    • ‘He gave explanations of the nature of free heat and latent heat.’
    • ‘Energy is required to provide the latent heat of evaporation for the phase change from liquid to gas (water vapour), which takes place in the cavity below the stomata.’
    • ‘Conversely, when a gas condenses, it must release this latent heat and become a liquid before it can cool below its boiling temperature.’
    • ‘Surface warming leads to cumulus convection and release of latent heat, producing warm temperatures throughout the troposphere.’
    • ‘The theory of latent heat was used by Watt to successfully develop the separate condenser.’
