Answer with Explanations:
1. Describe the type of heat transfer that occurs between the hot water and the spoons?
Heat transfer refers to the transfer or movement of heat from one object to another object. It is always transferred from the object with the higher temperature to the object with the lower temperature.
The heat transfer between the hot water and the spoons is made possible through "conduction." Conduction (thermal conduction) happens when two objects of varying temperatures come in contact with each other.
2. Describe what will happen to the temperature of the spoons after they have been on water for a couple of minutes.
The temperature of the spoons will get higher than their normal temperature. As the objects are placed in the hot water, the molecules in them moves fast resulting to a high temperature. This makes the spoons warmer. The transfer of heat will depend on whether the spoons are good conductors. Good conductors of heat allows more heat transfer while poor conductors of heat allows less heat transfer. In the image above, the wood's temperature did not increase because it is resistant to temperature change through "thermal expansion." This allows the wood to expand when heated.
3. Classify each materials being tested as a conductor or an insulator.
Conductors, particularly "heat conductors" allow heat to transfer through them, while insulators inhibits heat from flowing through them. They are totally opposite. In the image above, the conductors are: silver and stainless steel; the insulators are: plastic and wood.
4. Describe how radiation could affect the system.
Radiation happens when the energy coming from the heated objects are emitted outwards in the form of waves (electromagnetic waves). In this case, if the bowl of water will be placed over a burning coal of fire or a stove, then the fire in the stove will emit heat through radiation. You will feel it if you move closer to the boiling pot or bowl. This could make the temperature in the surrounding environment higher.
