Concept explainers
Interpretation: The temperature raised for10.0 g of each sample needs to be determined, if 1.00 kJ of heat is applied.
Concept Introduction: Specific heat capacity can be defined as the heat in joules that is required to raise the temperature of 1 g of substance by 1°C. The relation between specific heat capacity and heat required is shown below:
Answer to Problem 58A
Substance | Temperature change (°C) |
Water | 23.9 |
Ice | 49.3 |
Steam | 50 |
Aluminium | 112 |
Iron | 222 |
Mercury | 714 |
Carbon | 141 |
Silver | 417 |
Gold | 769 |
Copper | 260 |
Explanation of Solution
Heat = 1.00 kJ = 1000 J
Mass = 10.0 g
- Specific heat capacity for water = 4.184 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for ice = 2.03 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for steam = 2 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for Aluminium = 0.89 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for iron = 0.45 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for liquid mercury = 0.14 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for carbon = 0.71 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for Silver = 0.24 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for Gold = 0.13 J/g°C Substitute the values to calculate temperature change:
- Specific heat capacity for copper = 0.385 J/g°C Substitute the values to calculate temperature change:
Thus,
Substance | Temperature change (°C) |
Water | 23.9 |
Ice | 49.3 |
Steam | 50 |
Aluminium | 112 |
Iron | 222 |
Mercury | 714 |
Carbon | 141 |
Silver | 417 |
Gold | 769 |
Copper | 260 |
