Answer 13

temperature when the saturated vapor pressure of a liquid is equal the atnospheric pressure

Question 14

When can water remain at liquid stage?

Question 17

What is conduction?

Answer 17

Transfer of heat energy through matter by internal molecular motion

Question 18

What is convection?

Answer 18

transfer through movement of a heated gas or liquid

Question 22

What is aborbtion when light is transmitted through water?

Answer 22

taking in of a substance by chemical or molecular means, change light or sound into another form of energy (usually heat).

Question 23

What is scatter when light is transmitted through water?

Answer 23

random redirection of light or sound energy by reflection on uneven boundary.

Question 24

What is refraction when light is transmitted through water?

Answer 24

change in direction of a light or sound wave due to a change in the substance it is moving through.
