Answer:
514 cal
Explanation:
In order to calculate the lost heat by the amount of water you first take into account the following formula:
[tex]Q=mc(T_2-T_1)[/tex] (1)
Q: heat lost by the amount of water = ?
m: mass of the water
c: specific heat of water = 1cal/g°C
T2: final temperature of water = 11°C
T1: initial temperature = 12°C
The amount of water is calculated by using the information about the density of water (1g/ml):
[tex]m=\rho V=(1g/ml)(514ml)=514g[/tex]
Then, you replace the values of all parameters in the equation (1):
[tex]Q=(514g)(1cal/g\°C)(11\°C-12\°C)=-514cal[/tex]
The amount of water losses a heat of 514 cal
