No. Volume must be carefully considered as well before you can, with certainty, so declare.
If, however, the volume either remains the same or increases, whicle the mass is reduced, then, and only then, can you declare density has decreased.
True. Scientists can use the measure of density to determine if an object will float or sink in a fluid. If the density of an object is less than that of the fluid, it will float; if the density is greater, it will sink.
An object that floats in water is less dense than the water it displaces. This means that the weight of the water it displaces is greater than the weight of the object itself, causing it to float. Objects that float have a density less than 1 g/cm3.
If any object displaces a weight of liquid equal to or greater than its own weight, it will float. If it displaces less weight, it will sink. This is true regardless of the density of the liquid. Stated formally: "Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." This is known as Archimedes' Principle.
True. An object will float if it is less dense than the fluid it is placed in, and sink if it is more dense. Density is a key factor in determining whether an object will sink or float.
No, it is not true that heat transfer by the movement of currents within a fluid is called density; it is actually called convection. Density is something else entirely, it refers to weight per a given volume. Of course, density is relevant to convection. Heat causes fluids to expand and therefore to become less dense, and therefore to rise.
True. Scientists can use the measure of density to determine if an object will float or sink in a fluid. If the density of an object is less than that of the fluid, it will float; if the density is greater, it will sink.
True ~ Apex The answer is right there in the question. The density of any floating object is less than that of the fluid in which it floats.
The less mass in a given volume of air, the lower the air density. This means the air is less dense, or lighter, in that volume compared to air with more mass. Air density affects various aspects of weather and climate, such as air pressure and the formation of clouds and precipitation.
Because their density is less than the density of coke. And if that's not true of the object, then it sinks.
Yes. It is true that lighter airplanes fly farther. More weight means more down thrust is acting on the plane. This means traveling less distance. But less weight means less downthrust. So the airplane flies farther.
True... warm water is less dense than cold water.
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
An object that floats in water is less dense than the water it displaces. This means that the weight of the water it displaces is greater than the weight of the object itself, causing it to float. Objects that float have a density less than 1 g/cm3.
Usually yes; but depending on the metal, the density can be anywhere from less than one (kg/liter, i.e., the density of water), to about 20.
If any object displaces a weight of liquid equal to or greater than its own weight, it will float. If it displaces less weight, it will sink. This is true regardless of the density of the liquid. Stated formally: "Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." This is known as Archimedes' Principle.
Yes, that is correct. The molar mass of an element is directly proportional to its atomic weight. Lighter atoms have lower atomic weights, which means that one mole of a lighter atom will have less mass compared to one mole of a heavier atom.
No. Objects will only float in water with a density that is less than 1. This is not always true if another substance is in the water, such as salt.
