Draw molecular-level views that show the differences among solids, liquids, and gases.
Which characteristics of a solid, a liquid, and a gas are exhibited by each of the following substances? How would you classify each substance? a. a bowl of pudding b. a bucketful of sand
Open the PhET States of Matter Simulation (http://openstaxcollege.org/l/16phetvisual) to answer the following questions: (a) Select the Solid, Liquid, Gas tab. Explore by selecting different substances, heating and cooling the systems, and changing the state. What similarities do you notice between the four substances for each phase (solid, liquid, gas)? What differences do you notice? (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.
A representation of liquid water is shown below. Which of the three representations that follow best describes the water after it has boiled into steam?
How much ice (in grams) at 0∘C would have to melt to lower the temperature of 352 mLmL of water from 26 ∘C to 6 ∘C? (Assume the density of water is 1.0 g/mLg/mL.) Express your answer using two significant figures.
1. a man who is 5ft 10in. talll weighs 160lb. What is his heightbin centimeter and his mass in kilograms. 2. determine the boiling point of water at 672mmHg 3. a pipet delivers 9.98g of water at 19 degree celsius. what volume does the pipet deliver 4. a 141mg sample was placed on a watch glass that hass a mass of 9.203g. what is the mass of the watch glass and sample in grams
Chlorine trifluoride (ClF3) melts at -76.3 °C and boils at 11.8 °C at a constant pressure of 1 atm. What state of matter must a sample of chlorine trifluoride be in at 20°C and 1 atm?
Copper:(a) Suppose you have a cube of copper metal that is 0.236 cm on a side with a mass of0.1206 g. If you know that each copper atom (radius = 128 pm) has a mass of 1.055 ×10–22 g (you will learn in Chapter 2 how to find the mass of one atom), how manyatoms are there in this cube? What fraction of the cube is filled with atoms? (Orconversely, how much of the lattice is empty space?) Why is there “empty” space in thelattice?(b) Now look at the smallest, repeating unit of the crystal lattice of copper.Knowing that an edge of this cube is 361.47 pm and the density of copper is 8.960g/cm3, calculate the number of copper atoms in this smallest, repeating unit
a) Water rises to a height of 20 mm in a capillary. If the radius of the capillary is made one third of itsprevious value then what is the new value of the capillary rise?b) The density of a pure liquid is 1.5 g/mL. If 4.3 mL of a liquid contains 60 drops, then calculate thenumber of molecules per drop of liquid (Molar mass of liquis: 80.4 g/mol, NA=6.02x1023).
Choices for the first one are solid, liquid, or gas the second and 3rd are nothing, it will melt, it will freeze, it will boil, it will condense, it will sublime, or it will deposit.
1. Why are liquids more dense than gases? and Why are liquids harder to compress than gases?
joules to warm 44.0 ML of water density equals 1.00 g/milliliters form 48.0°C to 100°C and vaporize it at 100°C.
