Plz tell k ab electrolytic cell and galvanic cell mdcat k syllabus mein nhi hain na? Plzzz tell me im confused

Who is preparing For MDCAT 2025?

Can we say covelent bond is 5 time stronger than hydrogen bonding

mashallsah

C and d

ya sindh corse hy plz tell me?

Sir you are the best teacher

Great sir❤

Aoa Sir, lecture no.1 Kahan hai iss chapter ka

The moment when sir said,"Main hon na"....took my all doubts and depression of gap year away 🥺greatest teacher in the world 🌍🎉 lots of prayers for you sirr ❤

The confusion here arises due to the way **specific heat capacity** and **heat capacity** are defined: 1. **Specific Heat Capacity (\( c \))**: This is the amount of heat required to raise the temperature of **1 gram** of a substance by \( 1 \, \text{K} \) (or \( 1 \, \degree \text{C} \)). For water: \[ c = 4.2 \, \text{J/g·K} \] This value remains constant regardless of the mass. 2. **Heat Capacity (\( C \))**: This is the amount of heat required to raise the temperature of an entire **sample** by \( 1 \, \text{K} \). It depends on the mass of the substance and is given by: \[ C = m \cdot c \] where \( m \) is the mass of the substance. ### Explanation for the given cases: - **For 1000 g (1 kg):** Using \( C = m \cdot c \): \[ C = 1000 \, \text{g} \cdot 4.2 \, \text{J/g·K} = 4200 \, \text{J/K} \] This means it takes \( 4200 \, \text{J} \) to raise the temperature of 1000 g of water by \( 1 \, \text{K} \). - **For 100 g:** Again, using \( C = m \cdot c \): \[ C = 100 \, \text{g} \cdot 4.2 \, \text{J/g·K} = 420 \, \text{J/K} \] This means it takes \( 420 \, \text{J} \) to raise the temperature of 100 g of water by \( 1 \, \text{K} \). ### Conclusion: The specific heat capacity (\( c = 4.2 \, \text{J/g·K} \)) remains constant regardless of the mass. However, the **total heat capacity** depends on the mass of the water being heated.

Best chem sir ever 😇 If ghool k pilana had a face 😇

Sir energy equation shows that when value of n increases energy also increase

I have never seen a teacher like that

sir 1 degree Celsius 1 Kelvin k equal kesy h ?

Let's break it down: 1. **Bonds in a Reaction**: In any chemical reaction, bonds in the reactants must be broken, and new bonds are formed in the products. 2. **Exothermic Reaction**: This is a type of reaction where energy is released (usually in the form of heat) to the surroundings. Examples include combustion and respiration. 3. **Why More Bonds Are Formed than Broken**: - When a reaction is **exothermic**, the energy released by the formation of new bonds is **greater** than the energy needed to break the bonds in the reactants. - This means that **more energy is released when new bonds are formed** than the energy that was used to break the bonds in the reactants. - Since energy is released, the products are more stable than the reactants, and the system loses energy (hence, it's exothermic). In simple terms: - More bonds are **formed** because the total energy released in forming these bonds is greater than the energy required to break the bonds in the reactants. Does this help clarify?

Op : A wrong bcz 1C+273.15=274.15K Op : D wrong bcz 32°F=273.15K Jazak Allah sir . May Allah Bless You!

Great celebratity and also great motivational speaker sir thank you ❤❤❤❤❤❤

MashAllah ❤❤❤❤

❤❤❤❤

You are great sir .. I'm from class 11th ... But I take your lectures permanently... But now I have no time .. papers.. test session 😕

Sir Allah ap ko khush raky ❤❤

What a tutor you are unexplainable ❤❤

Master piece ❤❤❤

Great teacher

One of the best teacher of chemistry

Sir Pdf note

Thank u so much sir ji ❤

sir everything is understood about allotrpy but still question rise that we have two elements such as dioxygen (o2) and ozone (o3) like sir you said that there can be more than one form but these two are diffrent elemnts although they are allotropes of each other plx sir need feedback .

❤❤❤

Sir hum wait karga or zarrori be join karga god bless you

Assalamualaikum sir my best teacher sir wajid Ali kamboh sir ap best teacher ho

Wonderful ❤

U are my dear student 😃
