calorimetry

experimental method for finding enthalpy change by measuring temperature change over time

-data can be extrapolated on graph to give accurate value for change in temperature

2
New cards

measured change in temperature is proportional

to energy change

3
New cards

q (energy change)

mass x specific heat capacity x temperature change

4
New cards

specific heat capacity

energy required to raise 1g of substance by 1K without a change in state

5
New cards

enthalpy change per mole =

energy change / moles

6
New cards

enthalpy change values are never accurate as

  • energy easily lost from a system through conduction or convections

  • inaccuracies in measuring temperatures
