Energy by Chris Woodford. Dorling Kindersley, 2007. My own book about energy includes a short section on heat energy. Suitable for ages 9–12. An object's temperature doesn't tell us how much heat energy it has. It's easy to see why not if you think about an iceberg and an ice cube. Both are at more or less the same temperature but because the iceberg has far more mass than the ice cube, it contains billions more molecules and a great deal more heat energy. An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger. Aloo Gobi. A fragrant and tasty side with your curry, Aloo Gobi is made up of cauliflower and potatoes in a curry sauce. Tasty and filling, it’s a very popular side for vegetarians. No matter the type of curry you’re enjoying this side is a winner.

Despite the odds the scheme was ready to go online just prior to the ERP becoming operational with the first house in Leslie Road being heated during November 1998. Being able to send its waste heat to a network helps its efficiency andimproves its environmental credentials. An energy plant producing electricity was looked at but government subsidies for this technology were not available to Shetland at the time.Corrosion within the radiator can lead to the formation of rust and sludge, which can obstruct the flow of water and reduce the radiator's heating efficiency. In severe cases, rust can even lead to leaks, causing further damage to the heating system. No customers were guaranteed, even from the SIC, so all customers had to be won in a competitive market. Chart: Everyday materials have very different specific heat capacities. Metals (blue) have low specific heat capacities: they conduct heat well and store it badly, so they feel cold to the touch. Ceramic/mineral materials (orange) have higher specific heat capacitors: they don't conduct heat as well as metals, store it better, and feel slightly warmer when you touch them. Organic insulating materials (green), such as wood and leather, conduct heat very poorly and store it well, so they feel warm to the touch. With very high specific heat capacity, water (yellow) is in a class of its own.

Today’s most efficient way of illuminating and lighting is undoubtedly LED. When compared with older lighting technologies such as Incandescent, Halogen and CFL bulbs, you will find that LED is by far the most energy saving and smart solution. Choose a cold-loving variety of spinach to ensure successful growth. Keep sowing batches throughout the winter, and you’ll have a constant supply across the cold months.

Latent heat

This gives an emissions factor of 0.0567 kg CO2 per kWh. The standard grid electricity emissions factor is 0.136 kg CO2 per kWh. Mr Leask said such efficiency stood the incinerator in good stead for a good future – and was likely to remain online long after others had been shut down. Place the bottles on shelves and walls. The paint will soak up the heat in the day, ready to be released during the night. This is a great, cheap way to keep the heat in. If your symptoms are severe or treatment is not helping, a GP may refer you to a skin specialist (dermatologist). A recent report by Zero Waste Scotland showed the ERP was the most efficient incinerator in Scotland.
