Final answer:
The specific heat capacity of the ring is calculated by using the formula q = mcΔT and the given values: q = 30.0 calories, m = 6.7 grams, and ΔT = 20°C, resulting in a specific heat capacity of 0.224 cal/g°C.
Step-by-step explanation:
To calculate the specific heat capacity of the ring, we use the formula:
q = mcΔT
Where q is the heat energy in calories, m is the mass in grams, ΔT is the change in temperature in degrees Celsius, and c is the specific heat capacity in calories/g°C. We rearrange the formula to solve for c:
c = q / (mΔT)
The problem gives us:
- q = 30.0 calories
- m = 6.7 grams
- ΔT = 20°C
Plugging these values into the equation, we get:
c = 30.0 cal / (6.7 g × 20°C)
c = 30.0 cal / (134 g°C)
c = 0.224 cal/g°C
Therefore, the specific heat capacity of the ring is 0.224 cal/g°C.
