Food Fuel Lab Report : Food Burning Lab

For the Mole lab, my team claimed there was 1,992 beans in the large display jar. The estimate was close but still off by 59 beans. The actual amount of beans in the jar was 2,051. To figure out our estimate we used a beaker of beans to experiment with. We first found the tare weight of the beaker, which was 49.912, and the weight of the beaker with the beans, 95.301. Our next step was the weight ten beans of different sizes and find the average of the beans. We found the average weight of the beans to be .47g. After doing this we then subtracted the weight of beaker with the beans from the tare weight to find the weight of the beans. We found the weight of the beans to be 45.389g. After finding the weight of the beans we dived that by he average weight of our ten beans and got 97 beans in our beaker. When we counted our beans in our beaker, we found it to be 105. We then repeated this test but using the tare

Energy is the strength and ability that is required in order to perform physical or mental activities. There are different forms of energy these consist of: magnetic, kinetic, heat, light, gravitational, chemical, sound, electrical, elastic and nuclear.

I watt-I joule/sec. most useful kinds of energy=chemical and potential. One calor is the enrgy it takes to raise one kg of water by one degree Celsius. 4k joules=calories. Solar cells- crystals that convert sunlight directly into electricity. K energy depends on sq of v. double speed=kinetic energy increased by factor of 4.. temp is a measure of hidden kinetic energy.

Energy is a concept.� Most definitions of the word energy fail to provide its exact meaning when applied to scientific matters.� In science the word energy is a concept that expresses two measurable properties, heat and work.� Here is the relationship of energy, heat and work:

INTRODUCTION Energy is the ability to do work. It can transform into different types of energy such as potential and Kinetic. Potential and Kinetic energy are two opposite types of energy. Potential is energy of position-when an item is unmoving it has the potential to move. Kinetic energy is energy of motion-as the item is in motion it is converted to kinetic.

There are two types of energy: kinetic energy and potential energy. Kinetic energy is energy possessed due to motion, and potential motion is energy which

The objective is to determine the presence of a cation and anion by a chemical reaction through determining the presence of the cations and anions in an unknown salt.

Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes. Another key measurement of this lab was to teach the

Prior to conducting the experiment, the members of the group planned how the practical would be conducted, what variables they were going to measure, and delegated roles evenly between the members. For example, one member was assigned the roles of diluting the Catalase concentration, whilst the other member was responsible for measuring out 50ml of hydrogen peroxide (H2O2). Communication was also vital to ensure that the students knew exactly how the experiment would be conducted. Furthermore, the ideas of each member in the group were valued and taken into consideration with regards to how the investigation should be conducted. As the practical was conducted in a tight space, the students were required to communicate effectively with others to prevent any collision. In addition, cooperation was compulsory, as students were required to share the materials and equipment. All these skills were vital in order for the experiment to be conducted efficiently and coherently within the time

The materials used for the experiment were 800 ml glass jars, two pieces of cotton string that both measured 6.5 inches long, granulated white sugar, 4 cups of water, two wooden chop sticks, parchment paper, two small same size, shape, and type metal screws, tablespoon measuring spoon, permanent marker, ruler, tape, pot, stove,

What is energy? Energy is the ability to do work, it is the “power that comes from the use of physical or chemical resources.” In your home energy can come in many forms such as heat, light, and even electricity. The problem is some of us, meaning people, in general, know little to anything about the word energy itself. When we think about energy, we think about the energy it takes to get up in the morning. Sometimes as students we do not notice how much, and when we use energy. We use energy in everyday life, and it is very important to understand that.

When conducting the experiment the results for each alcohol were where they were anticipated to be supporting the

Normally, based on their level of understanding, students will choose to either work as a group or complete the assignment individually. After the students complete their lab report, we discuss the activity, analyzing the process and answering any questions.

Purpose: This lab taught procedures for determining heat of capacity of a calorimeter and measuring enthalpy of change for three reactions. It also enforced methods of analyzing data obtained through experimentation and calculating enthalpy. These procedures are used in the branch of thermodynamics known as thermochemistry which is the study of energy changes that accompany chemical reactions. Concepts from this lab can be used to determine the potential energy of a chemical reaction. Much of the energy people depend on comes from chemical reactions. For example, energy can be obtained by burning fuel, metabolizing of food or discharging a batter.

There are no definite forms of energy since possibilities of new forms of energy are limitless. However, the various forms of energy in physical science include thermal, chemical, electric, radiant, nuclear, magnetic, elastic, sound, mechanical, and luminous energies (Foland 13). Thermal energy or heat is the energy in random motion of particles. Chemical energy refers to the energy from the aggregate of positioning of electrons and protons. Radiant energy is the energy of electromagnetic radiation while nuclear energy and electric potential energy is energy emanating from nuclear fission and electrical processes respectively. Sound is a form of mechanical vibration, which propagates through any mechanical medium. It is closely related to the ability of the human ear to perceive noise.
