What equipment do you need to work out the density of a pebble?
Explanation: A graduated cylinder is needed to measure the volume of a pebble.
How you would go about finding the density of a small rough pebble?
The density of the pebble is mass/volume. -To find the volume of the pebble: place a certain amount of water in the graduated cylinder without anything in it. Record the volume of that. Then, place the pebble inside the cylinder and record the volume of that.
How do you calculate density density?
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre.
What is the density of humans?
1000 kg/m^3
Which rock is most dense?
Two of the heaviest or densest rocks are peridotite or gabbro. They each have a density of between 3.0 to 3.4 grams per cubic centimeter. Interestingly, peridotite are the rocks that naturally occurring diamonds are found in.
What is the density of Earth?
5.51 g/cm³
What is the density of Earth in KG?
5515 kg.m
What is the formula of density of Earth?
Density is found by dividing the mass by the volume (ρ = m/V). A scientist named Henry Cavendish is known for calculating the mass (and then density) of the Earth.
What planet has the highest density?
Earth
Which planet has the longest year?
Neptune
What planet has the lowest density?
Saturn
What is the least dense planet?
What is the hottest planet?
Venus
What makes a planet dense?
If density is greater, the object sinks. Saturn is mainly composed of the lightest two gases known, hydrogen and helium. It is the only planet in our solar system whose density is less than water….Planetary Densities.
| Planet | Average Density (gm/cm3) | Required Mass for 70 cm3 (gm) |
|---|---|---|
| Neptune | 1.6 | 112.0 |
What is the lightest planet in our solar system?
What makes Jupiter so dense?
Density, mass and volume Known as a gas giant, Jupiter is composed primarily of hydrogen and helium. Although it is significantly more massive than Earth, it is only a fifth as dense, at 1,326 kg/m3, because it is made of gas rather than rock.
