Answer:
62760J
Step-by-step explanation:
Given parameters:
Mass = 0.5kg = 500g
Initial temperature = 30°C
Final temperature = 65°C
Unknown:
How much energy is absorbed by the water = ?
Solution:
To solve this problem, we use the expression below:
H = m C Δt
H = m x C x (t₂ - t₁ )
m is the mass
C is the specific heat = 4.184J/g°C
t₂ is the final temperature
t₁ is the initial temperature
So;
H = 500 x 4.184 x (65 - 30) = 62760J
