Heat Transfer person realize lesson2 chapter 1
To make a complete change in size, shape, color, or other property.
Transform
Energy
All physical processes involve into what?
The transfer of energy from one particle of matter to another within an object or between two objects that are in direct contact.
Conduction
Which method of heat transfer causes ice to from on roads in the winter in cold climates? Explain
Conduction. When liquid water touches a road that is below freezing. Heat from the water moves to the colder road, lowering the temperature on the liquid water.
The transfer of thermal energy by the movement of a fluid.
Convection
In one direction and by three different methods.
Heat doesn't transfer in random directions. How does it travel?
warmer areas to cooler areas by conduction, convection, and radiation.
Heat is transferred from?
from one place to another.
How is conduction, convection, and radiation, energy is transferred?
The transfer of energy by electromagnetic waves.
Radiation
Energy is transferred from one place to another; but the overall amount of energy remains the same.
A student observes that water in a pot on a burner becomes hotter. Explain how energy is conserved in this situation?
The movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to anthor.
Convection current
No. Because it is in law of conservation.
Is there type of energy transfermation in which the system destroys or create energy. Explain
created or destroyed.
The law of conservation of energy, energy cannot be
Warmer areas to colder areas by conduction, convection, and radiation.
What are three ways that heat can be transferred?
wind and changes in the weather.
What does Convection currents in the air cause?
Radition
What type of heat transfer occurs when you roast a marshmallow by holding it over a campfire?
Radiation
Which type of heat transfer can happen through empty space?
Convection current.
Which type of heat transfer creates currents and cannot occur in soilds?
