How does double glazing the windows keep the house warm? What mode(s) of heat transfer is blocked by double glazing?
How can a home be made warm in winter? Identify the mode of heat transfer each method uses to keep the house warm.
On which side will your hand feel hotter: above (but not touching) the flame or below it? Why?
Explain why the igloo can keep the Eskimo warm even if it is made of ice.
A newspaper wrapping keep hot things hot and cold things cold. Why? What other wrappings can be used that works like a newspaper?
What is the advantage(s) of placing the electric heater near the bottom of a bucket of water compared to putting it near the surface? What is the disadvantage(s)?
Why do we have sea breeze in the morning and land breeze at night?
1 1 Convection When you boil water the lower water layer heats up quickly then it goes up and the upper water layer ( cold ) goes down. This process takes.
1 FEROSKHAN M. 2 Objectives: Understanding modes of Heat Transfer. Applications of heat transfer in everyday phenomena.
Topic 6 – Transferring Energy
Coastal Breezes At the seaside we often find that the wind is blowing. Sometimes it blows in from the sea and at other times it blows out to sea. Can the.
Convection Convection is the transfer of heat by the circulation of currents from a hotter to cooler region. Convection currents only occur in liquids.
Heat Transfer Conduction, Convection, and Radiation.
10 Energy Saving Advices. 1- Lowering of the temperature at night Limit the lowering of the temperature at night. If the temperature is reduced too much,
Sea Breeze and Land Breeze. What do we remember about Specific Heat? Substances with a high specific heat warm and cool slowly. They take more energy.
Conduction and Convection. What happens when cold (coloured) water is poured into hot clear water? A current will be created. Why is a current created?
Transfer of Energy
Sea Breeze When you walk on the beach during the daytime, what does it feel like? Warm or Cold? What about the water?
Transfer of Energy Energy Transfer Energy is transferred from hotter object to colder object Examples? –Cooking pasta –Making ice –Making popcorn –Roasting.
Wind: Sea Breeze and Land Breeze. EnergyTransfer in the Atmosphere Energy moves through the atmosphere in three different ways-conduction, convection.
