GIVE REASON

It becomes very cold as soon as snow starts melting in cold countries.Why?

WHY ICE IS USED TO COOL DRINKS AT 0DEGREE RATHER THAN WATER AT 0DEGREE

What is the difference between specefic heat and heat capicity

which expands more- brass or pyrex glass

How is natural gas formed?

• Latent heat of Fusion— the amount of heat energy supplied to a solid at its melting point, such that its state changes without any change in its temperature.

  I didn't understand this term how is it possible that heat energy is provided but tempreature remain same

 in our book:"I Discover : A text book of ICSE physics", this topic of Latent heat is given quite in detail so can you please describe it more

 can you define calorimetry?

 What are the advantages of high specific heat of water?

 what is fomentation?

Can you plese add a video or more information on this topic.

 use of water as its specific heat is higher

how does a pressure cooker help in cooking food fast, when in reality what it does is increase the boiling point of water under pressure?

Thank you Mr. Nitesh Kumar sir for clearing my doubt on the problem which I posted earlier.
