Where it is used

• Separate condenser — is used in. Watt drew on Black’s research on latent heat.
• Boiler — is used in. Evaporation needs latent heat.
• Vapour-compression cycle — is used in. The evaporation of the refrigerant produces cold.
• Heat pipe — is used in. Evaporation and condensation.
• Ice cream maker — is used in. Ice with salt draws away heat.
• Cloud chamber — is used in. Supersaturated vapour.
