Answer: There will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from to
.
Explanation:
Given: Mass = 45.0 g
Initial temperature =
Final temperature =
Formula used to calculate heat energy is as follows.
where,
q = heat energy
m = mass of substance
C = specific heat = (here, for water)
= initial temperature
= final temperature
Substitute the values into above formula as follows.
Thus, we can conclude that there will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from to
.
