Energy is usually transferred in fluids by radiation true or false?
Oh, dude, false! Energy in fluids is mostly transferred through convection, where the hot fluid rises and the cooler fluid sinks. Radiation is more like when the sun heats up your face at the beach, not so much what's going on in your morning coffee. So, yeah, it's all about that convection, not the radiation.
What are some advantages and disadvantages of thermal energy?
There are two main types of thermal energy - solar and geothermal. Solar energy is renewable and sustainable, and after the initial investment, is free. Geothermal energy is renewable, sustainable, and clean reducing reliance on foreign energy sources. The disadvantages are mostly financial because of the start up costs. While solar is an individual form of energy, geothermal requires large generation plants. Also solar viability is dependent on the amount of sunshine the area receives.
What is released during every energy transformation?
Energy is neither created nor destroyed; the total energy remains the same(1st law of thermodynamics). Also, theoretically the maximum efficiency of a thermodynamic reaction is 100%- but in reality a portion of the input energy is transformed into other forms like heat, sound, light or a change in the internal order of the system. Therefore energy is not lost in a closed system just transformed into many different types of energy.
What is the method by which heat is transferred into in a fluid liquid or gas?
Transfer of heat in nature occurs through three ways: conduction, convection and radiation. Conduction takes place in solids. Convection in liquids and gases. Radiation takes place in all three media as well as in vaccum.
Compare and contrast convection and conduction?
convection means when something is heated it expands or conducts eg. metal is heated it contracts when it is cooled it contracts.
Which type thermal energy transfer occurs mostly in fluids?
Convection
What type of thermal energy transfers occurs mostly in fluids?
Convection is the primary method of thermal energy transfer in fluids. This process involves the transfer of heat through the physical movement of fluid particles, such as in the circulation of hot air rising and cool air sinking.
Which type of thermal energy transfer occurs mostly in fluids?
Convection is the primary mode of thermal energy transfer that occurs in fluids. In convection, heat is transferred through the movement of the fluid itself, either by natural (due to density differences) or forced (due to external energy input) convection.
What type of energy transfer occurs mostly in fluids?
convection
Transfer of thermal energy through atoms contacting other atoms?
Not likely. Atoms are mostly empty space.
What types of thermal energy are responsible for tranferring heat from oven to brownies?
In a conventional oven it's mostly conduction,with a bit of air convection thrown in.There are "ovens" (as seen on TV ... mostly at 3AM) that use hot air and forced convection as the main heat transfer technique.
What is the thermal energy of particles in a substance?
Mostly the kinetic energy of particles due to heating is called thermal energy Temperature is a measure of heat
What is the not good material at conducting thermal energy?
One material that is not good at conducting thermal energy is styrofoam. Styrofoam is a poor conductor because it has a low density and is composed mostly of pockets of air, which hinders the transfer of heat. This property makes styrofoam useful for insulation purposes.
Combustion potential chemical energy is transformed mostly into?
When chemical energy is converted into thermal energy during combustion, it is transformed mostly into heat and light energy. This process releases energy in the form of heat and emits light, resulting in a visible flame.
How is thermal energy transferred around our Earth?
Mostly by wind and current.
Can an object have heat and thermal energy?
The answer is "partly". Thermal energy consists of the average kinetic energy of the particles (how much they move around, bumping into things and each other) and the average potential energy of the particles (tough to picture - how much they "shake back and forth", or oscillate, from their normal, resting position).
Which method of energy transfer mostly involved in weather?
Convection.
