Question

question 17 (multiple choice worth 3 points) (06.03r mc) why can the sun transmit heat to earth only by radiation? radiation transmits heat through the motion of a gas. the space between the sun and earth contains almost no matter. radiation does not require the creation of electromagnetic waves. the molecules in the sun are moving too fast to cause conduction.

Explanation:

Heat transfer occurs via conduction, convection, and radiation. Conduction and convection require a medium (solid, liquid, or gas). The space between the sun and Earth is a near - vacuum with almost no matter. Radiation is the only heat - transfer method that can occur in a vacuum as it involves the emission of electromagnetic waves.

Answer:

The space between the sun and Earth contains almost no matter.
