If an object is 3 times as dense as water with a mass of 5g with water what is the mass in air?
An object with a mass of 5 grams has a mass of 5 grams whether it's in water, air, ice, stone,
maple syrup, plasma, or scotch whiskey, and whether it's on earth, on the moon, inside Halley's
Comet, or out in space, and regardless of its density. Mass is mass, and at any speed much less
than the speed of light, mass doesn't change.
What else can I help you with?
When should an object float into a liqud?
An object will float when it has less density than the fluid or substance that it is placed in. The object floats upward due to buoyant forces. Similarly, objects will sink if they are dense than the fluid.
How can you tell if a material is less dense then water?
Density is mass per unit volume, so if you know an object's mass and the space it occupies, then you can calculate its density. If you had a scale, you could weigh the object to determine its mass. (Note that mass is not the same as weight, but the two are closely related insofar as we use weight to determine mass.) You could then carefully submerge it completely in water to determine how much water it displaced. That would tell you its volume. You would then divide the mass by the volume to get its density. But what if you don't have a scale? Can you still determine its density? I think you can. Place a known quantity of water in a graduated container. Carefully place the object in the container and note the change in the water level. Subtract the new water level form the old. That is the amount of water displaced by the object, which should be floating since it's less dense than the water. The weight of the water displaced by the object is equal to the buoyant force pushing up on the object. What does this tell us? Well, since the object floats, we know that the buoyant force is equal (but opposite) to the weight of the object. In other words, if we know the magnitude of the buoyant force, we know the object's weight (and therefore its mass)! Now, you can divide its mass by its volume, which you determined earlier by fully submerging it. Determine how much water is displaced by the floating object. Then carefully fully submerge the object and record how much water is displaced. If you divide the first number by the second, you will know its relative density compared to the density of water! If the floating object displaces 100 ml of water and the fully submerged object displaces 150 ml, then the relative density is 100/150 = 0.667. Since the density of water is 1.00 g/cm3, that means the density of the object is 0.667 g/cm3.
Why does mercury have a higher density than water?
Mercury is a metal that is liquid at room temperature. Metals are generally heavy, dense, closely packed materials. The molecular mass of water (H2O) is (2x1) + 16 makes 18. The molecular mass of mercury is about 201. Mercury is about 11 times as dense as water.
What is created when a mass of more dense water sinks beneath less dense water?
When a mass of more dense water sinks beneath less dense water, it creates a process called deep-water formation. This vertical movement helps in the redistribution of heat and nutrients in the ocean, playing a crucial role in ocean circulation and global climate regulation.
What is the amount of mass of an object compared to its volume?
Mass is the amount of matter in an object. It is not the same as weight, and cannot be calculated in the same way. To figure out the mass in a given volume, multiple the volume times the density.
How can you predict if something will sink or float?
An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
How can you predict whether objects will float or sink?
The density of water is 1 g/cm cubed, and objects more dense that water will sink, while objects less dense than water will float. An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
When should an object float into a liqud?
An object will float when it has less density than the fluid or substance that it is placed in. The object floats upward due to buoyant forces. Similarly, objects will sink if they are dense than the fluid.
How do you find density of an object in water?
To find the density of an object in water, first measure the mass of the object using a scale. Then, measure the volume of the water displaced by the object when it is submerged. Divide the mass of the object by the volume of water displaced to calculate the density of the object in water.
How can you predict whether an object will sink or float?
The density of water is 1 g/cm cubed, and objects more dense that water will sink, while objects less dense than water will float. An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
How does an object's density determine whether the object will sink or float in water?
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
What does it mean to be less dense than water?
Being less dense than water means that an object will float on water. This occurs when the object's mass per unit volume is lower than that of water. Objects less dense than water will displace an amount of water equal to their weight, causing them to float.
Why is a dense object heavy?
In a way that's what dense means. If something is dense then a small volume of it will have lots of mass. Something that has lots of mass will be subject to considerable gravitational force, which is weight.
How do the least dense particles move to the bottom of a liquid?
This question is misguided. Density is a property which pertains to the entire substance, not to particles. It is the mass per unit volume. In general it is more dense substances which sink. Thus grains of sand will sink in water. In order to float, an object has to displace a volume of water whose mass is the same as the object. If the object is more dense than water, by definition it cannot do this, so it sinks.
What is the desnity of an object that has a mass 350 g and a volume of 95 cm's 3 Would this object float in water Explain?
It would sink because the object is more dense than the water.
Does an object that's dense heavy for its mass or density?
An object that is dense has a large amount of matter within a given volume, regardless of its mass. Density is a measure of how tightly packed the matter is in an object, not the overall weight. So, an object can be dense but not necessarily heavy for its size.
Will kilogram float in water why?
The mass of an object alone is not enough to determine whether it will float in water. You need to know the object's mass and its volume; in other words, its density. A kilogram of solid lead will sink in water. A kilogram of styrofoam will float. If an object is less dense than water it will float; if it is denser it will sink.
