Answer:
1840 J
Explanation:
From the question given above, the following data were obtained:
Specific heat capacity (C) = 0.46 J/gºC
Mass (M) = 50 g
Initial temperature (T₁) = 20 °C
Final temperature (T₂) = 100 °C
Heat (Q) required =?
Next, we shall determine the change in the temperature. This can be obtained as follow:
Initial temperature (T₁) = 20 °C
Final temperature (T₂) = 100 °C
Change in temperature (ΔT) =?
ΔT = T₂ – T₁
ΔT = 100 – 20
ΔT = 80 °C
Finally, we shall determine the heat required. This can be obtained as follow:
Specific heat capacity (C) = 0.46 J/gºC
Mass (M) = 50 g
Change in temperature (ΔT) = 80 °C
Heat (Q) required =?
Q = MCΔT
Q = 50 × 0.46 × 80
Q = 1840 J
Thus, 1840 J of heat energy is required.

Hello, welcome to Brainly!
If we are to say that no heat was lost, we would have to write this down as a absolute function.
Beaker A lost 18 degrees in the span of 5 minutes (100 - 82) and Beaker B gained 18 degrees in the span of 5 minutes.
This is where the problem gets tricky, because we have no second value for the second line of the function, though I doubt this question is that complicated.
Now, what we do is we subtract 18 degrees from Beaker A, again, since 10 - 5 minutes is 5 minutes. We then add 18 degrees to Beaker B.
Answer:
Beaker A: 64° (82 - 18)
Beaker B: 36° (18 + 18)
