Let's analyze the problem step by step, using the provided data to answer the questions.
1. Identifying the materials and their specific heats:
| Material | Specific Heat [tex]\( ( J / g ^{\circ} C ) \)[/tex] |
|----------|----------------------------------------|
| aluminum | 0.90 |
| iron | 0.44 |
| lead | 0.16 |
| sand | 0.83 |
| steel | 0.49 |
| wood | 1.80 |
| water | 4.18 |
2. Determine the material with the highest specific heat:
Compare the specific heats of each material:
- aluminum: 0.90
- iron: 0.44
- lead: 0.16
- sand: 0.83
- steel: 0.49
- wood: 1.80
- water: 4.18
The highest value is 4.18, which corresponds to water.
Conclusion: The material with the highest specific heat is water.
3. Determine the material with the lowest specific heat:
Compare the specific heats of each material again:
- aluminum: 0.90
- iron: 0.44
- lead: 0.16
- sand: 0.83
- steel: 0.49
- wood: 1.80
- water: 4.18
The lowest value is 0.16, which corresponds to lead.
Conclusion: The material with the lowest specific heat is lead.
4. Determine the material that can absorb twice as much heat as aluminum:
The specific heat of aluminum is 0.90 [tex]\( J / g ^{\circ} C \)[/tex]. To find the material that can absorb twice as much heat, calculate:
[tex]\[
2 \times 0.90 = 1.80
\][/tex]
Now, compare this value to the specific heats of the materials:
- aluminum: 0.90
- iron: 0.44
- lead: 0.16
- sand: 0.83
- steel: 0.49
- wood: 1.80
- water: 4.18
The value 1.80 matches the specific heat of wood.
Conclusion: The material that can absorb twice as much heat as aluminum is wood.
Summary of the results:
- The material with the highest specific heat is water.
- The material with the lowest specific heat is lead.
- The material that can absorb twice as much heat as aluminum is wood.
