This channel is probably gonna get me through chemistry this year

In our books there's only the formula of specific heat not what it is!!!!!!!!!!!

Ur mouse writing is good

Thank you for being my teacher

Thank you so much for your wonderful video! It is really helpful to me

SUMMARISED BY GPT-4: 1. Specific Heat: Specific heat is a property unique to each substance. It defines the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius. Different substances have different specific heats, meaning they require varying amounts of energy to change their temperatures. 2. Water vs. Sand: Water has a higher specific heat than sand, meaning it requires more energy to raise its temperature by one degree Celsius compared to sand. This is why, on a sunny day, sand on a beach gets much hotter than the water. 3. Calorie: The specific heat of water is termed as a "calorie". This is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. The video also clarifies the difference between the calorie used in food labels (which is actually a kilocalorie) and the calorie used in scientific contexts. 4. Impact on Climate: The high specific heat of water has significant implications for our climate. Coastal areas experience milder temperatures due to the moderating effect of water. During summer, coastal areas are cooler than inland areas because water heats up slower. Conversely, in winter, coastal areas are warmer because water retains heat longer and cools down slower. 5. Hydrogen Bonds: The reason water has a high specific heat is attributed to hydrogen bonding. When water is heated, some of the energy goes into breaking these hydrogen bonds, which means not all the energy is used to increase the kinetic energy of the water molecules. This hydrogen bonding "friction" allows water to absorb more heat without a significant rise in temperature.

You are the best teacher. Thanks!

This man is the only reason I'm not gonna fail the test tomorrow thank you khan academy you earned a new subscriber.

this fr helped, i have a biology in a few hours if i dont fail its all thanks to u

Sorry, can anyone explain me 7:37 "more energy goes in the water, the temperature changes less, and it can also radiate the same amount of heat, but also lose less temperatur" ? Radiate heat with lose less temperature, it dosent mean the less heat can radiate and then be colder m Thank youu.

THANK U SO MUCH THIS IS SO FUN TO LEARN WHEN U TEACH IT WITH drawings and examples lov it keep up the good work this is better than my teacher

This video is very helpful to students like us. Thank you very much.

Wonderful explanation! thanks.

Thank you sir

Excellent explanation👍

Isn't it 1kg...? Or is it different in America?

2 INTERESTING things. 1: when it comes to the number of sig figs used. physics books are Superior to chemistry books. My inorganic chemistry book they just top at 4.184 j/ blah blah blah i don't remember what my physics book stated but it didn't stop at 4 significant figures . 2: The specific heat of water was NOT THE SAME for each physics book. ya know year dependent; not same year different value. although i was to lazy to check that.

This was much and much helpful 😄👍

If in water ,hydrogen bond break then it mean that there is a chemical change

why is it sometimes the calculated specific heat capacity is lower than the real value 🤔🤔🤔

how can we calculate that the specific heat of water is 4.18l/gC

So water has a nutritional kcal value? What is it?

Very helpful, thank you! :)

Shout out to my chemistry teacher for hooking it up with the video for the midterm

Super helpful

Thank you

god he rambles so much lmao
