How Much Of An Orange Is Water

How much water is in an orange??

Problem:

What percent of an orangish is h2o?

Enquiry:

All living things such equally humans and plants must have water to survive. H2o gets recycled in a process called the water cycle. Evaporation is the change of liquid-water to water vapor. Evaporation of h2o occurs everyday whether information technology is in a cup or outside in a lake. Evaporation is a major part of the h2o cycle.

Dry out Foods
A major section of food manufacture today is production of dry-foods. It is a great way to preserve food when not in demand. All sorts of foods are dried including meats, vegetables, fruits and instant coffee products. Drying food is the process of evaporating all the interior h2o of a food production and in most cases this will exist done in a hot air tunnel. Many seasonal products will be dried to reduce the cost of storage and distribution of the products during the twelvemonth. Drying Foods is less costly to store over a long flow of fourth dimension. Some liquid foods such every bit orange juice are unremarkably partially dried to lose 80% of their water and the outcome is called concentrate.

Hypothesis:

Since there is a lot of liquid juice in an orangish, our hypothesis states that there will be 50% or more than h2o in an orangish.

Cloth needed for this experiment:

1. An orange
2. Kitchen knife
3. Paper plate
4. Aluminum foil
5. Weighing Scale

Procedure:

Weigh the orange
Weigh the newspaper and aluminum foil which is being used to dry the orangish in.
Cut the orange in very sparse slices to speed up the drying procedure.
Spread the slices over the paper, which is placed on the aluminum foil.
Go along it in a warm place until it is fully dry. Y'all can expect it to take 4-36 hours depending on the heat and airflow. Nosotros used a desk low-cal with a 150 watt lamp and a fan as a drier. We mounted our desk-bound lite to be about a foot above the sliced oranges and place the fan about ten feet away from the orange slices facing the oranges to create airflow. In this way nosotros completed the drying process in x hours.
Weigh the orangish slices once fully dried. Don't forget to deduct the weight of the newspaper and the aluminum foil if you are weighing the orange slices with the newspaper and aluminum foil.

Record And Analyze Data:

After the orange slices where completely dry, we put them dorsum on the weighing scale and weighed information technology with the newspaper and aluminum foil. Nosotros then subtracted 15 grams from that total since the foil and paper weighed 15 grams. But similar we stated before, the orange weighed 309 grams earlier the experiment was started and at present weigh 58 grams. To effigy out the percentage of solids in the orange, we divide the weight of dry sample to the weight of original sample that is : (58/309=0.1877). To figure out the percentage of h2o in the orange, nosotros used this formula: (309-58)/309=0.8122
In effect of our experiment, we constitute out that orange is consisted of 81% water.
