Physical and Chemical Changes in Hindi

[@minuagarwal780]

1 . a ) Physical change b) Chemical change c) Chemical change d ) Physical change 2) Cooking food is a chemical change because when food is cooked new substance is formed and it is irreversible reaction . 3 ) No new substance are formed in physical change . Most of the physical change are reversible. Example - Boiling of water On other hand new substance are formed in chemical change. Most of the reaction of chemical change are irreversible. Example- Cooking food .

Sir please upload more video for class 7th superb teaching ☺️

[@ruchibabel6822]

1=boiling of water and rusting of iron 2=cooking of food is chemical change because we don't get that food again

[@aryan-cl7en]

Boiling of water :-physical change Cooking of food:-chemical change Cutting of wood:-physical change Rusting of iron:-chemical change Respiration:-chemical change

[@jskarle7358]

1) A) physical change B) chemical change C) chemical change D) chemical 2) cooking of food is chemical change because as it involves the change in the composition of the food. After cooking, the raw ingredients of the vegetables cannot be regained. 3) Physical change is a temporary change. A chemical change is a permanent change. . Some examples of physical change arefreezing of water, melting of wax, boiling of water, . A few examples of chemical change are digestion of food, burning of coal, rusting Sir plz reply my answer

[@mkkhan1682]

Absolutely 😊😊😊

[@rizwanhadi5533]

Q2:- Yes, it is a chemical change. REASON:- For eg:- when we cook food add spices to a vegetable, the spices can't be seperated from the vegetable

Physical change - New physical formation can appearance. - Reversible in nature - Mass is constant Chemical change - No new physical formation - Irreversible - Mass is alternate

(1) Physical Change - boiling of water, cutting of wood Chemical change - rusting of iron, respiration (2) Cooking of food is chemical change. example - Making of bread, chappati (3) Physical change - no new substance formed, reversible, mass doesn't change. Chemical change - new substance made, irreversible, mass change

Yaa it's right 👍

[@jeminkukadiya13]

It’s almost right.

[@mannuphougat5717]

It's absolutely correct

[@jeminkukadiya13]

@@mannuphougat5717 Mistakes: Physical: boiling of water may change chemical property at micro level similarly, cutting of wood somewhat burn wood at micro level, cooking of food is physico-chemical change. Physical and chemical has no direct relation with Reversibility. Mass can change in physical reaction also. Possibly this one also almost correct.

In making lemonade can we get lemon juice and sugar back?then why it is consider as physical change aur yeh wapis reverse b nhi horaha hum lemon ko Pani se wapis kase nikalen

[@geetanjalivats2371]

Sometimes it is irreversible.

[@abdullah84290]

Mayebe by some sort of evaporation ,u can get ur lemon back!

[@renurajput859]

Q1. A) chemical change. B) chemical change. C) chemical change. D) physical change. Q2. Cooking of food is a chemical change because the ingredients we have used in making the dish/food cannot come back to their original form. Hence cooking of is a chemical change. Q3. Physical change :- 1. No new substance is formed. 2. They can be reversible. 3. A little energy is consumed and released. B). Chemical change. 1. New substance is formed. 2. They are irreversible. 3. Lot of energy is consumed and released.

in making lemonade, can we get lemon juice and sugar back?? then why this is consider as physical change?

[@amitavikram1135]

Yes, the lemon juice and sugar can be recovered from lemonade, which is why making lemonade is considered a physical change: No new substances formed When lemon juice and sugar are mixed with water, no new substances are created. The sugar and lemon juice simply dissolve in the water. Reversible The powder and water can be separated again by evaporation, demonstrating that this is a reversible physical change. No change in color, smell, or temperature Mixing lemon juice and sugar does not change the mixture's color, smell, or temperature.

[@sanjanagaur8145]

Sir question 1 a) physical change b) chemical change c) chemical change d) physical change Questions 2 Answer- it is chemical change because they produce new substances that are entirely new chemical compound Questions 3 Answer - physical change- they are reversible, new substances is not formed, mass is same Chemical change - they are irreversible, new substances is formed, mass is not same. Examples of physical change - melting of ice cube into water, dissolving of sugar into water Examples of chemical change- burning of magnesium, rusting of iron. Examples for reversible change- melting of ice and freezing of water Example for irreversible change-burning of magnesium Example for periodic change-change of seasons Example for non periodic change- change of weather Example for slow change-seed growing into a tree Example for fast change- occruing of lightning

Thank u so much sir your great ..l understand properly and l can do this 3 question 👍

[@sharmisthabasu1862]

Q1- rusting of iron and respiration are chemical properties because these are not reversible substances. Q2 - cooking of food is a chemical changes because while we cook food then gradually CO2 gas releases so it's forms a new substance that is carbon dioxide gas so it is chemical changes.100% i think so Q3 - chemical properties 1.= It forms new substance , large amount of energy release, mass of the substance changes . physical properties = does not form new substance,less amount of energy release,mass of the substance remaining same.
