Melting point Condensation point Freezing point Boiling point 2 / 20 Evaporation is _______________ . the process of a liquid change to gas. a new type of car built for 2018. the process of a gas change to liquid. process of a liquid freezing. 3 / 20 During thermal contraction, _____________. the number of particles in the material increases the size of the particles in the material decreases the number of particles in the material decreases the spaces between the particles of a material decrease 4 / 20 How does heat flow? from hotter objects to colder objects in both directions (hot to cold AND cold to hot) from colder objects to hotter objects 5 / 20 Which statement best describes Charles's law? At constant pressure, the volume of a gas increases as the temperature increases. At constant pressure, the volume of a gas decreases as the temperature increases. At constant temperature, the volume of a gas increases as the pressure increases. At constant temperature, the volume of a gas decreases as the pressure increases. 6 / 20 In an open system, ________________. energy and matter can move between the system and the environment energy and matter cannot move between the system and the environment kinetic energy and thermal energy of the particles decrease kinetic energy and temperature of the particles decrease 7 / 20 What changes occur when the ice cream melts from a solid to a liquid state? the kinetic energy of particles increases the spaces between the particles decrease the thermal energy of the particles increases the kinetic energy of particles decreases 8 / 20 How could you heat an object? Place the object next to another colder object. Decrease the temperature of the object. Keep the object at a constant temperature. Place the object next to another warmer object. 9 / 20 The temperature at which a solid turns into a liquid... particle accelerator thermometer data point melting number melting point 10 / 20 What do you expect will happen to a ball if the boy puts the ball in a refrigerator? the ball's mass will increase the ball's mass will decrease the ball's volume will increase the ball's volume will decrease 11 / 20 Which would BEST describe the process of drops forming on the outside of a water bottle? Freezing Evaporation Condensation 12 / 20 Which statement is TRUE about thermal energy? Thermal energy is a measure of the average kinetic energy of the particles of a substance. Thermal energy is the total kinetic and potential energy of all the particles. Thermal energy is the transfer of kinetic energy from one object to another. Thermal energy is the force applied per unit area of surface. 13 / 20 As an object is cooled what is happening to the Thermal Energy? It is taken away from the object It remains the same It is adding to the object 14 / 20 Which definition describes particles in a solid Particles vibrating in one place Particles moving over each other Particles completely still Particles moving around quickly 15 / 20 What are three states of matter? Physical and Chemical Changes Solids, Liquid, and Gases Hard, soft, and slim 16 / 20 A perfume bottle is left outside on the floor on a hot day, the stopper pops out of the bottle. What causes the stopper to pop out? Upon heating, the volume of the gas inside the bottle decreases and pushes the stopper to pop outside. Upon heating, the volume of the gas inside the bottle increases and pushes the stopper to pop outside. Upon heating, the difference in temperature between the inside and the outside of the bottle pops the stopper outside. Upon heating, the particles of the gas move slower and the volume of the gas decreases and pushes the stopper to pop outside. 17 / 20 What happens to the molecules of a substance as it gets cooler? The molecules move slower The molecules expand The molecules shrink The molecules move faster 18 / 20 Some glass cups are stuck in each other. How could you separate the cups without losing any one of them? Pour very cold water into the upper cup which walls will contract and increase in volume slightly. So it can be removed from others. Pour very hot water into the upper cup which walls will contract and increase in volume slightly. So it can be removed from others. Pour very cold water into the upper cup which walls will contract and decrease in volume slightly. So it can be removed from others. Pour very hot water into the upper cup which walls will contract and decrease in volume slightly. So it can be removed from others. 19 / 20 The gas enclosed in a container exerts a pressure on the inner walls of the container. What is the cause of the gas pressure? The gas pressure is due to the size of the gas particles. The gas pressure is due to the spaces between the gas particles The gas pressure is due to the mass of the gas particles. The gas pressure is due to the force of the collision of gas particles. 20 / 20 As the temperature of a sample goes up, the __________ energy of the particles in that sample is increasing chemical kinetic potential electrical Your score is 0% Restart quiz Go to the Quizzes Page
