TEMPERATURE AND IT'S MEASUREMENTS What definition of temperature do you know? Let's begin that way * Definition of Temperature * * Temperature: * is the measure/degree of Hotness or Coldness of a body. It decided the way heat would flow when two bodies are in contact. It flows from a body with a higher temperature to a body with a lower temperature. The temperature scales used to measure temperature are: >Celcius scale (°C) >Farenheit Scale (°F) >Kelvin Scale (K) * The Celcius Scale * : is graduated from 0°C(lower fixed point) to 100°C(upper fixed point) * The Farenheit scale * is graduated from 32°F(Lower fixed point) to 212°F(Upper fixed point) * The Kelvin Scale * is graduated from 273k(lower fixed point) to 373k(Upper fixed point) * Example * : A Celcius temperature scale was used to measure an environ and it measures 54°C. What is the absolute temperature on the instrument if the upper and lower fixed point of that environ is 350°C...

WORD FORMATION (Morpheme)  *Word formation* refers to the way in which new words are formed in the basis of other words or morpheme.  And a morpheme is meaningful linguistic unit consisting of a word that cannot be divided into smaller meaning parts  _There is a difference between a morpheme and a word_  ▪️ *A word* can stand alone and can be meaningful but *a morpheme* can not always stand alone ▪️ *A word* can have 2 or more morphemes   ```LET ME GIVE EXAMPLE```   *RECONSTRUCT*    This is a word that has two morphemes (RE/CONSTRUCT).   When we have a sentence, it consists of clause. ⚡Clause consists of phrase ⚡Phrases consists of words ⚡And words consist of morpheme ⚡Morpheme consists of syllables   *Define a phrase*    Group of words without finite verb. So we can break this to phrase They/ might be thinking/of words/ and their meaning   Each of these phrases consists of one or two words   So words can be broken to...

  CHEMICAL KINETICS *Kinetics*: It studies the rate at which chemical processes occurs Aside the information about the speed at which reaction occurs, kinetics also shed light on the _reaction mechanism_ i.e exactly how the reaction occurs    *CHEMICAL KINETICS*  This is therefore the study of reaction rates or how fast a reaction proceeds. Reaction rates are generally measured as increase in concentration per time.  It could be mathematically expressed as:  ➖➖➖➖➖➖➖➖➖➖➖➖     *Rate of Reaction = Change in Concentration / time*   *Rate of Reaction = ∆(A) / t = d(A)/dt*  ➖➖➖➖➖➖➖➖➖➖➖➖    *REACTION RATES* Rate of reactions can be determined by monitoring the change in concentration of either reactants or products as a function of time, t.   Reaction Rate is also the change in concentration of the reactant or a product with respect to time, t.  For example, A -----> B Rate = -∆(A) / ∆t.       ∆A ...

* ATOMIC THEORY * What do you understand by the word ATOM? [5/26, 20:23]  Paul 100l: Smallest particle of an element that can take part in a chemical reaction * THE STRUCTURE OF MATTER * Electricity is the investigation of the forces created by charged particles, especially electrons, and the motion and interactions of those particles. * THE ELECTRON * is a fundamental component of matter and is composed of matter and is considered to have the smallest possible unit of negative charge. In comparison to ordinary visible objects in our environment, the electron is an extremely small particle having a mass of only 9.109 × 10^-31 kg * ATOMIC STRUCTURE * All matter is composed of * atoms * , each of which has a central * nucleus * like satellites around the earth. * The nucleus * contains one or more positively charged particles called * protons * The positive charge of a proton is "opposite" to the negative charge of an election, in the sense tha...

* PROJECTILE🏹🏓 * ``` Definition of a Projectile ``` A * Projectile * may be defined as a body or an object that's been propelled(projected) by the application of an external force in which the object then moves freely under the action/influence of gravity Let us take a look at the concept of projectile in this manner as when a boy releases a piece of stone from his catapult against a bird perching on a tree branch, the stone travels in a parabolic path towards the bird That's an example of a projectile motion A * Trajectory * is a Parabolic path with which a projectile moves or travels * Examples of Projectile Motion are: * 🔫A bullet from a fired gun 🏹A Stone or arrow released from a catapult 🤸🏻‍♂️An Athlete doing the high jump 🤾‍♀️A thrown rubber ball rebouncing from a wall 🏓A tennis ball thrown against a wall ⚽When we throw a ball from the top of a building >A stone released from a catapult against a bird on a tree Let's take a loo...
