Answer:
I think your answer is either b or c but I think b is more likely to be your answer
In a system, heat that is gained and lost should be conserved. We calculate as follows:
Heat from phase change + sensible heat from the change in tempeture of the ice = sensible heat from the change in temperature of water
mH(fusion) + mCpΔT = mCpΔT
.05 (335) + .050(4.184)( T - 0) = .4 (4.184)(45 - T)
T = 34.8 °C

Explanation:
Answer:
D
Explanation:
according to boyle's law the temperature and pressure of a gas are inversely proportional given by the equation
p1v1=p2v2
In this case p1 is 9.5,v1 is 1.7,v2 is 1.1 and we have to find p2
9.5×1.7=p2×1.1
16.15/11=1.1p2/1.2
p2=14.7
I hope this helps
