if it a 2D shape it would be a circle,but if it is a 3D shape it would be a sphere
* a acorn is solida acorn is solid a acorn is solid
A circle is a plane figure. A 'circular' solid figure would be a sphere.
You would have to put mercury in very low temperatures until it was a solid.
The property of the object would change "solid, liquid, or gas"
density
That object would have to be a solid using the lengthxwidthxheight.
The volume of a solid object is measured using a mathematical equation appropriate to its geometry, provided it is of regularly geometrical form (polyhedral or circle-based). Alternatively, if it is irregular but small and can be immersed, by displacement of water.
No. A circle is a 2-dimensional object a sphere is 3-d. However, a circle would generate a sphere if rotated about a diameter.
A force that could cause a object to move in a circle would be centripetal force. That is a product of mass and centripetal acceleration. It is quite a bit complicated.
For an object that is already a solid the change in its temperature does not affect its weight by any noticeable amount. The only change would result from the volume decrease as the object contracts when cooled. By occupying less space, it would displace less air and that would decrease the buoyancy of the object. That, though, would cause the object to weigh (slightly) more.
You can deduce that, if the object was in the form of of a solid "blob" it would not float on water.
