Air at 3 104 kg/s and 27 c enters a rectangular duct that is 1m long and 4mm 16 mm on a side. a uniform heat flux of 600 w/m2 is imposed on the duct surface. what is the temperature of the air and of the duct surface at the outlet?

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

Drag each item into the proper state of matter category.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
