What is the density of a plastic block with a mass of 2.0 grams and a volume of 2.5cm3?
What is the density of a plastic block with a mass of 2.0 grams and a volume of 2.5cm3?
How could you predicd if a block of plastic will float in water?
The block of plastic must be less dense than the water in which it will be placed in order to float. Density is equal to mass over volume (D=m/v), so you could calculate the density of the block of plastic and of a sample of the water by dividing the weight of each sample by the respective volume of each sample. If the density of the plastic is less than the density of the water, it floats! A hint: the maximum density of fresh water occurs at 4 C∘and is equal to 1 gram per 1 milliliter. When a solute - such as salt - is added, the density of water will decrease.
which has the greater mass a large block of plastic or a small block of the same plastic?
Mass depends on how much of something there is, as well as how dense it is, AKA volume and density. Assuming these two blocks have the same density since they’re the same plastic, the bigger block would have more mass.
A block of plastic is released under water will it sink or come up to the surface of water?
The density of water is greater than that of plastic. When a block of plastic is under water, the magnitude of the buoyant force or upthrust exerted by water on the block is greater than the magnitude of the weight of the block. Hence, the block of plastic released under water will come up to the surface of water.
What has the greater density a cube of water measuring 1cmX1cmX1cm and having the mass of 1g or a block of plastic measuring 2cmX3cmX1cm with a mass of 4g?
The cube of water would have a greater density because it has a mass of 1g in a smaller volume of 1 cm³, resulting in a density of 1 g/cm³. The block of plastic has a mass of 4g in a larger volume of 6 cm³, resulting in a density of 0.67 g/cm³.
What has the greater density a cube of water measuring 1cmX1cmX1cm and having a mass of 1g or a block of plasting measuring 2cmX3cmX1cm with the mass of 4g?
Density = mass/volumeFor the cube of water having a mass of 1g:Volume of a cube of water measuring 1cm X 1cm X 1cm =1cm3.Density = 1g/1cm3 = 1g/cm3For the block of "plasting" having a mass of 4g:Volume of the block of plasting measuring 2cm X 3cm X 1cm = 6cm3.Density = 4g/6cm3 = 0.7g/cm3I will let you decide which has the greatest density.
What is the density of Plastic bottles?
plastic water bottle density
What has greater mass a large block of plastic or a small block of the same size block plastic?
large block
What is white plastic?
White plastic is plastic that is white
Density of an aluminium block?
The density of an aluminum block typically ranges from 2.63 to 2.70 grams per cubic centimeter.
Block A and Block B are each in a beaker with water. Why does Block A sink and Block B float?
Block A sinks because its density is greater than the density of water, while Block B floats because its density is less than the density of water. Buoyancy force acting on an object is determined by the object's density relative to the density of the fluid it is in.
Why do some objects sink when placed water?
That Depends upon a principle Buoyancy.That means that the object placed in water should have density (particles per unit volume) less than that of water to float or else it will sink. Like when we will put a plastic block in water it will sink but when a bottle made of same plastic block is put in water it floats because it have comparatively lower density to the block due to air.
