Density of Materials - PRACTICAL Flashcards
Particle Model of Matter (12 cards)
How do you calculate the volume of a regular solid?
Use the formula for that shape
For example, the volume of a cube is equal to length x width x height.
How can you find the volume of an irregular solid?
By submerging it in a graduated container filled with water
The water displaced by the object will be transferred to the measuring cylinder.
What is the first step to find the density of a liquid?
Pour 10 ml of the liquid into the measuring cylinder and record the liquid’s mass.
What should you do after pouring the first 10 ml of liquid into the measuring cylinder?
Pour another 10 ml into the measuring cylinder, repeating the process until the cylinder is full.
What is the relationship between ml and cm³?
1 ml = 1 cm³
What do you do with the mass and volume measurements to find density?
Use the formula density = mass/volume.
What is the final step after calculating densities of a liquid?
Take an average of your calculated densities.
What is the first step to find the density of a solid object?
Use a balance to measure its mass.
How do you prepare the balance for measuring the mass of a solid?
Place the object on the balance and zero the balance.
What should you record after measuring the volume of water in the measuring cylinder?
This is the volume of the object.
Fill in the blank: The volume of a cube is equal to _______.
length x width x height.
True or False: You can find the density of a liquid by measuring its mass and volume.
True
