Answer:
A) 50.0 g Al
Explanation:
We can calculate the temperature change of each substance by using the equation:
where
Q = 200.0 J is the heat provided to the substance
m is the mass of the substance
is the specific heat of the substance
Let's apply the formula for each substance:
A) m = 50.0 g, Cs = 0.903 J/g°C
B) m = 50.0 g, Cs = 0.385 J/g°C
C) m = 25.0 g, Cs = 0.79 J/g°C
D) m = 25.0 g, Cs = 0.128 J/g°C
E) m = 25.0 g, Cs = 0.235 J/g°C
As we can see, substance A) (Aluminium) is the one that undergoes the smallest temperature change.
