If the dry mass of the grass from 1 m² of a field is found to be 0.2 kg, we can say that the grass has a dry mass (i.e. biomass) of 0.2 kg m⁻² (this means 0.2 kg per square metre). If the grass field is 200 m² in size, then the biomass of the whole field must be 40 kg (0.2 x 200 = 40) It is possible to estimate the biomass of organisms in ...
Jan 10, 2024 · Mass is the amount of matter in a body or a measure of its inertia. Mass is a fundamental concept in science. Basically, it is the amount of matter in an object. It’s an intrinsic property that is independent of an object’s location or the arrangement of the matter within it. Unlike weight, mass doesn’t change when an object’s position ...

Dec 9, 2023 · Definition and Statement of the Law of Conservation of Mass. The Law of Conservation of Mass was first articulated by Antoine Lavoisier in the late 18th century. It asserts that the total mass of a closed system remains constant over time. This principle is widely applicable in chemical reactions and also applies to other disciplines.
Mass balance is a fundamental concept in physiology that refers to the balance between the input and output of substances in the body to maintain homeostasis. In the context of human physiology, mass balance ensures that the total amount of a substance within the body remains constant over time, unless it is intentionally altered.

The mass defined in this way is the gravitational mass. In the 19th century Lóránd Eötvös (1848–1919) showed experimentally that gravitational and inertial mass are indistinguishable, i.e. mi = mg. Experiments performed in the 20th century have confirmed this conclusion to even greater accuracy.Although mass is formally defined in terms of its inertia, it is usually measured by gravitation.
