How Insulators Affect The Temperature Of Water

A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what

Each student got a white tub and filled it up with tap water from the sink. Students were paired with two or three other people and formed their groups. Each group got 1 stopwatch, 1 thermometer, and also learned how to each other’s pulse. The temperature of the water used from the sink were adjusted beforehand to about 23°C; room temperature. Water temperature was not re-adjusted to be hotter or colder.

14. The experiment was repeated with each water temperature until all tests had been conclusively completed.

The materials we used for this experiment were two aluminum soda cans, water, ice, a graduated cylinder, a metal saucepan, a hot plate, and a

This experiment actually introduces the basic functions and the use of a hot water tank.

Problem: the temperature of water affects the amount of water droplets that can fit on the penny because of density. Density is the degree of compactness of a substance. Our phenomena is temperature. The science behind the phenomena is which temperature on a penny can hold more water. My hypothesis is that hot water can hold more water.

There will be several water baths at different temperatures in order to do the tests on at different temperatures. The water baths may not provide accurate temperature e.g. (20 ºC may be 21 ºC) so I will carry out each test at each temp on the same day to ensure a fair test. So I will be measuring the actual temperature (using a thermometer) and the precision of the thermometer is to 1d.p which is 0.5 ºC.

Our thermos was quite effective in insulating hot water, as the graph was very flat. This indicates that as time passed, the temperature of the hot water dropped very little, resembling an exponential decay graph. Trial one and trial two presented very similar results and a constant rate of change, which further reinforces the effectiveness of the thermos. The second trial basically presented identical data to the first trial, which can be seen on the graph as the two lines are merged together. The lumps in the graph for the control were resulted from the accidental moving of the temperature probe or the occasionally currents of air flowing across the cup,

Then the first flask was removed and placed on a warmer till the temperature reached 35 degrees Celsius or 95 degrees Fahrenheit. The flask was then put back into the set up with the tubes connecting the solution to the water flask. Again four trials were done in intervals of 10 minutes apart with the data recorded. Then the solution flask was

Background: By definition, an insulator is a substance that transfers heat poorly, meaning it traps the heat of what it contains. (InnovateUs). A material is either an insulator or a conductor, which is the opposite of an insulator: a material that transfers heat efficiently. What classifies these materials into these two categories are their specific heats. Specific heat is “the amount of heat per unit of mass required to raise the temperature [of a substance] by one degree Celsius,” (GSU). The higher the specific heat, the more thermal energy must be used to change the temperature. Water, for

Water is a liquid that is formed from one atom hydrogen and one atom of oxygen. Is also has a boiling and freezing point and salt and water affects both the boiling and freezing point. How exactly does salt and water affect the boiling and freezing pint of water? Which is faster in affecting water’s boiling and freezing point?. The independent variable is the amount of salt and sugar added to the water, the dependent is the freezing point and the boiling point and the control variable is the temperature of the environment which will be at room temperature and the amount of

The boiling tubes were then placed in a water bath with a fixed temperature at 40˚C.

b)A 50 g sample of water is cooled from 30 ᵒC to 15ᵒC, thereby losing

Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies, heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius, different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the internal temperature of a substance this depends on the mass and the material it’s self. To demonstrate specific heat capacity of a solid an experiment was carried out using 1kg aluminium mass and 1kg copper mass heat was conducted to the masses by
