Question 1

What will Happen to an Object as it Absorbs Thermal Radiation?

Answer 1

It will Become Hotter.

Question 2

What Happens to an Object as it Becomes Hotter?

Answer 2

It will Emit More Thermal Radiation.

Question 3

Eventually, an Object will Reach a Point of Constant Temperature. What does this Mean?

Answer 3

It Means that the Object is Absorbing Radiation at the Same Rate at which it is Emitting Radiation.

Question 4

When is an Object in ‘Temperature Equilibrium’?

Answer 4

When it has Reached Constant Temperature; when it Absorbs Radiation at the Same Rate at which it Emits Radiation.

Question 5

When does the Temperature of a Body Increase?

Answer 5

The Temperature of a Body Increases when the Body Absorbs Radiation Faster than it Emits Radiation.
