A 5.00-g sample of liquid water at 25.0 C is heated by the addition of 84.0 J of energy.The final temperature of the water is ________°C.The specific heat capacity of liquid water is

Question

Quizplus · Accepted Answer

Using the formula Q = m * c * ΔT, where Q is the heat energy transferred, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature:

84.0 J = 5.00 g * 4.184 J/g°C * ΔT (since the specific heat capacity of water is 4.184 J/g°C)

ΔT = 4.02°C

Adding this to the initial temperature of 25.0°C gives a final temperature of:
25.0°C + 4.02°C = 29.0°C

Therefore, the best choice is D) 29.0.
