The first law of thermodynamics states that heat is a form of energy and thermodynamics processes are therefore subject to the principles of conservation of energy. The principle of conservation of energy on the other hand states that energy can neither be created nor destroyed, it can only be changed from one form to another.
The mathematical equation for the first law of thermodynamic states that
E = Q - W,
Where E = change in internal energy
Q = Heat added to the system and
W = Work done by the system.
This equation shows that, energy is conserved in the system, that is, the change internal energy of a system is a function of the heat added to the system minus the work done by the system. Thus, all the energy supply to the system has been accounted for and nothing is lost; this is in agreement with the principle of conservation of energy.
Answer:
club mosses
Explanation:
Microphyll is a type of plant leaf defined by the existence of a single non-branching rib. The present species that have microphiles have small and relatively simple leaves, associated with protosteal stems; however in the past there were representatives with microphiles up to one meter long. The most widely accepted theory about the origin of microfiles is that they evolved from lateral projections of the main axis.
Microphils are characteristic of club mosses, spike mosses, and quillworts leaves.
Answer:
The given blank can be filled with corona.
Explanation:
The Moon moves in between the Earth and the Sun in a solar eclipse. When this takes place, a segment of the light of the Sun gets blocked. During a total eclipse of the Sun, the corona of the Sun can be witnessed shining in all the orientations surrounding the Moon. The only time when the corona of the Sun can be witnessed is during a total solar eclipse. Colorful lights from the chromosphere of the Sun and the solar prominences are also visible at the time of a total solar eclipse.
Salinity is the concentration of dissolved salts in water. Density is the degree of compactness in a substance. By determining the salinity of a substance, you would also be determining the density.
Trees in the rainforest are so tall because they compete for sunlight. Hope this helps!
