Answer:
7.06 x 10⁴ J
Step-by-step explanation:
To find the amount of heat necessary to heat the water, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = heat (J)
-----> m = mass (g)
-----> c = specific heat capacity (J/g°C)
-----> ΔT = change in temperature
The specific heat capacity of water is 4.186 J/g°C. You can plug the given values into the equation and simplify to find "Q".
Q = ? J c = 4.186 J/g°C
m = 225 g ΔT = 100.0°C - 25.0°C = 75.0°C
Q = mcΔT <----- Given equation
Q = (225 g)(4.186 J/g°C)(75.0°C) <----- Insert values
Q = 7.06 x 10⁴ J <----- Multiply
