Answer:
0
Explanation:
Δk = (kf - Ki). Kf is 0 because your stopping it [m(v_i)^2 ]/2q = V

Given
V1 = 35L
T1 = 20.00 C = 293.0 K
V2 = ???
T2 = 45 C = 318 C
Formula
V1/T1 = V2/T2
Sub and Solve
45/293 = x / 318 Cross multiply
45*318 = 293x Divide by 293
45*318/293 = x
14310 / 293 = x
x = 48.84
Answer:
Endothermic
Explanation:
The temperature of the water decreased.
The water lost heat.
The heat must have gone into getting the KNO₃ into solution.
So, the dissolving of KNO₃ in water is endothermic.
Trisulfer-dodecacarbonide
