WebA physical change is a change in the state or properties of matter without any accompanying change in its chemical composition (the identities of the substances contained in the matter). We observe a physical change when wax melts, when sugar dissolves in coffee, and when steam condenses into liquid water (Figure 1.4. 1 ). WebJun 1, 2024 · Steam is often used for process heating. Primarily, steam transfers heat when it condenses. To transfer heat at high temperature, the steam pressure must be very high. For example, 600-psig steam condenses at approximately 490°F, but many processes require heating to higher temperatures than that.
