Investigating the Relationship Between Heat Loss and Surface Area

Investigating the relationship between heat loss and surface area:volume

Introduction

I am investigating the relationship between heat loss and surface area:volume. To do this, I will perform an experiment where I will fill 3 different sized beakers with hot water, record the heat loss and look at the similarities and differences between the data I will record.

Prediction

I think that in doing this experiment I will find that the smallest beaker cools more quickly than the other 2. I can back this up with evidence such as; a baby is smaller than an adult, and loses heat more quickly than an adult. This is because of the surface area:volume of the baby is higher than the adult's. The adult holds more volume than the baby, but has less surface area in comparison to the baby. This means that the baby will lose heat more quickly than the adult will.

Equipment list

* 3 different sized beakers (600ml, 250ml and 100ml)

* 3 thermometers

* stopwatch

* hot water bath

Diagram

Method

I will take 3 different sized beakers (600ml, 250ml & 100ml) and measure the volume and surface area. I will do this by measuring the depth and diameter of a beaker and use this equation (?xr²xdepth) to find the volume, and this equation (2?r² + 2?rxdepth) To find out the surface area. (Then I will divide the volume by the surface area to find out the Surface area: volume)
