a hot cup should show a typical Newton's law of cooling curve. it is very likely that the data for the cold cup does not. why might this be the case?
Homework Answers
The reason for this is because there will be some minor disturbing factors contributing in causing this variation.
When we leave the hot cup for cooling, the air flow over the cup should remain constant ideally but since the ambient conditions dont remain same so the air flow over the cup may vary either because of a use of a fan or wind blowing naturally.
Also the temperature of the ambient condition may vary due to use of different temperature controlling devices. Ac me cool the air for some time but might switch off in between during which temperature rises of the ambient air.
So if you plot the data values, and look at the graph from far away, the plot will resemble the newton's curve but on a closer look it might show some wiggles due to above reason.

Newton's Law of Cooling states that the rate of change of the temperature of a cooling body is proportional to the difference between the temperature of the body and the constant temperature of the medium surrounding the body, Apply this law to the following problem: At 10:00 am, a woman took a cup of hot instant coffee from her microwave oven and placed it on a nearby kitchen counter to cool. At this instant the temperature of the coffee was...

Introduction If a cup of cold water is mixed with a cup of hot water, the final temperature of the mixture will be between the two initial temperatures. Using information on the temperature and volume of the hot and the cold water, the final temperature of the mixture could be predicted. This virtual experiment involves mixing of equal volume of cold and hot water and prediction of the final temperature of the mixture. Procedure Step 1 To get equal volume...

Newton’s Law of Cooling says that the temperature of a hot object decreases at a rateproportional to the difference between its temperature and that of its surroundings When a person dies, the body, which is at 98.6o F, cools to a temperature of 95o F after 2 hours when the room temperature is 68o F. If a body was found in a 68o room at 4 pm and the temperature of the body (at 4pm) is 86o F, at what...

Using a graph show the Educational Investment Decision for the typical (male) high school graduate contemplating whether to invest in a college education or to enter the labor force. Your graph should clearly depict the Gross Benefits, Indirect Costs, and Direct Costs of this decision. In another graph show how this decision differs for a woman contemplating a 10-year career interruption. Discuss why women might be more likely to not make this human capital investment.
