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