__**Conduction and Convection**__



In this simulation Gold and Hollow pipe were used to show the rate in which yellow and blue mixes and transfers heat within 49 seconds the temperatures in both flasks are balanced.

This is a graph showing the results

In this simulation Gold and Solid chunk were used. The two liquids do not mix when using the gold chunk thus rate seems to be slowed down by a vast amount.

Comparing the two graphs hollow pipe seems to be better for heat transfer as it is about three times faster than the solid chunk.

Some discoveries i made while using the other materials was that gold and copper seemed to be the fastest and both of them are alloys also can conduct electricity. Lead and stone seemed to have the same rate and the worst was glass and rubber. So it seems like that the experiment also tells about the similar properties of the materials used and how they can also be good conductors or insulators.

__**Energy Conversion in a System**__



In this simulation a cylinder is dropped to create heat. Temperature is increased by 15

In this simulation mass and height have been lowered to the least and heat only rises by .16C



In this simulation mass of the water has been lowered to the least of 0.5kg and the temperature increases greatly by the amount of 46C.

The cylinder is the energy generator, if its mass and its height were low than the least amount of energy will be generated. The Amount of energy generated also depends on the water mass because as the cylinder drops it pulls the rope causing the rotation inside the water. The more resistance that the energy of the rotation faces the less energy shall be generated. In the above there is almost little water resistance so the mass and height were at its greatest energy shall be generated the most.

__**Heat Absorption**__

In this simulation a black brick covered by glass is being shone by a flash light and in the amount of three hours the brick increases from the base temperature of 20C to 57C which is 37C increase.

Metal is shone in this simulation and in the amount of three hours time the temperature increases by 2.4C which is not a great amount compared to the black brick shone.

In this simulation a white brick is shone and increases only by 4.2C.

During the investigation i discovered that adding a glass cover would trap heat causing the amount of heat to increase greatly for some materials such as the black brick and wood but not for white brick, water, and metal. This is also very fascinating because light can enter the glass but is somehow trapped, this seems to be similar to the relationship between earths atmosphere and the sun how greenhouse effect is created by CO2 and heat is trapped but the glass just somehow traps the heat. Black brick absorbs most heat because it absorbs all colors and it turns into heat. White light consists of the entire light spectrum so thus black brick will have potential increase. But a white brick will reflect all the visible light spectrum so it will not have much of an increase. (7-8th grade science) So i think water and metal are similar to the white brick, reflecting off most of the colors.

__**Heat Transfer by Conduction**__ Aluminum is used in this first simulation to see the rate of the heat transfer from Beaker A to Beaker B.

Copper is used to transfer heat it takes half the amount that aluminum takes.

Glass takes the longest but will eventually the heat will be equaled out.

Copper, Aluminum, Steel, Glass (order of rate fastest to slowest). I noticed that glass isn't very well at transferring heat after the experiment on Conduction and Convection.
