1 gm of water at 20°C is heated till its temperature raises to 21 °C. The amount of heat energy absorbed by the water is ………………..

Observation : Sugar crystals separate out. Inference :  The sugar syrup solution prepared is a saturated solution.  Therefore, Additional amount of sugar cannot be dissolved in it at room temperature.  In a saturated solution, There exists...

Correct option is  A) mass

Correct option is  A) 4.186

Correct option is  C) c,d

Mass (m) = 2 kg = 2 × 103 g. latent heat of fusion for ice (L) = 80 cal/g. To find: Heat energy (Q) Formula: Q = mL From formula, Q = 2 × 103 ×...

 Q = mL so, L = Q/m. Hence, the correct option is (B) Q/m

Correct option is  D) 730 cal

(A) 136 km When the piece of ice falls from the height h, it possesses potential energy, mgh. This P.E. is converted to heat energy. ∴ Q = mgh But only \(\frac{1^{th}}{4}\) of it is absorbed...

C) Producers
