| Description: Heat energy Measured in calories – one calorie is the heat necessary to raise the temperature of one gram of water one degree Celsius Latent heat Stored or hidden heat Not derived from temperature change Important in atmospheric processes Three states of matter Solid Liquid Gas To change state, heat must be Absorbed, or Released Processes Evaporation Liquid is changed to gas 600 calories per gram of water are added – called latent heat of vaporization Condensation Water vapor (gas) is changed to a liquid Heat energy is released – called latent heat of condensation Processes Melting Solid is changed to a liquid 80 calories per gram of water are added – called latent heat of melting Freezing Liquid is changed to a solid Heat is released – called latent heat of fusion Sublimation Solid is changed directly to a gas (e.g., ice cubes shrinking in a freezer) 680 calories per gram of water are added Deposition Water vapor (gas) changed to a solid (e.g., frost in a freezer compartment) Heat is released Picture Stats: Views: 307 Filesize: 2.22MB Height: 915 Width: 1393 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=39783 |
