Which explains how the ocean warms the air? a. the seawater absorbs heat from the sun and warms the air above it by convection. b. the seawater absorbs heat from the sun and warms the air above it by conduction. c. the seawater absorbs heat from the sun and warms the air above it by radiation. d. the seawater absorbs heat from the sun and warms the air above it by insulation.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

How is zig zagging a form of acceleration?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
