Open the PhET States of Matter Simulation (http://openstaxcollege.org/l/16phetvisual) to answer the following questions:
(a) Select the
(b) For each substance, select each of the states and record the given temperatures. How do the given temperatures for each state correlate with the strengths of their intermolecular attractions? Explain.
(c) Select the Interaction Potential tab, and use the default neon atoms. Move the Ne atom on the right and observe how the potential energy changes. Select the Total Force button, and move the Ne atom as before. When is the total force on each atom attractive and large enough to matter’? Then select the Component Forces button, and move the Ne atom. When do the attractive (van der Waals) and repulsive (electron overlap) forces balance? How does this relate to the potential energy versus the distance between atoms graph? Explain.

- name: Solids and liquids Read the questions, then show your answers by filing in the circle beside the correct response. Then, colour the picture based on the instructions provided. Background: Colour the spaces with solids Yellow Colour the spaces with liquids Orange Questions: 1. When does water change from liquid to solid? o When the temperature drops below zero degrees Celsius : Light Blue (colour the 1's light blue) o When the temperature rises above 100 degrees Celsius: purple (colour the 1's purple) 2. When a liquid is poured into a different container it: o Becomes a solid (colour the 2's red) o Remains a liquid (colour the 2's dark blue) 3. A solid can become a liquid if it: o breaks apart (colour the 3's black) o 'melts (colour the 3's dark Green) 4. This symbol means o Poison (colour the 4's light green) o Explosive (colour the 4's pink)arrow_forwardWhat is formed when gas is enclosed in a chamber then liquified under very high pressure? * What latent heat value signifies the lost of heat during a phase change? What is the unique temperature and pressure at which the three phases of a substance are in equilibrium with each other? * Which liquid crystal is of pharmaceutical significance? *arrow_forwardA white substance melts at 70 degrees Celsius. As a solid or in aqueous form it does not conduct electricity and can be easily crushed . What type of solid is this substance likely to be ? Justify your answer .arrow_forward
- When a substance is turning from a solid into a liquid, there is no rise in temperature. All the energy input into the substance is being used to transform the state of matter. A) true B) falsearrow_forwardDefine the phases of matter and phase change?arrow_forward1.Can the states of matter change from one form to another (ex solid to liquid)? Yes or No? How? 2.What do you call the change in the state of matter? 3.What are the processes involved in phase change?arrow_forward
- Given the picture below. Answer the following questions. 1. What determines the state of a material? How do you know whether a material is solid, liquid or gas? 2. What accounts for the similarities in all three materials?arrow_forwardAs a substance is subjected to pressure and/or temperature changes, it may undergo condensation, deposition, freezing, melting, sublimation, or vaporization. (a) Consider the phase diagram shown below and state the cha nges that take place upon going from points A to B to C to D. (b) Is the transition from C to D exothermic or endothermic?arrow_forwardAre the melting temperature and freezing temperature the same for a pure substance? Why is that?arrow_forward

Sketch…arrow_forwardThink about what you already know about different phases of matter. Given this figure showing the process of changing from one phase to another, what parameter (physical quantity of a system) serves as an indicator for energy flowing into or out of the molecular system? Gas Cool or compress Heat or reduce pressure Liquid Cool Heat Crystalline solid In the box below, make a claim as to which parameter is represented in the processes in the figure and use your ideas of energy to support your claim.arrow_forwardIn our previous discussions, we discussed how phase changes (gas to liquid to solid, for example) can occur by manipulating the parameter of temperature. We defined temperature as the average kinetic energy of the particles, so when we raise or lower the temperature, we are adding or removing energy to the system, respectively. Gas Cool or compress Heat or reduce pressure Liquid Cool Heat Crystalline solid Based on your observations over the past two weeks, please explain why lowering the temperature can condense the helium gas into a liquid, a process by which the He atoms stick together?arrow_forward
