SUMMARY

The heat capacity of a liquid can be calculated using the formula \( C = \frac{Q}{m \Delta T} \), where \( C \) is the heat capacity, \( Q \) is the heat added (47.5 J), \( m \) is the mass of the liquid (13.2 g), and \( \Delta T \) is the change in temperature (1.72 °C). By substituting the values into the equation, the heat capacity is determined to be approximately 2.02 J/g°C. This calculation emphasizes the importance of understanding the relationship between heat, mass, and temperature change in thermodynamics.

PREREQUISITES
  • Understanding of basic thermodynamics concepts
  • Familiarity with the formula for heat capacity
  • Knowledge of units of measurement in physics and chemistry
  • Ability to perform basic algebraic calculations
NEXT STEPS
  • Research the concept of specific heat capacity and its applications

Can anyone help me with a chemistry ?

When 47.5 J of heat are added to 13.2 g of a liquid, its temperature raises by 1.72 degree Celsius. What is the heat capacity of the liquid?
 
Physics news on Phys.org


What equations combining amount of heat, amount of substance, heat capacity and temperature change do you know?
 


Look at the units of heat capacity. It's energy divided by mass and temperature. You have 3 numerical values provided in the problem statement. How would you combine them such that you achieve the units of heat capacity? Units tell you what to do.
