What is the difference between mass and weight of an object? (Short paragraph)
Mass and weight are two different physical properties of an object. Mass refers to the amount of matter present in an object, while weight is a measure of the force of gravity acting on an object. Mass is often considered a fundamental property of an object and remains constant regardless of its location in the universe. It is commonly measured in kilograms (kg). Weight, on the other hand, varies depending on the strength of the gravitational force in a particular location. It is measured in newtons (N) and is calculated by multiplying an object's mass by the acceleration due to gravity. Therefore, while mass is a scalar quantity, weight is a vector quantity since it has both magnitude and direction.
In science lab you are given the four substances listed below with their densities:
Honey = 1.42g/cm^3
Olive oil = 0.90g/cm^3
Water = 1.00g/cm^3
Ethyl alcohol = 0.81g/cm^3
You are asked to combine all four substances in a beaker and observe how they separate. List the order in which the four liquids separate, starting with the one on top to the one on the bottom of the beaker.
When the four substances are combined in a beaker, they will separate based on their densities. The substance with the lower density will float on top of the substance with the higher density.
In this case, the order in which the liquids will separate, starting from the top to the bottom of the beaker, will be:
1. Ethyl alcohol (0.81g/cm^3)
2. Olive oil (0.90g/cm^3)
3. Water (1.00g/cm^3)
4. Honey (1.42g/cm^3)
Something that has mass and occupies space is known as ______________.
Something that has mass and occupies space is known as matter.
The change from a gas to a liquid is called _____________.
The change from a gas to a liquid is called condensation.
The formula for density is
The formula for density is:
Density = Mass / Volume
It is typically measured in units such as kilograms per cubic meter (kg/m^3) or grams per cubic centimeter (g/cm^3).
What is the density of an object that has a mass of 34 grams and a volume of 17 milliliters? You may use a calculator if needed.
1. 0.5 g/mL
2. 51 g/mL
3. 578 g/mL
4. 2 g/mL
