![**Question:**
1. How much heat is required to raise the temperature of 53 g of each of the following substances by 23 K?
- **Substance A** (\(C_A = 8.37 \, \text{J/g-K}\))
- **Substance B** (\(C_B = 0.945 \, \text{J/g-K}\))
- **Substance C** (\(C_C = 0.0567 \, \text{J/g-K}\))
**Explanation:**
This problem requires calculation of the heat needed to increase the temperature of 53 grams of three different substances, each with a unique specific heat capacity, by 23 Kelvin (\(K\)).
The formula to determine the heat required (\(q\)) is:
\[ q = m \cdot C \cdot \Delta T \]
where:
- \(q\) = heat energy (in Joules, \(J\))
- \(m\) = mass (in grams, \(g\))
- \(C\) = specific heat capacity (in \(\text{J/g-K}\))
- \(\Delta T\) = change in temperature (in Kelvin, \(K\))
**Details:**
1. **Substance A**
- Specific heat capacity: \(8.37 \, \text{J/g-K}\)
2. **Substance B**
- Specific heat capacity: \(0.945 \, \text{J/g-K}\)
3. **Substance C**
- Specific heat capacity: \(0.0567 \, \text{J/g-K}\)
