boiling, the temperature ofa (2)changes at the start then it becomes (3) Answer: Substances can change phase—often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous.

WebPhase changes can have a tremendous stabilizing effect even on temperatures that are not near the melting and boiling points, because evaporation and condensation (conversion of a gas into a liquid state) occur even at temperatures below the boiling point. WebBoiling is the process by which, the liquid phase of a substance is converted into its gaseous phase. This process occurs with the increase in temperature to the boiling temperature or with the decrease in pressure …

WebFig. 10 shows the temperature change of the core-catcher part that changes with time. Because the heat flux is set higher toward the exit as can be seen in Fig. 5, the temperature of core-catcher increases. The temperature of core-catcher continued to increase until 480 s. Web19 feb. 2024 · Why does the temperature remain constant during a change in the state of matter? It doesn't exactly, as we see below, but it almost does under typical conditions where something called heterogeneous nucleation (that is, easy formation of molecular-scale clusters of the new phase) dominates.
