Question

What is the relative density of wood?
What is the relative density of glass?

Formula= Relative density of an object/weight of water equal to the volume of the object. ​

Answer 1

Relative density of wood

• Aim : To find the relative density of wood.
• Materials required : Overflow vessel, 50 ml measuring cylinder, spring balance, wooden block, water.
• Procedure :
• 1. Weigh the 50 ml measuring cylinder and its weight.
• 2. Weigh the wooden block and note its weight.
• 3. Pour water in the overflow vessel intil it starts dripping from its beak.
• 4. When water stops dripping from the beak, place the 50 ml measuring cylinder under it.
• 5. Slip the wooden block gently into the overflow vessel, ensuring that the water does not splash out.
• 6. Once the wooden block is in the overflow vessel, water flows out of the beak and collects in the 50 ml cylinder.
• Wait till the flow of water from beak, stops.
• 8. Weigh the cylinder with the water that overflowed and record the weight.
• `"Relative density of wood"=("Weight of the wood")/("Weight of the waterequal to volume of the wooden block")`
