Number of particles
Number of particles
A substance sample contains a certain number of particles - domyhomework . The number of particles indicates how many particles are present in a substance sample or substance portion.
Formula symbol: N
Since each particle of a substance has a specific mass - https://domyhomework.club/chemistry-problem-solver/ , the greater the mass, the more particles are present in a portion of substance. The following relationship applies
N ~ m
Temperature of bodies
The temperature of bodies indicates how hot or cold a body is. Formula symbol: ϑ(Greek letter, pronounced:theta)
Units: one degree Celsius (1 °C)
one kelvin (1 K)
The units are named after the Swedish naturalist Anders Celsius (1701-1744) and after the British physicist Lord Kelvin of Largs, as William Thomson (1824-1907) was allowed to call himself after his elevation to the peerage.
With the heat-sensitive or cold-sensitive points in our skin we can feel whether air or water are hot, warm or cold. In the natural sciences, the property of bodies to be differentially hot or cold is described by the physical quantity temperature - do my php homework . The temperature of bodies indicates how hot or how cold a body is.
Formula symbol: ϑ (Greek letter, pronounced: theta)
Units: one degree Celsius (1 °C)
one kelvin (1 K)
Temperature differences are usually expressed in the unit Kelvin (abbreviation: K). The following therefore applies:
20 °C - 16 °C = 4 K or
293 °K - 289 °K = = 4 K
The following applies to the conversion of Kelvin into degrees Celsius:
ϑ°C=TK-273 ϑ temperature in °C T temperature in K
For the conversion from degrees Celsius to Kelvin applies:
TK=ϑ°C+273 T temperature in Kelvin ϑ temperature in °C

Working the search field (finding a proof idea)
When searching for proof ideas, two strategies can help: the so-called working forwards and the so-called working backwards - https://domyhomework.club/html-assignment-help/. When working forwards, one starts from the given premises and asks oneself a series of typical questions such as the following:
- What is known? What do we know about the figure?
- How can what is known be recorded mathematically and written down?
- What follows from the premises?
- What sentences with the same or similar premises are known?
- When working backwards, one starts from the assertion to be proved. Typical questions in this procedure are:
What is the name of the proposition?
Do you know sentences with the same or similar assertion? Which of these propositions have the same preconditions as the proposition asserted or can such preconditions be created?
For our proof problem at hand, working forward seems to be favourable - https://domyhomework.club/geometry-homework/ : Evaluating the presuppositions, show that 3 is a divisor of the sum and that 4 is a divisor of the sum. The assertion would follow from this.
(3) Carrying out the proof
Precondition:
p, p+2∈P; p+(p+2)=z
Assertion:
12 | z
Based on the example considered, the structure of the direct proof can be deduced:
From the premise of the proposition as well as already known facts - do my homework (definitions, theorems), the truth of the assertion is shown directly with the help of a finite number of valid rules of inference.
