Question

1 kg sample of aluminium is stored in a laboratory. In a different laboratory, in the same town, there is a 1kg sample of iron. Which quantity must these two samples always have in common?

Answer 1

Question -: 1 kg sample of aluminium is stored in a laboratory. In a different laboratory, in the same town,

there is a 1 kg sample of iron.

Which quantity must these two samples always have in common?

Same density

Same temperature

Same volume

Same weight

Answer - The quantity common in these two samples is - Same weight

• Density is defined as the mass of sample per unit volume. Density of a compound does not depend on the amount of substance. Hence, the same mass does not guarantee same density.
• Temperature is defined as the intensity of heat present in the object. It is an intensive property of an object and hence does not change with size or quantity of matter.
• Volume refers to the amount of space occupied by an object. Volume is an extensive property. It solely depends on the type of matter and does not depends on amount of object.
• Weight is the force exerted on body due to acceleration due to gravity. The weight states the quantity, which is same for both the elements. Thus, it is common.

Answer 2

These samples have the same weight in the common.

• The mass of the sample per unit volume is the definition of density. The amount of a chemical has no bearing on its density. The same mass does not, therefore, guarantee the same density.
• The amount of heat present in a thing is measured as its temperature. Since it is an intense property, it is unaffected by an object's size or mass.
• Volume is a measurement of how much space an object takes up. Volume is a broad category of property. It does not depend on the quantity of the thing; it only depends on the sort of matter.
• Weight is the force applied to the body as a result of the acceleration brought on by gravity. The quantity is indicated by the weight and is the same for both elements. Thus, it is common.
