Solution

On heating the copper washer
(a). Its internal diameter will increase as the copper washer expands outwards
(b). Volume will increase as the size of the metal expands on heating
(c). Mass will remain the same as the mass does not change with change in temperature
(d). Density will decrease as the volume of the washer increases on heating and density is inversely proportional to volume
(e). External diameter will increase because the copper washer expands outwards

Concept: Temperature
