In summary, "heat transferred" refers to the thermal energy transferred from one object to another, causing an increase in temperature. The amount of heat transferred to an aluminum flagpole is important as it can affect its structural integrity. This can be influenced by factors such as temperature difference, material, and duration of heat exposure. It can be measured using a thermometer or calculated using specific heat capacity. To prevent damage, precautions such as monitoring temperature and limiting heat exposure can be taken, as well as using high-quality, heat-resistant aluminum.

Homework Statement



An 8 000-kg aluminum flagpole 100-m long is heated by the sun from a temperature of 10°C to 20°C. Find the heat transferred (in J) to the aluminum if the specific heat of aluminum is 0.215 cal/g °C.

Homework Equations



Q=mc delta T

The Attempt at a Solution



(8000000g)(.215cal/g)(10)

so i get 17200000 cal convert to J
7.2e7 J

is that correct??

1. What is meant by "heat transferred" to an aluminum flagpole?

"Heat transferred" refers to the amount of thermal energy that is transferred from one object to another due to a temperature difference. In this case, it refers to the amount of heat that is transferred to an aluminum flagpole, causing its temperature to increase.

2. Why is the heat transferred to the aluminum flagpole important?

The heat transferred to the aluminum flagpole is important because it can affect the structural integrity and stability of the flagpole. Excessive heat can cause the metal to expand and weaken, potentially leading to damage or collapse.

3. What factors affect the amount of heat transferred to the aluminum flagpole?

The amount of heat transferred to the aluminum flagpole can be affected by several factors, including the temperature difference between the flagpole and its surroundings, the material and thickness of the flagpole, and the duration of the heat exposure.

4. How is the heat transferred to the aluminum flagpole measured?

The heat transferred to the aluminum flagpole can be measured using a thermometer to monitor the temperature change of the flagpole. It can also be calculated using the specific heat capacity of aluminum and the amount of heat energy applied to the flagpole.

5. What precautions should be taken to prevent damage from heat transferred to the aluminum flagpole?

To prevent damage from heat transferred to the aluminum flagpole, it is important to monitor the temperature of the flagpole and limit the amount of heat exposure. If possible, shade or cool the flagpole during hot weather to minimize heat transfer. Additionally, ensuring the flagpole is made of high-quality, heat-resistant aluminum can help prevent damage.
