We know that:
- It is a constant-pressure calorimeter
- the temperature of 60.0 g of water increases by 4.50 °C
- Specific heat capacity of water = 4.2 J/goC
And we must find the amount of heat that is transferred to the water.
To find it, we need to use the formula for heat absorbed
Where,
Q represents the heat absorbed by the water
m represent the mass
Cp represents specific heat, in this case of the water
(T2 - T1) represents the variation of the temperature
Using the given information, we know that:
m = 60.0 g
Cp = 4.2[J/(g°C)]
(T2 - T1) = 4.50 °C
Now, replacing in the formula
Finally, we can convert J to KJ
ANSWER:
B. 1.13 KJ
