A50g ice cube at 0 degrees celcius is added to a glass containing 400g of water at 45 degrees celcius. what is the final temperature of the system? you may assume that no heat is lost to the surroundings.

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

Conservation efforts have been effective in "increasing the number of endangered species, reducing all the negative impacts of human activity, and preserving wildlife habitats".hope my answer has you : )
