PLS ASAP Why must the metal be shiny for my dew point project? this is it... 1. Record the temperature of the air. 2. Fill a shiny metal can with water at room temperature. 3. Slowly add ice to the water and stir gently with a stirring rod or spoon handle while keeping the bulb of the thermometer surrounded by the ice-water mixture. Be careful to not tap the thermometer with the stirring rod. Continue to add ice until a film of water appears on the surface of the metal can. 4. Record the temperature of the water in the can as soon as the moisture appears. This temperature is the dew point. 5. Repeat this experiment at least 2 more times to confirm the data.
