water'density is __ so objects that are less than __ float and objects that are more than__sink.
The density of water is approximately 1 gram per cubic centimeter (g/cm³) at 4 degrees Celsius. Objects with a density less than 1 g/cm³ will float in water, while objects with a density greater than 1 g/cm³ will sink.
To calculate the density of an object, you need to know both its mass and volume. The formula for density is:
Density = Mass / Volume
To measure the mass of an object, you can use a scale or balance. Make sure to measure the mass in grams or kilograms.
To measure the volume of an object, you can use various methods depending on the shape and size of the object. For regular-shaped objects, such as a cube or rectangular prism, you can use a ruler or caliper to measure the dimensions (length, width, and height) and then calculate the volume using the formula:
Volume = Length x Width x Height
For irregular-shaped objects, you can use the water displacement method. Fill a graduated cylinder or any container with water up to a certain level. Note the initial water level. Submerge the object completely in the water, and measure the new water level. The difference in water levels is equal to the volume of the object.
Once you have the mass and volume of an object, you can calculate its density. If the density is less than 1 g/cm³, the object will float in water. If it is greater than 1 g/cm³, the object will sink.
