What causes the stopper to pop out? Upon heating, the volume of the gas inside the bottle increases and pushes the stopper to pop outside. Upon heating, the particles of the gas move slower and the volume of the gas decreases and pushes the stopper to pop outside. Upon heating, the volume of the gas inside the bottle decreases 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. 3 / 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 volume will increase the ball's volume will decrease the ball's mass will decrease 4 / 20 Evaporation is _______________ . the process of a gas change to liquid. a new type of car built for 2018. process of a liquid freezing. the process of a liquid change to gas. 5 / 20 As the temperature of a sample goes up, the __________ energy of the particles in that sample is increasing kinetic potential chemical electrical 6 / 20 The temperature at which a liquid becomes a gas is called ______________________? Boiling point Freezing point Melting point Condensation point 7 / 20 What happens to the molecules of a substance as it gets cooler? The molecules expand The molecules shrink The molecules move faster The molecules move slower 8 / 20 In an open system, ________________. kinetic energy and temperature of the particles decrease kinetic energy and thermal energy of the particles decrease energy and matter can move between the system and the environment energy and matter cannot move between the system and the environment 9 / 20 What changes occur when the ice cream melts from a solid to a liquid state? the spaces between the particles decrease the kinetic energy of particles decreases the thermal energy of the particles increases the kinetic energy of particles increases 10 / 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 force of the collision of gas particles. The gas pressure is due to the mass of the gas particles. 11 / 20 Which statement best describes Charles's law? At constant temperature, the volume of a gas increases as the pressure increases. 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 decreases as the pressure increases. 12 / 20 As an object is cooled what is happening to the Thermal Energy? It remains the same It is taken away from the object It is adding to the object 13 / 20 What are three states of matter? Solids, Liquid, and Gases Physical and Chemical Changes Hard, soft, and slim 14 / 20 How could you heat an object? Keep the object at a constant temperature. Place the object next to another warmer object. Place the object next to another colder object. Decrease the temperature of the object. 15 / 20 During thermal contraction, _____________. the number of particles in the material decreases the spaces between the particles of a material decrease the size of the particles in the material decreases the number of particles in the material increases 16 / 20 Which would BEST describe the process of drops forming on the outside of a water bottle? Condensation Evaporation Freezing 17 / 20 Which definition describes particles in a solid Particles moving over each other Particles completely still Particles vibrating in one place Particles moving around quickly 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 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 increase 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 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 20 / 20 Which statement is TRUE about thermal energy? Thermal energy is the force applied per unit area of surface. Thermal energy is the transfer of kinetic energy from one object to another. Thermal energy is the total kinetic and potential energy of all the particles. Thermal energy is a measure of the average kinetic energy of the particles of a substance.
