I hope this helps answer your question. :)
These problems are very hard to do digitally so I would recommend trying to practice these types of problems on paper :)
It has a higher boiling point and a lower freezing point
Answer:
Q = 217.63J
Explanation:
Data;
Mass = 34.5g
T1 = 26.4°C
T2 = 75.3°C
c = 0.129J/g°C
Energy (Q) = mc(T2 - T1)
Q = 34.5 * 0.129 *(75.3 - 26.4)
Q = 4.4505 * 48.9
Q = 217.629J
Q = 217.63J
The heat gained was 217.63J
