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