7th class science : Weather, Climate and Adaptation of Animals to Climate

Weather: The day to day condition or temperature of the atmosphere at a specific place is called a weather. The weather can be too hot or cold, calm or stormy, wet or dry, clear or cloudy.

Weather Report: The periodic report about the weather,generally released by the meteorological department is called a weather report. Oftenly, the Weather report is shown along with the news on television.

Elements of weather: The miscellaneous elements of the weather are: temperature, humidity, pressure, rainfall, wind-speed, etc.

Temperature: Temperature of the earth depends upon the duration of sunshine. During the summer season, the span of the sunshine is longer. Due to this, the temperature is high in summer. The temperature is minimum in the morning and maximum at noon.

Humidity: Humidity is the amount of water vapors present in the air. Humidity is measured in percentage (%). During rainy season, humidity is at the highest level.

Magnetic and non-magnetic material Class 6 Science

Magnetic and non-magnetic material Class 6 Science A magnet is a substance that is drawn to certain magnetic materials like iron, cobalt, and nickel. Magnets have the ability to draw iron to them. Natural magnets are rocks that naturally draw iron. Non-magnetic materials include things like wood, rubber, coins, feathers, leather, etc. that are not drawn to iron. Magnet characteristics It pulls magnetic materials, such as iron. The magnet's two ends are referred to as its poles. The magnet's diametrically opposed poles are drawn together. Heating, hammering, or dropping causes it to lose its characteristics. On the basis of properties types of Magnets Temporary magnets are those magnets that are magnetic for only a little duration. Typically, iron, cobalt, or nickel are used to make them. When they are close to the powerful magnet, they act like a magnet. When they are yanked away from the powerful magnet, they stop being magnetic. Permanent magnets are magnets that have magne...

Look at these pairs of words: Bus – Buses Brush – Brushes Continue ..... Click here ...

What are Noble Gases? Example and noble gases name

What are Noble Gases? Example and noble gases name Noble Gases Noble gases, sometimes known as inert gases or erosions, are part of the modern periodic table's 18th group. This group is made up of the following individuals: Helium is a kind of gas (He) Neon (Ne) Argon is a gas (Ar) Krypton (Kr) Xenon is a kind of xenon gas (Xe) Radon is a gas that can cause cancer (Rn) Noble gases exist in a gaseous state under typical temperature and pressure conditions. Because all noble gases have stable electronic structures, they have very little chemical reactivity. They are monoatomic gases that do not readily form molecules. 'ns2np6' represents the basic electrical configuration of noble gases. As a result, noble gases' outermost valence shells can be deemed 'complete.' The chemical inertness of the group of 18 elements is due to this. Because of the stability of certain elements, these gases form a group. These stable elements' crusts are totally filled.
