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 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
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
Is there a change in an objects thermal energy if the object is at thermal equilibrium?
no
Why is an object warm on a sunny day?
The surface of the Earth is heated by radiation from the sun.
What is the defiition of thermal energy?
when your phone or an object gets heated up or gets hot.
Does the volume of an object change if heated?
The volume of a substance increases when heated
