Which sphere expands more hollow or solid?

The expansion in volume with temperature is ΔV=VγΔTorΔV∝ΔT for the given values of V and γ. so hollow sphere will expend more then solid sphere.

Which will cool faster solid sphere or hollow sphere?

Similarly, equation (3) implies that the rate of change in temperature of the hollow sphere is inversely proportional to its mass, i.e., dThdt∝1mh. Therefore, the hollow sphere cools faster than the solid sphere.

Why does a solid sphere take up more heat?

The solid sphere cools more quickly because the thermal conductivity of the solid sphere is more than that of the hollow sphere.

Is a solid and hollow conducting sphere have same radius then?

A solid sphere and a hollow sphere having same radius will hold same maximum charge.

Is volume of hollow and solid sphere same?

If the hollow one contains vacuum, then both the same. Originally Answered: You have two identical spheres. One is solid, another is hollow, both of the same volume and materials.

Will the expansion of a hollow and a solid cylinder of the same size and material be the same if they are heated to the same temperature?

If the two bodies of the same material have the same external dimensions and appearance, overall volume expansion of hollow is greater than solid body because for same volume, expansion depends on rise in temperature and the temperature of hollow body is greater due to greater mass of solid body. Both will expand same.

Which sphere will cool faster?

The cube will cool faster because it has a larger surface area.

Why does hollow sphere cools faster than solid sphere?

Actually a hollow sphere cools faster since rate of cooling is inversely proportional to mass of sphere. And mass of a solid sphere is more than that of hollow one so rate of cooling will be less than that of hollow sphere,so hollow sphere cools Faster as it’s Cooling rate is more.

What do you mean by steady state and temperature gradient in connection with heat conduction?

Steady-state conduction is the form of conduction that happens when the temperature difference(s) driving the conduction are constant, so that (after an equilibration time), the spatial distribution of temperatures (temperature field) in the conducting object does not change any further.

Can a solid conducting sphere hold more charge and hollow sphere of the same radius explain?

The whole charge of a conductor remains on the outer surface of the conductor. Hence solid conducting sphere and and a hollow sphere of same radius hold same amount of charge.

Can a solid conducting sphere hold more charge than a hollow sphere of same radius?

A solid conducting sphere holds more charge than a hollow sphere of the same radius when they are at same potential. A solid sphere and a hollow sphere having the same mass and external radius are immersed in the same liquid.

Why do two spheres of the same size expand equally?

Two spheres of the same size are made of the same material but one is hollow and the other is solid. They are heated to the same temperature, then Both spheres will expand equally. Hollow sphere will expand more than solid one. Solid sphere will expand more than hollow one.

What happens when two spheres are heated to the same temperature?

They are heated to the same temperature, then Both spheres will expand equally. Hollow sphere will expand more than solid one. Solid sphere will expand more than hollow one. Both spheres will expand equally. Both the spheres have the same volume since the radii are same.

Why does a solid sphere take longer to cool than a hollow?

The solid sphere has considerably more mass than the hollow sphere therefore has much more total heat energy. If the two spheres are otherwise identical then their surface radiation characteristics will be identical so the solid sphere will take much longer to cool.
