Correct Answer: TRUE
Correct Answer: Air Pressure
Explanation:
The temperature at which water boils depends mainly on air pressure.
Correct Answer: Circular motion of electrons
Explanation:
Magnetism in materials is due to circular motion of electrons.
Correct Answer: cold, dense ocean water sinking and warmer water replacing it
Correct Answer: convection
Explanation:
Convection is by far the most efficient and common way for heat to be transferred through liquids and gases. It occurs when some regions of a fluid get hotter than others, causing currents in the fluid that move it around to distribute that heat more evenly.
Correct Answer: Gamma rays
Explanation:
Gamma rays has the shortest wavelength and radio waves has the longest wavelength.
Correct Answer: energy cannot be created or destroyed but can be converted from one form to another
Explanation:
"Conservation of energy" refers to the fact that energy cannot be created or destroyed but can be converted from one form to another.
Correct Answer: Temperature
Explanation:
The primary agent of contact metamorphism is heat or temperature.
Correct Answer: Electric field
Correct Answer: pitch circle diameter
Explanation:
The size of gear is usually specified by pitch circle diameter.
