relationship between mass‚ volume‚ and density of matter. 3. Use the particle theory to explain the differences between solids‚ liquids‚ and gases. 4. Comment on the accuracy of the statement below. Describe some exceptions to the statement if there are any. In general‚ solids are denser than liquids‚ and liquids are denser than gases. 5. Use the particle theory to explain why changing the temperature of a fluid can also change its density. 6. The density of a fluid usually decreases as the temperature

ABSTRACT The densities of several liquid and solid samples were determined as an exercise in measurement. Density‚ being an inherent and intensive property of a substance‚ was also used to determine the identity of an unknown liquid sample. Proper procedures on measurement were observed in order to determine the mass‚ volume‚ and density of the samples. Four liquid samples were used namely water‚ isopropyl alcohol‚ coconut oil‚ and an unknown liquid sample. The experimental density values were measured

buoyancy? – Buoyancy is the upward force caused by a fluid such as water. • What is Archimedes Principle? – The buoyant force is equal to the weight of the displaced water. • What is density? – Density is the mass of a material per unit volume. – Example: The density of steel is 10 times more than the density of wood. Hypothesis I think when the weight of the object is greater than the displaced water‚ it will sink. If the weight of the object is equal to the weight of the displaced water
