Question

Calculate the quantity of heat absorbed by 15.0 g of water when heated from 20.0 °C to 50.0 °C given that Cs = 4.18 J/(g·°C).
Options
A 1.25 × 10³ J
B 1.88 × 10³ J
Correct Answer
C 3.14 × 10³ J
D 4.18 × 10³ J
Correct Answer

Option B is the correct answer.

Detailed Explanation

q = m * Cs * ΔT = 15.0 g * 4.18 J/(g·°C) * (50.0 - 20.0) °C = 1,881 J = 1.88 × 10³ J.
