Sample Problems and Solutions from the Chemlab 16 Calorimetry Answer Key
Problem 1: Calculating Heat Absorbed by Water
Question: A 50 g sample of water is heated from 20°C to 80°C. What is the amount of heat absorbed?
Solution:
- Identify known values:
- m = 50 g = 0.05 kg
- c = 4186 J/kg·°C (specific heat of water)
- ΔT = 80°C - 20°C = 60°C
- Apply the formula:
Q = mcΔT
- Calculate:
Q = 0.05 kg × 4186 J/kg·°C × 60°C = 12,558 J
Answer: The water absorbs approximately 12,558 Joules of heat.
Problem 2: Determining Enthalpy Change in a Reaction
Question: In a calorimetry experiment, 100 mL of a substance with a density of 1 g/mL is heated, and the temperature increases by 15°C. If the specific heat capacity is 2.0 J/g·°C, what is the enthalpy change?
Solution:
- Calculate the mass:
- Mass = volume × density = 100 mL × 1 g/mL = 100 g
- Use the heat formula:
Q = mcΔT = 100 g × 2.0 J/g·°C × 15°C = 3,000 J
- Interpretation:
- The enthalpy change ΔH ≈ 3,000 J (assuming constant pressure and no heat loss)
