- Q1Why is condensing water vapor to form liquid water considered a physical change?The water changes its identityThe ice has some new propertiesThe vapor floats above the liquid waterThe water changes its state30sSPS5a
- Q2In order for liquid methanol to form gas and enter the air, what must happen to the methanol?It must undergo an exothermic changeIt must increase its presssureIt needs to condenseIt needs to gain energy30sSPS5a
- Q3Which of the following would happen at a lower temperature?Particles in an object have more energyGas particles bump into walls more oftenGas expandsParticles in an object move slower30sSPS5a
- Q4Which of the following happens to the particles when a solid becomes a liquid?The pack closer togetherThey spread apart from one anotherThey create energyThey move less30sSPS5a
- Q5What is the reverse phase change of melting?SublimationVaporizationFreezingFusion30sSPS5a
- Q6Mr. Spitler accidentally drops his favorite pen in a beaker of water. The pen has a mass of 25 g and the water level in the beaker rises from 175 mL to 198 mL. Determine the density of Mr. Spitler's pen.0.92 mL/g1.09 g/mL0.92g/mL7.92 g/mL120sSPS5a

- Q8Which of the following best describes the motion of particles in a solid?They vibrate and rotate in placeThe move independently of one anotherThey slide past one anotherThey are able to overcome attraction and move freely30sSPS5a
- Q9Which of the following statements is NOT true?In all states of matter, particles move at the same speedEvery state of matter is made up of particlesAll particles are made up of atoms and moleculesIn all states of matter the particles are moving30sSPS5a
- Q10Which of the following statements describes a soccer ball under high pressure (fully inflated) compared to a soccer ball under low pressure (deflated)?In a fully inflated soccer ball the particles of gas have less energyIn a fully inflated soccer ball the particles of gas only collide with one anotherIn a fully inflated soccer ball the force exerted on the inside if the ball is lowerIn the fully inflated soccer ball there are more particles of gas45sSPS5a
- Q11Which of the following examples is endothermic?A pond freezing in the winter timeWater boiling in a large potGas particles condensing on a cold drinkAir in a bike tire gaining pressure on a hot day45s
