Answer:
115060 J
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 500 g
Initial temperature (T1) = 20 °C
Final temperature (T2) = 75 °C
Change in temperature (ΔT) = 55 °C
Specific heat capacity (C) = 4.184 J/g°C
Heat (Q) required =?
The heat required to change the temperature of the water can obtained as follow:
Q = MCΔT
Q = 500 × 4.184 × 55
Q = 115060 J
Therefore, the heat needed to change the temperature of the water is 115060 J.
I believe it's gonna be B or C
According to google, one gallon equals 8.36 pounds. I took 8.36and divided by 0.00590 and got 1416.94915254 So if rounded to the nearest hundreth, 1416.95. I have no idea if I'm right. Sorry I couldn't do more!
