Can a Hollow Metallic Ball Withstand the Heat of the Sun's Radius?

In summary, to prevent a metallic ball from becoming hot due to the sun's rays, one can either provide shade or make the surface shinier. This is because a shiny surface reflects the sun's rays, preventing them from being absorbed and increasing the temperature. Additionally, if the ball is not hollow, it would be harder to heat up due to the high heat conduction of metals. However, having a very large solid metal sphere would be excessive and heavy.

The sun makes it hot. Temperature of the surroundings will stem from wind and other factors but the ball is more affected by the sun rays. shade it.

Or shine it. The shinier it is, the cooler it will be.

Good answer but can you explained this? How the shiness prevent the ball to gets hot? Thank you

A shiny surface reflects away the Sun's rays that would otherwise be absorbed and increase temperature.

Thank you very much for the help.

Is it hollow?
 
  • #8
no. it is a very big sferical.

I agree with lots o watts. metals tend to have high heat conduction. He is saying that if it is not hollow, then it would be much harder to heat it up. I can almost guarantee you it is hollow. It also seems excessive to have a very large sphere of metal. it would be very heavy.
 

FAQ: Can a Hollow Metallic Ball Withstand the Heat of the Sun's Radius?

What is metallic ball heat transfer?

Metallic ball heat transfer is the process by which heat is transferred from one object to another through contact with a metallic ball. The metallic ball serves as a medium for the conduction of heat between the two objects.

How does metallic ball heat transfer work?

When a metallic ball is in contact with two objects at different temperatures, heat will flow from the object with higher temperature to the object with lower temperature. This is due to the difference in temperature causing a transfer of energy from the hotter object to the cooler object.

What are the factors that affect metallic ball heat transfer?

The factors that affect metallic ball heat transfer include the material of the ball, the temperature difference between the two objects, the surface area of contact, and the distance between the two objects.

How is the rate of metallic ball heat transfer calculated?

The rate of metallic ball heat transfer can be calculated using the equation Q = kA(T1-T2)/d, where Q is the heat transferred, k is the thermal conductivity of the metallic ball, A is the surface area of contact, T1 and T2 are the temperatures of the two objects, and d is the distance between the two objects.

What are the applications of metallic ball heat transfer?

Metallic ball heat transfer has various applications in industries such as manufacturing, energy production, and electronics. It is also used in household appliances such as refrigerators and air conditioners to transfer heat from inside to outside. Additionally, it is used in scientific experiments and research to study heat transfer and thermodynamics.
