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