Calorimetry [IB Physics SL/HL]

This video explores calorimetry, defining specific heat capacity (c) as the energy needed to change the temperature of 1 kg of material by 1 degree Celsius or Kelvin (Q=mcΔT), and specific latent heat (L) as the energy required for a phase change of 1 kg of material at its melting or boiling point (Q=mL). It interprets heating curves, explaining how sloping regions relate to specific heat capacity and flat regions to specific latent heat, noting that specific latent heat of vaporization is greater than fusion. The video then discusses thermal energy transfer between objects at different temperatures, emphasizing the conservation of energy, and works through sample problems to demonstrate calculating the rate of energy transfer and the final temperature of a mixture.
