Question: Expansion Two spheres are made of the same meta and have the same radius but one is hollow and the other is solid at room temperature The temperature of both spheres is increased by the same amount Which sphere expands more? Solid sphere +△a Hollow sphere 1+△ They expand by the same amount +△b all dimensions increase The increase is proportional to original size of that dimension For the sphere the releval dimension is its outer radius Reeder-05-06 Physics 201: Lecture 22, Pg 16Reeder - 05-06 Physics 201: Lecture 22, Pg 16 Question: Expansion Two spheres are made of the same metal and have the same radius, but one is hollow and the other is solid at room temperature.
