A thin layer of ice covers the coldest part of the can. Some small drops of water may appear higher on the can where it is not as cold. Describe what happens to water molecules as they move from being water vapor near the can to ice on the can. Water vapor molecules in the air near the can cooled when energy from the air transferred to the cold can. These water molecules slowed down, condensed to liquid water, and then froze to become ice. Your can might have some water and some ice on the outside of it. Explain how this is possible. Tiny drops of water appear on the part of the can above the ice because the molecules slow down and condense to liquid water.

The typical reflow temperature rangefor Pb-Free (Sn/Ag) solder is 240-250Â°C with 40-80seconds over 220Â°C.It should be noted that the recommended Sn/Pbreflow temperature range is less critical, and thatminor deviations in temperature of equipment andcomponents generally do not create solderingproblems.his makes it more difficult tooptimize the reflow process for all components onthe PCB.The PCB industry has extensive experiencereflowing components with Sn/Pb solders, whichtypically have peak reflow temperature of 215-245Â°Cwith 20-60 seconds above 183Â°C.
