Transistors need thermal stabilization because the operating point of a transistor junction, similar to a diode, is affected by temperature. In fact, this can cause thermal runaway, and device destruction, if the circuit design does not compensate for this. Answer mostly correct but the operating point of a transistor must remain fixed as temperature varies whether going low or higher. that is mainly the concern about. not runaway that is caused by bad design.
Stone is most definitely not a good thermal insulator. It changes its temperature quickly with the surrounding environment. In fact, stone is a thermal conductor and will pass heat or cold right to the adjacent materials.
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
60 to 70%
In fluid coupling applications, hydraulic oils with specific viscosity ratings and properties are typically used, such as ISO VG 32, 46, or 68. These oils are chosen for their ability to provide effective power transmission, lubrication, and heat dissipation. Additionally, the oil should have good anti-wear properties and thermal stability to ensure reliable performance. Always refer to the manufacturer's specifications for the recommended oil type for a specific fluid coupling system.
Yes, fabric can be a good thermal insulator. Natural fibers such as wool, cotton, and silk are known for their insulating properties due to their ability to trap air. Additionally, specialized synthetic fabrics like fleece and thermal materials are designed to provide excellent thermal insulation.

It depends on the shape of the object and how its mass is distrubuted
Good thermal insulators have high thermal resistance and low thermal conductivity, which helps to slow down heat transfer. Materials like foam, fiberglass, and wool are good insulators. Good thermal conductors, on the other hand, have high thermal conductivity and allow heat to transfer quickly. Copper, aluminum, and silver are examples of good thermal conductors.
No, acrylic is not a good thermal insulator. It has low thermal resistance and can allow heat to transfer easily.
Acrylic is not a good electrical insulator because it is a conductor of electricity. However, it can be a good thermal insulator as it has low thermal conductivity.
No. They should be good thermal insulators.
No, krypton is not a good thermal conductor. It is a noble gas and has very low thermal conductivity compared to other materials.
Yes, that is what "good thermal conductor" means.
Napkins are not good insulators, as they are thin and do not provide much thermal or electrical resistance. They are more commonly used for wiping and cleaning purposes.
No, potassium is not a good thermal conductor compared to other materials. It has a relatively low thermal conductivity, meaning it is not efficient at transferring heat.
Dividends are good for investors because they provide a steady stream of income, offer a way to share in a company's profits, and can indicate financial stability and growth potential.
