The density of hematite ore is <u>4.78 g/cm³</u>.
Let the mass of the ore be m₁ , the volume of the flask <em>V</em>, total mass of water and ore M, mass of water be m₂, density of ore ρ₁ and the density of water be ρ₂.
Density of a substance is defined as the mass per unit volume.
The mass of water in the flask is given by,
Calculate the volume V₂ of the water in the flask.
Calculate the volume V₁occupied by the ore in the flask.
1 ml is equivalent to 1 cm³.
Calculate the density of the ore.
The density of the hematite ore is found to be 4.78 g/.cm³
Answer: radiator - A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting - Ice melts because heat moves to the ice from the air.
Explanation:
This is because the pressure is so much larger at 3000 meters than it is at sea level. Hope this helps.
