Aim: Perform an experiment to determine the latent heat of fusion for milk. Materials: Calorimeter Celsius Thermometer Platform balance Kettle Milk ice cubes Stopwatch Hot Water Procedure: The copper cup was weighed and its mass was then recorded. The kettle was then used to boil water and this water was poured into the copper cup. The mass of the cup plus the hot water was calculated and recorded. The copper cup was then placed in the insulated container. The water’s temperature was

CRITICALLY EVALUATE THE FACTORS INFLUENCING THE GLOBAL HEAT BUDGET - 40 MARKS The global heat budget is the balance between incoming insolation‚ and outgoing radiation from Earth. There are many factors that influence this heat budget‚ some of which are more important than others. In this essay I am going to describe and explain each factor involved. Insolation is the incoming energy from the sun in shortwave ultraviolet (UV) radiation. The distribution of insolation over the Earth’s surface

In the 1995 Chicago Heat Wave‚ mortality was related to living alone in that living along doubled a person’s chance of not surviving the heat wave. On the other had‚ and form of social connection lessened the chance of dying. Some of the main reasons that this relationship exists are because most of the people living along were older people and increasingly people with poor mobility were living alone. Living alone as an aging person was thought to be the ideal way for them to live because it gave

Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different

It is clear that there were many failures and opportunities to correct and prevent this incident from occurring. As they performed their investigation‚ they were able to identify several direct‚ contributing‚ and root causes‚ although they don’t specifically designate
