Why the outer body of inner bottle of thermos flask is made silver in colour?
The outer body of the inner bottle of a thermos flask is often made silver in color to provide a reflective surface. This reflective surface helps to minimize heat transfer through radiation, improving the overall insulation of the flask and allowing it to better retain the temperature of the contents inside.
Why glass breaks due to temperature change?
Glass isn't really a solid - it's a 'super-cooled liquid' - sudden temperature change causes 'thermal shock' where the outer surface expands or contracts quicker than the rest of the glass - causing it to break.
What does silver layer of an insulated bottle this do to radiated heat?
The silver layer of an insulated bottle reflects radiated heat, helping to maintain the temperature of the contents inside by reducing heat transfer between the inner and outer layers of the bottle. This helps to keep hot beverages hot and cold beverages cold for longer periods of time.
What is the charge per unit length on the inner surface and on the outer surface of the outer cylinder when finding the charge distribution in a system?
When determining the charge distribution in a system with cylinders, the charge per unit length on the inner surface of the outer cylinder is equal to the negative of the charge per unit length on the outer surface of the inner cylinder.
How thermos bottle reduces loss and gain of heat?
A thermos bottle reduces heat loss and gain through a vacuum layer between its inner and outer walls, which minimizes conduction and convection. The shiny surface inside the thermos reflects heat radiation back into the bottle, preventing heat transfer. The tight seal of the bottle also helps to prevent air exchange, further reducing heat transfer.
Why droplets of water appears on the outer surface of the cool water bottle?
It's called condensation. The temperature difference between the bottle and the surrounding air - causes water to condense out onto the bottle's surface.
Why water droplets could not form on the outer surface of the bottle?
The water is too hot
How is warmer blood cooled?
The blood carries the heat from the warm interior of the body to the surface, where it is cooled off in the skin. After cooling, the blood is carried back to the interior of the body. In this way the blood equalizes the body temperature, and keeps it from becoming too hot in some parts and not warm enough in others.
How hot is the outer of the Sun?
The surface temperature of the Sun is around 5800 K
Is the outer core as hot as the surface of the sun?
Its quit tricky. Answer is yes. Its because of the electro magnetic radiations of sun that causes high temperature at surface. So surface temperature is nearly same to core temperature

What changes do you observe on the outer surface of the glass when we keep ice cubes in it?
Condensation occurs on the outer surface of the glass when you keep ice cubes in the glass at room temperature or hotter.
How hot is the outer mantel?
The outer mantle of the earth ranges in temperature from around 600 to 900 degrees Celsius. This layer is composed of solid rock that is constantly being heated and cooled by the layers above and below it.
How hot is the outer crust?
Check your thermometer. That's how hot it is on the outer crust where you are. There exists a geothermal gradient where temperature rises with depth from the surface. See the link below.
What happens to a hot bimetallic strip when it is cooled to room temperature?
It Melts:P.
What happened when the outer surface of the moon cooled to form a crust over the molten interior?
When the outer surface of the Moon cooled, it solidified to form a crust over the molten interior, leading to the formation of the Moon's solid landscape. This cooling process caused the surface to contract, creating features like cracks and ridges. Additionally, volcanic activity occurred in some regions, resulting in the formation of lunar maria—dark basaltic plains. Over time, impacts from asteroids and comets further shaped the Moon's surface, creating craters and other geological features.
What is the covering of the outer surface of bone?
The outer surface of the bone is called the periosteum.
