We are asked to choose which would show the smallest temperature change upon gaining 200.0 J of heat among the given choices.
Step 1: Write the equation dealing with specific heat, mass, and change in temperature.
Step 2: Explain the relationship between specific heat and change in temperature, and between mass and change in temperature.
Step 3: Identify the answer.
Which of the following (with specific heat capacity provided) would show the smallest temperature change upon gaining 200.0 J of heat?
a. 50.0 g Al, CAl = 0.903 J/g°C
b. 50.0 g Cu, CCu = 0.385 J/g°C
c. 25.0 g granite, Cgranite = 0.79 J/g°C
d. 25.0 g Au, CAu = 0.128 J/g°C
e. 25.0 g Ag, CAg = 0.235 J/g°C
