Challenge Problems
Push your limits with challenges.
Question 1
If 250 mL of water at 20 °C absorbs 1250 J of heat, what is the final temperature assuming the specific heat capacity of water is 4.18 J/(g·°C)?
💡 Hint: Use q = mcΔT, remember to convert mL of water to grams, since they are equal for water.
Question 2
You burn a fuel in a bomb calorimeter that raises the water temperature from 25 °C to 35 °C in a calorimeter with a heat capacity of 5000 J/°C. How much heat was produced?
💡 Hint: Calculate the temperature change before substituting into the equation.
