Sagot :
To determine which substance would heat up the slowest, we need to look at the specific heat values provided. The specific heat is a measure of how much heat energy is required to raise the temperature of a given amount of a substance by a certain amount. A higher specific heat means that the substance requires more energy to heat up, and therefore, it will heat up more slowly compared to substances with lower specific heat values.
The specific heat values provided are as follows:
- Brick: [tex]\(0.9 \, \frac{\text{J}}{\text{g} \cdot \text{°C}}\)[/tex]
- Dry Soil: [tex]\(1.26 \, \frac{\text{J}}{\text{g} \cdot \text{°C}}\)[/tex]
- Paper: [tex]\(1.396 \, \frac{\text{J}}{\text{g} \cdot \text{°C}}\)[/tex]
- Water: [tex]\(4.18 \, \frac{\text{J}}{\text{g} \cdot \text{°C}}\)[/tex]
To find out which substance heats up the slowest, we should compare these specific heat values. The substance with the highest specific heat value will heat up the slowest because it requires the most energy to increase its temperature by one degree Celsius.
Comparing the given values:
- Brick: 0.9
- Dry Soil: 1.26
- Paper: 1.396
- Water: 4.18
We can see that water has the highest specific heat value of 4.18.
Therefore, the correct answer is:
a. water
