Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant? 1. The relationship is inversely proportional; as temperature increases, volume decreases in the same way.

2. The relationship is directly proportional; as temperature increases, volume increases in the same way.

3. The relationship is inversely proportional; as temperature increases, volume increases in the same way.

4. The relationship is directly proportional; as temperature increases, volume decreases in the same way.

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

Which compound is held together by the electrostatic force between two ions? a. co2 b. cci4 c. h2s d. mgf2

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
