Answer:
The answer to your question is the letter b. Q = 836 J
Explanation:
Data
mass of water = 40 g
C = 4.18 J/g°C
Temperature 1 = 20°C
Temperature 2 = 25°C
Q = ?
Formula
Q = mC(T2 - T1)
Process
1.- To find the value of energy moved to the surroundings, just substitute the values in the formula and simplify.
Q = (40)(4.18)(25 - 20)
Q = (167.2)(5)
Q = 836 J
2.- Conclusion
The energy moved to the surroundings is 836 J.
