NEET Physics Temperature & Heat MCQ Question
Type: MCQ-numerical-Medium-Class 11
A 1 kg block of copper is heated from 25°C to 100°C. How much heat is absorbed by the copper block? (Specific heat of copper = 0.39 J g⁻¹ K⁻¹)
A
29325 J
B
29250 J
C
27000 J
D
30000 J
Correct Answer
Option A
Detailed Explanation
The heat absorbed is calculated using the formula Q = mcΔT, where m is mass, c is specific heat, and ΔT is temperature change. Using m = 1000 g, c = 0.39 J g⁻¹ K⁻¹, and ΔT = 75 K, we get Q = 1000 * 0.39 * 75 = 29325 J.
