HEAT AND EVAPORATION
Does more heat make water evaporate faster.
To test this I observed how the heat affected the evporation rate when water is placed under DIFFERENT WATTS LIGHT BULBS.i decided to do this expierment because I noticed how the water in my pond evaporates because of the sun every week we have to put water in the pond with our water hose.
MY HOPTHESIS WAS THAT THE 75 WATT BULB would evaporate the water faster.all substances have molecules those molecules have a certain amount of kinetic energy. That more kinetic energy molecules have the faster they move them to break free .of the bonds that hold them together. Evaporation takes place when molecules of a substance surface. Kinetic energy comes from heat the more heat the more kiiinnnetic energy iiit has and then is was makes evaporation.
1. First went out and bought my materialsb- four rubber light sockets ,nine ounce plastic cups , four 15” by 15” by 15” card board boxes, duck tape , and a dispossible camera. 2. I then put the boxes together.
3. I measured to the center of the top of the box and placed a dot there . 4. I then poked the light socket through at the dot , making sure that the prong was exactly two and one-half inches above the box. 5. I taped the light to the box in a spot.
6. I then measured to the center of the bottom the box and placed a dot there . 7. I placed a plastic cup directly on top of the dot.
8. I then taped the glass down to make sure it wouldn’t move. 9.i placed a twenty –five watt bulb in the socket and labeled the box. 10.i put the other three boxes together in the same way. Making sure that the socket was at the same height and place and the same for the cup. Except for the fact that each box had a different bulb and different label. 10.i put the other three boxes together in the same way. Making sure that the socket was at the same height and place and the same for the...
