Lab rebort Essay Example | Topics and Well Written Essays - 500 words

Lab rebort - Essay Example The mass of the substance in this experiment is water while its specific heat is the quantity of energy needed to heat one gram using a temperature of 1 degree Celsius. Through the application of this formula, the original temperature of heated water was obtained by calculating the difference in cold water temperature, hot water temperature and the final temperature. During this calculation, it was considered that the hot water temperature would be the summation of the cold and mixed water. Considering that the heat moves from the heated water to cold water, there is an equal distribution of temperature. Arguably, this method can be applicable using the first law of thermodynamics. According to this law, energy cannot be created or destroyed. Materials needed for the experiment include a coffee jar containing hot water, ice, thermometer with a capacity to measure up to 40 degrees Celsius, burets, pipets, cold water, and graduated cylinders. Other materials include styrofoam cups, balances and different metal samples. Styrofoam cup was filled with hot water (about 100 grams) obtained from the coffee pot. The exact quantity of water was determined by first finding the weight of the styrofoam cup without water, then finding its weight after adding hot water. Cold water was prepared by changing ice to tap water through heating. Its temperature was then measured. Similar quantity (100 grams) of both hot water and cold water was transferred to the styrofoam cup and stirred. After some time, the temperature of the mixture was less than 40 degrees Celsius. To obtain the quantity of cold water added, the mixture of heated water and cold water was weighed. The following equation was then used to obtain the original hot water tempe rature. To obtain the original hot water temperature, hot water temperature difference was added to the ultimate temperature of the concoction of hot and cold

Effective Leadership and Management Essay Example | Topics and Well Written Essays - 2500 words

Effective Leadership and Management - Essay Example Leadership skills direct everyone in the group towards the same direction and harness their efforts collectively. Leadership is about energizing the people towards a goal and does contribute significantly.

Leaders are seen and expected to have excellent skills for maintaining human relations. Human relation is the term that signifies how well an individual can adjust with each other while working in a group. Groups that work well together, has respect for each other and have an understanding between them surely perform better than any other group that is characterized by hostility, misunderstanding, negative feeling and lack of respect between the members (Burrow, Everard and Kleindl, 2007). Hence, it becomes necessary that the leadership skills are there in every group, which will dri ve others to achieve the goals and objectives of the organization. Thus, leadership is the key factor that leads to the success of the group. Management The term management is defined as the process of supervising and conducting a work in an efficient and effective manner to its completion through other people. In this definition, the term process refers to the primary activities of the manager. Efficiency and effectiveness deal with what the team is doing and how it could and will be done. Efficiency is about conducting the task in a correct manner and maintaining the relationship between outputs and inputs. For example, in cases where the output is more than the given effort, it referred as increased efficiency. Increase is efficiency is also signified by same output from fewer numbers of resources (Denning, 2013). Hence, good management is concerned about achieving the goal in an efficient and effective manner, thereby minimizing the cost involved in the resources. The components of management processes are planning, organizing, leading and controlling. Planning is the component that covers defining the organizational goals, creating a strategy with the aim at accomplishing these goals, developing the hierarchy plan and coordinating the whole process for achieving these goals. Organizing includes helping the individuals to identify their tasks, ascertaining how and by whom the task will be accomplished, who will be coordinating the whole activity and how the decision making will be done. Leading is the process of guiding and getting the work done. This is the process where the managers will aim at motivating the employees, direct the activities, selecting the effective communication channel and resolving the conflicts that the group members may have. The last step is controlling which is concerned with the monitoring the performance of the employees and the actual performances are compared to the set goals. On the basis of monitoring, rectifications are mad e if any deviation is found in the actual performance from the expected one (Robbins, et al., n.d.). Relationship between Leadership and Management Management and leadership cannot be separated. Regardless of locations, whether it is a school, factory, village, city, country, province or an organization, people with leadership rights are entitled to the management rights too. A leadership process certainly includes all the management proces
