by size,volume and gravity
You cannot.
The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..
False
Density is the mass of an object divided by its volume. Without knowing the volume of the object, we cannot determine its density.
A weighing machine will give you the mass of an item. The weight of an item is the amount of force that an item exerts on the earths surface.
The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..
The device used for comparing the mass of an object to a known mass is a double pan balance, or a balance scale. This is a type of weighing scale where you put weights on one pan and the substance you are weighing on the other.
You compare its mass with something of known mass. In everyday earthbound conditions, this would mean weighing it on a set of weighing scales or on a spring balance.
The mass of an object can be determined by weighing it using a scale and then using a conversion factor to convert the weight measurement to mass. This conversion factor is usually the acceleration due to gravity (9.81 m/s^2 on Earth) which relates the force of gravity acting on the object (weight) to its mass.
When the weight of one object is found to be greater than the other. Either weighing up both by holding in your hands, or by weighing them on a scale. Obviously, if an iron bar is next to a piece of wood of the same size the iron would be the heaviest.
A weighing scale is used to measure the weight of an object or a person by using the force exerted by gravity on the object being weighed. It is commonly used in various settings such as households, industries, and laboratories to determine mass and ensure accurate measurements for a variety of applications.
A balance or scale is used to determine the mass of an object. The object is placed on the balance and its mass is measured in units such as grams or kilograms.
