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