What is the similarities and differences between conduction and convection?
Both conduction and convection are types of heat transfer, meaning they move heat from one object to another. The difference is how they transfer the heat. Conduction transfers heat from touching solid to touching solid, while convection transfers heat in fluids (liquid or a gas).Convection transfers heat by having the warm types of fluid rise while the cold sinks. This creates something called a convection current.
What is the flow of thermal energy through a liquid or gas?
Some three types of heat transfers are convection, radiation and conduction.
What is difference between condenser and heat exchanger?
A heat exchanger is a device that transfers heat from one fluid to the others. A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. Majorly condenser is used to cool the required vapor and heat exchanger is used to heat the required liquid.
What are 3 household items that change electrical energy into heat energy?
radiator toaster microwave there's 3 random ones !
What is one type of home heating system and describe how it transfers energy to warm the air inside the rooms?
Heat pumps use the evaporation and condensation of a refrigerant to provide heating in the winter and cooling in the summer. The liquid refrigerant travels through the out door coils during the winter and absorbs enough energy from the outside air to evaporate. Work is done on the gas by a compressor, increasing the refrigerant's energy. Then the refrigerant moves through the coils inside the house. The hot gas transfers heat energy to the air inside the house. This process warms the air while cooling the refrigerant gas enough for it to condense back into a liquid.
What forms when gas or liquid transfers heat as it moves?
steam
What is the term for heat transfers because of the movement of a gas?
convection
Is it true that the flow that transfers heat within a fluid is called a convection current?
In a convection current, heat flows with the heated molecules as they move around in the liquid or gas. In a solid, the heat transfers via condition
What transfers thermal energy by the movement of molecules from one place to another in a gas or liquid?
Heat Conduction.
What is the function of the gas stove?
Rather obvious, to create flames which generate heat, which then transfers that heat to your food so you can eat warm homecooked meals.

How does heat transfer from the stove to the pot?
On an electric stove, the heat coil directly touches the pot, facilitating the conduction or direct heat transfer. On a gas stove, the burning fuel transfers heat to a pot by both radiation and convection.

What do refrigerators use to absorb heat and lower the temperature of the food inside?
FREON. Freon is now illegal because it damages the Earth's ozone layer. The replacement refrigerant is the inert gas tetrafluoroethane commonly called R134a. Also note that the refrigerator does not"absorb" the heat. It is transferred from inside the compartment to outside the compartment. It does this by the use of two heat exchangers. One transfers the heat from the inside to the refrigerant and the second transfers the heat from the refrigerant to the outside.
How is heat transferred to water in a water heater?
In a gas water heater: The gas flame warms the water, exactly the same way as a gas stove burner does for a pan of water on the stove. In an electric water heater, an element - same as an electric range element, but a different shape - heats up from electrical current, and transfers that heat to the water.
Is it more expensive to heat a home with a gas furnace?
No, gas is the best heating fuel if you consider price. The only exeption is, are you building a new structure or changing the heat system in an exsisting structure and have to consider new line overages. New gas service is normally installed by the gas provider at a minimal cost unless the distance from the main is over a certain distance. Call you service provider for this information.
