A metallic ball and highly stretched spring are made of the same material and have the same mass. They are heated so that they melt. The latent heat required

A metallic ball and highly retched spring are made of the same material and have the same mass. They are heated so that they melt the latent heat required

Two wires of the same material and same mass are stretched by the same force. Their lengths are in the ratio

A sphere, a cube and circular plate of same material and same mass are heated to same temperature. Then cooling of

A sphere, a cube and a thin circular plate, all made of the same material and having the same mass, are initially heated to a temperature of 200^@C . When left in air at room temperature, the following cools fastest

A solid sphere, a cube and a plate, all are made of same material and all have same mass. These are heated to a temperature 100^@C and then allowed to cool at the temperature of room. Which of these will cool down first –

Two substance of same size are made of same material but one is hollow and the other is solid. They are heated to same temperature, then
