Look at the chart below.
Metal Specific heat (J/g°C)
Calcium (Ca) 0.647
Iron (Fe) 0.449
Silver (Ag) 0.235
Gold (Au) 0.129
If the same amount of heat is added to 25.0 g samples of each of the metals in the chart, which metal will experience the largest temperature change?
A
Ca
B
Fe
C
Ag
D
Au
To determine which metal will experience the largest temperature change, we can compare the specific heat of each metal. The metal with the lowest specific heat will experience the largest temperature change when the same amount of heat is added.
From the given chart, we can see that the specific heat of each metal is as follows:
Calcium (Ca): 0.647 J/g°C
Iron (Fe): 0.449 J/g°C
Silver (Ag): 0.235 J/g°C
Gold (Au): 0.129 J/g°C
Comparing these values, we can see that gold (Au) has the lowest specific heat of 0.129 J/g°C. Therefore, gold (Au) will experience the largest temperature change when the same amount of heat is added.
The correct answer is choice D:
Au
To determine which metal will experience the largest temperature change when the same amount of heat is added, we need to compare the specific heat of each metal. The metal with the lowest specific heat will experience the largest temperature change.
Looking at the chart, we can see that the specific heat values for each metal are as follows:
Calcium (Ca): 0.647 J/g°C
Iron (Fe): 0.449 J/g°C
Silver (Ag): 0.235 J/g°C
Gold (Au): 0.129 J/g°C
Comparing these values, we observe that gold (Au) has the lowest specific heat of 0.129 J/g°C. Therefore, gold will experience the largest temperature change when the same amount of heat is added.
Therefore, the answer is:
D
Au
To find out which metal will experience the largest temperature change, we need to compare their specific heats. Specific heat is the amount of heat required to raise the temperature of a substance by 1 degree Celsius.
In this case, the same amount of heat is added to 25.0 g samples of each of the metals. The heat added will be the same for all the metals.
To calculate the temperature change, we can use the formula:
Temperature change = Heat / (Mass * Specific heat)
Let's calculate the temperature changes for each metal:
For Calcium (Ca):
Temperature change (Ca) = Heat / (Mass * Specific heat)
Temperature change (Ca) = Heat / (25.0 g * 0.647 J/g°C)
For Iron (Fe):
Temperature change (Fe) = Heat / (Mass * Specific heat)
Temperature change (Fe) = Heat / (25.0 g * 0.449 J/g°C)
For Silver (Ag):
Temperature change (Ag) = Heat / (Mass * Specific heat)
Temperature change (Ag) = Heat / (25.0 g * 0.235 J/g°C)
For Gold (Au):
Temperature change (Au) = Heat / (Mass * Specific heat)
Temperature change (Au) = Heat / (25.0 g * 0.129 J/g°C)
Since the heat added is the same for all metals, we can compare the temperature changes by looking at the denominator of each formula. The larger the specific heat value, the smaller the temperature change.
Comparing the specific heat values, we can see that Gold (Au) has the largest specific heat of 0.129 J/g°C. Therefore, Gold (Au) will experience the largest temperature change.
So the answer is D) Au.
