NEET Physics Temperature & Heat MCQ Question

Type: MCQ-numerical-Easy-Class 11

What is the heat required to convert 2 kg of ice at 0°C to steam at 100°C?

A

6.066 × 10^6 J

B

7.5 × 10^6 J

C

55 × 10^6 J

D

5.3 × 10^6 J

Correct Answer

Option A

Detailed Explanation

The total heat is calculated by adding the heat required for each phase change and temperature change: Q1 = mLf = 2 × 3.35 × 10^5, Q2 = msΔT = 2 × 4186 × 100, Q3 = mL = 2 × 2.256 × 10^6. Sum these to get 6.066 × 10^6 J.
