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