  1. Day 29 Investigation 6 part 3 Condensation & Dew Point

  2. REVIEW • HOW DO YOU KNOW THAT THERE IS WATER VAPOR IN THE AIR? • WHAT DID YOU DO TO GET WATER VAPOR TO CONDENSE? • WAS HEAT TRANSFER INVOLVED IN THE CONDENSATION PROCESS?

  3. PONDER/INQUIRE • IS THERE A TEMPERATURE AT WHICH CONDENSATION STARTS TO HAPPEN? • WILL CONDENSATION TAKE PLACE AT ANY TEMPERATURE IF YOU ALLOW ENOUGH TIME FOR ENERGY TRANSFER TO OCCUR? • DISCUSS THESE 2 QUESTIONS WITH A PARTNER.

  4. PROCEDURE • FOLLOW THE INSTUCTIONS • 1. RECORD THE TEMPERATURE OF A HALF CUP OF WATER. • ADD 1 ICE CUBE. STIR CAREFULLY WITH A THERMOMETER. • MONITER THE TEMPERATURE. • IF ICE MELTS ADD ANOTHER ICE CUBE, ONE AT A TIME UNTIL YOU SEE FOG FORM ON THE SIDE OF THE CUP.

  5. PROCEDURE CONT. • REMOVE ICE CUBES THE MOMENT YOU SEE CONDENSATION ON THE CUP. • RECORD THE TEMPERATURE AT WHICH CONDENSATION FIRST OCCURRED. • POUR THE WATER INTO AN EMPTY DRY CUP. WATCH TO SEE IF CONDENSATION FORMS. IF IT DOESN’T RECORD THE TEMP.

  6. PROCEDURE CONT. • IF FOG DOES OCCUR, CONTINUE TO POUR WATER BACK AND FORTH UNTIL NO FOG FORMS ON THE CUP. • RECORD THE HIGHEST TEMPERATURE AT WHICH CONDENSATION OCCURRED. • SET UP A RECORDING CHART.

  7. CONDENSATION CHART

  8. REPORT RESULTS • WHEN FINISHED RECORDING INFORMATION ON THE CHART, WRITE YOUR GROUPS HIGHEST TEMPERATURE AT WHICH CONDENSATION FORMS. • ONCE ALL TEMPERATURES ARE RECORDED ON THE BOARD, CALCULATE THE AVERAGE TEMPERATURE AT WHICH WATER VAPOR CONDENSES. • RECORD THE TEMPERATURE ON YOUR CHART.

  9. DEW POINT • SOME PEOPLE REFER TO THE CONDENSATION ON THE SIDE OF THE GLASS AS DEW. • WHAT IS DEW? • HOW DOES DEW FORM?

  10. DEFINITION • DEW POINT - IS THE TEMPERATURE AT WHICH AIR IS SATURATED.

  11. DEW POINT QUESTIONS • OPEN TO PAGE 35 “DEW POINT QUESTIONS” IN YOUR LAB BOOK. • WORK BY YOURSELF TO ANSWER THE QUESTIONS.
