What else can I help you with?
Would you expect to change a liquid's density?
The temperature of the fluid
Would you expect to get the same value for the density of a liquid at 20 degrees Celsius and at 40 degrees Celsius?
No, the density of a liquid usually decreases as temperature increases because rising temperature causes molecules to spread out. Therefore, you would generally expect the density of a liquid to be lower at 40 degrees Celsius compared to 20 degrees Celsius.
Would decreasing the amount of liquid to determine density change the outcome?
No, the amount of a liquid is volume. Density is independent of volume.
What would a density gradient look like?
A density gradient is a gradual change in density of a substance over a distance. In a liquid, it would appear as layers of varying density, with the highest density at the bottom and lowest density at the top. In a gas, it would result in a gradual decrease or increase in density over distance.
How can you make layers of water float on each other?
The best way would be to change the state of the water. In other words, have ice floating in liquid water, while steam is above that.
Does water density change?
yeah.....it does change when you add some liquid to it......
Does the density of a liquid change with the shape of a container?
No. the density is a characteristic of the liquid itself and not dependant on the container holding the liquid. Think of it this way: would the boiling point of a liquid change with the shape of a container? Another thought: think of a very rich, dense chocolate cake, as opposed to a very light angel food cake. You can have a very thin slice of the chocolate cake, or a ridiculously decadent slab. both pieces have the same quality of denseness, even if one is much more fun to eat.
How would force of buoyancy change for bodies weighing lesser?
The buoyant force is equal to the 'weight' of liquid that is displaced, which depends on the volume of liquid that is displaced, the density of the liquid, and gravitational acceleration, not the weight of the body.
Explain how can you find the density of an unknown liquid if you have all of the laboratory equipment you need?
To find the density of an unknown liquid, you would first measure the mass of a known volume of the liquid using a balance. Then, you would measure the volume of the liquid using a graduated cylinder. Finally, divide the mass by the volume to calculate the density of the unknown liquid.
How would heat change the density of a parcel of air?
how heat would change the density of a parcel of air?
Does density change if some of the liquid evaporates between the time the liquid is delivered to the beaker and to the time it was measured?
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
Would an object float at 3.684 density?
It isn't clear what units you are using, what liquid you are placing it in, and whether that is the density of the object or of the liquid. The general rule is that an object will float if it has less density than the liquid in which it is placed.
