Investigation of how Changing the Volume of Water in a Container Affects Its Rate of Heat Loss
Aim :
To investigate how changing the volume of water in a container affects
its rate of its heat loss. The variable of this investigation is the
volume of water which is put in the container.
What I already know:
I already know that the larger the volume of water there is the less
heat loss occurs. I can tell this from my previous pilot experiment
where I investigated, if the volume of water in a beaker affects its
rate of cooling.
In this experiment my conclusion was the beaker with the larger volume
has no more heat energy to give out compared to the beaker with the
smaller volume.
Prediction:
I predict that the increase of water volume in the beaker will affect
the rate of heat loss; this is because of my results of the pilot
experiment which gave me an understanding of the variable in my
Investigation.
Equipment:
This is a list of all the apparatus I will need to use to investigate
my variable.

Plan:
§ Collect Equipment needed for investigation.
§ Boil the water using the kettle.
§ Fill the beaker with the correct volume of water, then immediately
insert the thermometer into the beaker with the boiling water.
Remembering for safety reasons do not sit down while doing the
experiment.
§ Start the stop watch immediately not forgetting to record the
starting temperature. Take a reading from the thermometer every
30seconds, remembering to record results in a table.
Thermodynamics is essentially how heat energy transfers from one substance to another. In “Joe Science vs. the Water Heater,” the temperature of water in a water heater must be found without measuring the water directly from the water heater. This problem was translated to the lab by providing heated water, fish bowl thermometers, styrofoam cups, and all other instruments found in the lab. The thermometer only reaches 45 degrees celsius; therefore, thermodynamic equations need to be applied in order to find the original temperature of the hot water. We also had access to deionized water that was approximately room temperature.
Tf-Ti). Next, subtract the initial temperature, 25 degrees from the final temperature, 29 degrees putting the change in temperature at 4 °C. To calculate the heat absorbed by the water in calorimeter, use the formula (q = mCΔT). Plug in 50 mL for (m), 4.184 J for (C) and 4 °C for the initial temperature (ΔT), then multiply.
The increase in temperature will therefore increase the rate of reaction. As this is the variable I am measuring I will not keep the temperature constant and therefore I will be varying it. Volume of water- if the volume of the water is increased there is more likelihood that there will be more collisions.

A common tool that forensic units use is the ultra violet or UV light. Ultra violet light can detect different areas that contain blood that might not be able to be seen in other conditions. Another common tool is the blood reagent test that forensics use on scene. These tests determine if the blood is human or animal.

fuel, heat loss and shape of the type of wick. The type of fuel, heat loss will be the variables to change. We will measure to control the temperature of the water using a
When there is a heat exchange between two objects, the object’s temperature will change. The rate at which this change will occur happens according to Newton’s Law of heating and cooling. This law states the rate of temperature change is directly proportional between the two objects. The data in this lab will exhibit that an object will stay in a state of temperature equilibrium, unless the object comes in contact with another object of a different temperature. Newton’s Law of Heat and Cooling can be understood by using this formula:

Specific heat capacity of aqueous solution (taken as water = 4.18 J.g-1.K-1). T = Temperature change (oK). We can thus determine the enthalpy changes of reaction 1 and reaction 2 using the mean (14) of the data obtained. Reaction 1: H = 50 x 4.18 x -2.12.
After the water, has been boiling for 10 minutes, and the temperature inside the test tube has been stable for 5 minutes, record the temperature and remove the thermometer.
