Based on their given specific heat capacities which compound would show the greatest temperature change upon absorbing 25.0 J of heat? 

• A. 250.0 g Al
• B. 250.0 g Cu
• C. 250.0 g ethanol
• D. 250.0 g wood

Answer: (B)

Verified step by step guidance

1. Identify the formula for calculating the temperature change: \( \Delta T = \frac{q}{m \cdot C} \), where \( q \) is the heat absorbed, \( m \) is the mass, and \( C \) is the specific heat capacity.
2. Substitute the given values into the formula for each substance. For example, for aluminum: \( \Delta T_{Al} = \frac{25.0 \text{ J}}{250.0 \text{ g} \times 0.900 \text{ J/g°C}} \).
3. Repeat the substitution for copper: \( \Delta T_{Cu} = \frac{25.0 \text{ J}}{250.0 \text{ g} \times 0.385 \text{ J/g°C}} \).
4. Repeat the substitution for ethanol: \( \Delta T_{ethanol} = \frac{25.0 \text{ J}}{250.0 \text{ g} \times 2.460 \text{ J/g°C}} \).
5. Repeat the substitution for wood: \( \Delta T_{wood} = \frac{25.0 \text{ J}}{250.0 \text{ g} \times 1.760 \text{ J/g°C}} \). Compare the calculated \( \Delta T \) values to determine which substance has the greatest temperature change.
