Answer :
Final answer:
To calculate the amount of heat absorbed by the water, use the formula Q = mcΔT. The amount of heat absorbed by the water is approximately 127.03 kJ (option 'E').
Explanation:
To calculate the amount of heat absorbed by the water,
we can use the formula Q = mcΔT,
where Q is the heat absorbed, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature.
First, convert the mass of water from kg to grams: 0.46 kg = 460 g.
Then, calculate the change in temperature:
ΔT = final temperature - initial temperature = 74.6°C - 8.5°C = 66.1°C.
Finally, calculate the heat absorbed:
Q = (460 g) × (4.18 J/g°C) × (66.1°C) = 127,026.8 J = 127.03 kJ (rounded to two decimal places).
The amount of heat absorbed by the water is approximately 127.03 kJ. Hence, option 'E' is correct answer.
