When cleaning up a local beach, students found many different particles that were in the water that affected the shoreline, like litter and gasoline. which of the following describe how these items would need to separated from the water? why? a. both gasoline and litter would need to be chemically separated from the water, because both form new bonds with the water. b. litter would need to be physically separated with water and gasoline would need to be chemically separated from water, because both form a mixture with the water. c. both gasoline and litter would need to be chemically separated from the water, because neither bonds with the water. d. both gasoline and litter would need to be physically separated from the water, because neither bonds with the water. (p. s. do teachers know about this? like fr)

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

A4.0-cm tall light bulb is placed a distance of 32.0 cm from a concave mirror having a focal length of 16.0 cm. determine the image distance
