Which of the following accurately describes the effects of temperature changes on solids? a. if the temperature of a solid is decreased, the solid expands and its volume decreases. b. if the temperature of a solid is decreased, the solid contracts and its volume increases. c. if the temperature of a solid is increased, the solid expands and its volume increases. d. if the temperature of a solid is increased, the solid contracts and its volume increases.

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

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

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?
