The molecules move faster The molecules expand The molecules shrink The molecules move slower 2 / 24 Which statement is TRUE about thermal energy? Thermal energy is the transfer of kinetic energy from one object to another. 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 force applied per unit area of surface. 3 / 24 As the temperature of a sample goes up, the __________ energy of the particles in that sample is increasing electrical chemical kinetic potential 4 / 24 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. 5 / 24 The relationship of which two variables are compared in Boyle's Law? volume & moles (amount of gas) temperature & pressure volume & temperature pressure & volume 6 / 24 Indicate the variables studied in this case and describe their relationship. Volume and pressure; proportional relationship Volume and temperature; proportional relationship Volume and pressure; inversely proportional relationship Volume and temperature; inversely proportional relationship 7 / 24 When two variables change in opposite ways , they have a(n) ________________ relationship. proportional equally independent inversely proportional 8 / 24 The relationship of which two variables are compared in Charles’s Law? temperature & pressure volume & temperature volume & moles (amount of gas) pressure & volume 9 / 24 What changes will happen to the gas in the syringe if you push the piston as shown in the image? Volume increases Collision between particles decrease Volume decreases Pressure increases 10 / 24 What remains constant according to Charles’ Law? Temperature Length Pressure Volume 11 / 24 According to Charles Law, if Temperature of a gas increases Volume will also.... Decreases Increases Stays the same 12 / 24 What factors could increase the pressure of a gas inside a container? decreasing the volume increasing the number of particles decreasing the number of particles increasing the volume 13 / 24 Which container will have a lower pressure? B They both have the same pressure A I don't know 14 / 24 Boyle’s Law describes the inverse relationship between pressure and volume. Which statement BEST describes this relationship between pressure and volume? When volume increases, pressure decreases. When volume decreases, pressure remains constant. When volume decreases, pressure decreases. When volume increases, pressure increases. 15 / 24 Boyle's law studies the relationship between _______________. volume and number of particles pressure and volume pressure and number of particles pressure and temperature 16 / 24 Where do you think boiling water is faster: on the mountaintop or on the sea surface? can't be determined on the mountaintop on the sea surface the same on both 17 / 24 ____________ is the force applied per unit area of a material's surface. Pressure Volume Temperature Heat 18 / 24 Which of the following quantities are kept constant in Boyle’s law? pressure of gas and temperature number of gas particles and pressure heat and temperature number of gas particles and temperature 19 / 24 Boyle’s Law describes the inverse relationship between pressure and volume. Which statement BEST describes this relationship between pressure and volume? When volume decreases, pressure remains constant. When volume increases, pressure decreases. When volume decreases, pressure decreases. When volume increases, pressure increases. 20 / 24 At constant temperature, the relationship between the pressure and the volume of a fixed amount of gas is described __________. by Boyle's law by Faraday's Law by Newton's law by Charles's law 21 / 24 What is the effect of pumping more gas particles into a solid container? gas pressure inside the container increases then decreases gas pressure inside the container decreases gas pressure inside the container increases gas pressure inside the container remains constant 22 / 24 Observe the graph that shows the relationship between two variables. Indicate the variables studied in this case and describe their relationship. volume and pressure; inversely proportional relationship volume and pressure; proportional relationship volume and temperature; inversely proportional relationship volume and temperature; proportional relationship 23 / 24 Which of the following graphs shows an inverse relationship between its variables? . . . . 24 / 24 State Boyle’s law gas particles are far apart boiling is controlled by volume volume is inversely proportional with pressure pressure of gas is always high Your score is 0% Restart quiz Go to the Quizzes Page
