Calculating Specific Heat Capacity & Heat Measurement of HCl

Click For Summary
SUMMARY

The specific heat capacity of hydrochloric acid (HCl) can be calculated using the formula \( q = mc\Delta T \), where \( q \) is the heat absorbed or released, \( m \) is the mass of the substance, \( c \) is the specific heat capacity, and \( \Delta T \) is the change in temperature. For a 50 mL sample of HCl with an initial temperature of 20°C and a final temperature of 26°C, the heat measurement is determined to be 1.68 kJ. For a 100 mL sample with an initial temperature of 20°C and a final temperature of 31°C, the heat measurement is 2.52 kJ. The specific heat capacity of HCl is approximately 4.18 J/g°C.

PREREQUISITES
  • Understanding of the specific heat capacity formula
  • Basic knowledge of temperature measurement in Celsius
  • Familiarity with mass and volume conversions
  • Ability to perform calculations involving heat transfer
NEXT STEPS
  • Research the specific heat capacity of other acids for comparison
