Answer:
It is a law because it is a statement of fact that does not need any more experimental support.
Explanation:
A hypothesis is an acceptable assumption that is formulated through the collection of information and data and that attempts to explain some phenomenon. In other words, a hypothesis is a conjecture with which one tries to explain an observed fact. The formulation of a hypothesis can be derived in two different ways: by generalization, from a certain number of cases or observed phenomena; and, by analogies observed in the occurrence of different phenomena.
A theory is something that attempts to explain some phenomenon and that is accepted as true by the scientific community. In other words, a theory is a set of rules that describe the behavior of a particular system.
A law is a statement that expresses the constant relationships between phenomena of nature, society or the mind. Scientific law can be defined as an invariable relationship of terms. In other words, a law is what is scientifically proven to be true, it is universally applicable.
So scientific theories and scientific laws are based on hypotheses. But a theory is the explanation of an observed phenomenon, while a scientific law is the description of an observed phenomenon.
The movements of bodies in space are governed by Newton's Laws. These are laws why they are demonstrated by mathematical formulas and Universal application.
Then, the correct option is <u><em>"It is a law because it is a statement of fact that does not need any more experimental support."</em></u>
The correct answer is d!!
122 moles of Methane to liters is 2734.5
Answer:
2.32 m
Explanation:
So, according to definition of mole fraction:
Mole fraction = 0.176
Applying values as:
So,
Also, Molar mass of toluene = 92.14 g/mol
Thus,
The formula for the calculation of moles is shown below:
Also, 1 g = 0.001 kg
So,
Molality is defined as the moles of the solute present in 1 kg of the solvent.
It is represented by 'm'.
Thus,
<u>Molality of benzene = 2.32 m</u>
Answer:
Water has high heat capacity to act as a thermal buffer against freezing.
The specific heat capacity of water = 4.2 joules per gram per degree Celsius or 1 calorie per gram per degree Celsius.
So, the vats of water will help in preventing the freezing of the materilas inside.
