`0^(@)C` তে 1 গ্রাম বরফকে `100 ^(@)C` তে বাষ্পে রূপান্তর করতে তাপ প্রয়োজন

0^(@)C : Melting point of ice : : 100^(@)C : ______ .

2g ice at 0^(@)C is mixed with 1 g steam at 100^(@)C . Find the final temperature of the mixture.

100 g ice at 0^(@)C is mixed with 10 g steam at 100^(@)C . Find the final temperature and composition .

A 1.0g sample of substance A at 100^(@)C is added to 100 mL of H_(2)O at 25^(@)C . Using separate 100 mL portions of H_(2)O , the procedure is repeated with substance B and then with substance C . How will the final temperatures of the water compare ? {:("Substance","Specific heat"),(A,0.60 J g^(-1) "^(@)C^(-1)),(B,0.40 J g^(-1) "^(@)C^(-1)),(C,0.20 J g^(-1) "^(@)C^(-1)):}

A carnot engine first works between 100^(@)C and 0^(@)C and then between 0^(@)C and -100^(@)C . What is the ratio of its efficiency in these two cases ?
