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