How the thermal energy of an object changes when the objects temperature changes?
when abody is heated definitely its thermal energy increases so far that it can even cause a change in its physical appearance
Do all objects give off thermal radiation?
yes every object gives out thermal radiation
When an object is heated it increases What is this called?
thermal expansion
how is heat transmitted by radiation?
Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .
How hot is infrared radiation?
Infrared radiation is sometimes referred to as thermal radiation. The temperature of infrared radiation varies from object to object. All objects radiate infrared, even objects at room temperature and frozen objects.
How does thermal radiation that is emitted from an object vary?
it changes coulor

What causes thermal expansion of an object when its heated?
Kinetic Energy will [always] do this.
When something is heated does the thermal energy go from the cooler to the warmer object or from a warmer object to a cooler object?
hot to cold
What is the defiition of thermal energy?
when your phone or an object gets heated up or gets hot.
Why is an object warm on a sunny day?
The surface of the Earth is heated by radiation from the sun.
Why do materials expand once heated?
This is called thermal expansion. When an object is heated, it's particles move faster. This causes greater separation between the particles and the object expands. The coefficient of thermal expansion describes how much an object will expand per degree with the same applied pressure.
How hot is infrared radiation?
Infrared radiation is sometimes referred to as thermal radiation. The temperature of infrared radiation varies from object to object. All objects radiate infrared, even objects at room temperature and frozen objects.
What is heated by radiation?
Radiation is a method of heat transfer that does not rely on any contact between the heat source and the heated object (as is the case with convection and conduction) Examples of radiation is heat from the sun or from the fliament of a light bulb
