Answer:
The correct answer is - 0.054 kg
Explanation:
Given:
change in temperature: 55°C
Heat energy = 12500 J
specific heat = 4.186
Formula:
The formula for Heat Energy is given by:
Q = mcp∆T
here: Q - Heat Energy
m is for mass
cp is for specific heat
∆T is a change in temperature,
Solution:
From formula,
m = Q/ cΔT
Mass = 12500 / (55 × 4200)
= 0.054 kg or 54 g
