Heat Transfer: Basic Concepts What are Heat and Temperature? Heat is a form of energy transferred from one system to another due to a temperature difference. Heat is measured in joules (J) or calories (cal). Temperature, on the other hand, is a measure of the average kinetic energy of the molecules in a substance. Temperature is measured with a thermometer
A parabola is a geometric shape formed by the graph of a quadratic function, characterized by its symmetric and curved structure. This curve appears frequently in nature and engineering, playing a crucial role in fields such as physics, architecture, and optics. Key features of a parabola include its vertex, focus, and axis of symmetry, which determine its behavior and applications
Decimal Number Definition and Basic Features The Decimal Number System is a base-10 system represented by digits from 0 to 9 (0,1,2,3,4,5,6,7,8,9). This system, which we use in daily life, is also known as the Hindu-Arabic numeral system. Example: 7310 , 13210 , 526710 → The subscript indicates the base. Structure of Decimal Numbers 1. Whole Part and Decimal Part 2.
Definition and Examples of Functions Every scientific field has a vital role in establishing mappings between various objects or quantities. Such mappings enable predictions. In our daily lives, we encounter numerous examples of mappings: In each of these examples, there is a rule that maps elements of one set to elements of another set. These mappings are called functions. Definition
The Smallest Unit of Matter: Atom All food and cooking processes are built upon atoms and molecules. All living systems (animals, microbes, and smaller life forms) are composed of atoms and molecules. These atoms and molecules form the chemistry of life through how they organize, interact, and undergo reactions. To understand cooking and baking at the molecular level, it’s important
Consecutive numbers are sequences of numbers that follow a specific order in which each number is a fixed amount greater than the previous one. The most common form of consecutive numbers consists of integers increasing by 1, but there are also different types, such as consecutive even numbers, consecutive odd numbers, consecutive square numbers, and consecutive prime numbers. These sequences
Common divisors, the greatest common divisor (GCD), and the least common multiple (LCM) are essential concepts in mathematics that simplify problems involving fractions, ratios, and number theory. Grasping these concepts is vital for determining relationships between numbers and effectively solving real-world challenges. Common Divisor A common divisor is a number that divides two or more numbers exactly, without leaving a
Factors and Divisors of Natural Numbers Every natural number can be expressed as the product of two natural numbers. Each of these numbers is called a factor of the original number. Factors are also referred to as divisors, as they divide the number without leaving a remainder. Example: Positive Factors and Divisors of 24 The number 24 can be expressed
Positive and negative numbers form the foundation of arithmetic and are crucial in understanding various mathematical concepts.The understanding of positive and negative numbers allows us to perform basic arithmetic operations, such as addition, subtraction, multiplication, and division. They also help describe real-world situations, from calculating profits and losses in business to measuring below-zero temperatures. Mastery of these numbers is essential
Even and Odd Numbers Even and Odd Natural Numbers Many objects around us can be classified as either odd or even. Some of these objects are used individually, while others are used in pairs. Odd Numbers Even Numbers Warning: The factorials of odd numbers are 0 and 1. (0! = 1 and 1! = 1). The factorials of all other
