# Investigate whether the huddling behaviour of the emperor penguins helps to conserve heat?

Extracts from this document...

Introduction

Leanne Jones R11 Task: Investigate in to whether the huddling behaviour of the emperor penguins helps to conserve heat? Introduction/ background I am going to investigate if penguins huddling together help them keep the body temperature up. As the emperor penguins have small feet, wings, head and a relatively small surface area great for conserving heat, they also have a thick layer of fat underneath their skin for insulation also their feather helps to insulate, they are also are warm blooded. All these are great for the cold conditions that are in the Antarctic. Penguins have to survive extreme conditions the temperature in the Antarctica; the temperature has been down to -88.3 �C, but is normally below are round about -40. The wind has also been as fast as 200 mph. When a penguin breed it goes about 180 mile in to the Antarctica ice where there is less precipitation and the weather condition are less extreme. So with all the ways in which the penguins are adapted to live in the weather condition it. They still go to some where with less extreme conditions as the males will spend a lot of time standing in a huddle.[LJJ1] The heat will be transferred by radiation; Radiation is electromagnetic energy given off by all objects, which are above the temperature of 0 �C. ...read more.

I think this is because I could only measure as accurate to a half a degree. And also I have averaged all the results so that could be why the results are the same twice is three times. There are also some results that are out from the line of best fit. This could be for the same reason as before. The averages are strange of one of the results from the first results are out. On my graph I have also circled some results that are odd (have drop temperature a lot) this could be fore the same reason as before or I could be because I have read the thermometer wrong. All my result could be a bit out as I took the temperature off all the test tubes so I had to average all of those out and then average the results again because I repeated all the experiment 3 times. From my graph all of the lines of best fit are curved and the gradient at the top is greater than the gradient at the bottom; so the temperature went down slower the cooler the water was. ...read more.

1. ## Why do penguins huddle to keep warm?

submerge the test tube arrangement into it until they are all fill. I shall do this as it will assure that all the test tubes start off at 70 degrees unlike if I were to pour water into each individual test tube.

2. ## To investigate the heat evolved, temperature rise, and heat of neutralization that takes place ...

After finishing finding the heat evolved from each volume I decided to calculate the rise of temperature for each volume by the formulae Q=mc?? Q = Heat Evolved. M = for the mass or the volume used. C = is the specific heat of capacity of water which is the same for the acid and the alkali (4.2 KJ)

1. ## Specific Heat Capacity

I will use the same balance to measure the masses so that any differences due to measurement are the same for all the metals. 2. Volume The volume of each mass is used in the density calculations and so must be regulated to allow me to draw reliable conclusions.

2. ## Why Penguins Huddle.

two graphs one for the inner test tube and one for the outer test tube. This will enable me to compare the two temperatures. Test2: this test will be set up in much the same way as test one but there will be a third ring of test tubes.
