NEET 2014 Physics Calorimetry MCQ Question
Type: MCQ-numerical-Medium-Class 11
Steam at 100 °C is passed into 20 g of water at 10 °C. When water acquires a temperature of 80 °C, the mass of water present will be (Take specific heat of water = 1 cal g⁻¹ °C⁻¹ and latent heat of steam = 540 cal g⁻¹)
A
24 g
B
31.5 g
C
42.5 g
D
22.5 g
Correct Answer
Option B
Detailed Explanation
Using the principle of calorimetry, the heat lost by steam is equal to the heat gained by water, allowing calculation of the final mass of water.
