Which set of values represents standard pressure and standard temperature? (Table A)

• 1kPa and 273 K

• 1 atm and 101.3 kPa

• 101.3 atm and 273 C

• 101.3 kPa and 0 C

A rigid cylinder with a movable piston contains 50.0 liters of a gas at 30.0 C with a pressure of 1.00 atmosphere. What is the volume of the gas in the cylinder at STP? (Table A)

• 455 L

• 45.0 L

• 5.49 L

• 55.5 L

A 100 g sample of H2O(l) at 22.0 C absorbs 8,360 joules of heat. What will be the final temperature of the water? (Table B)

• 18.3 C

• 42 C

• 20 C

• 25.7 C

What is the total amount of heat required to vaporize 1.00 gram of H20(l) at 100 C and 1 atmosphere? (Table B)

• 334 J

• 373 J

• 2,260 J

• 4.18 J

Explain, in terms of heat of fusion and heat of vaporization, why the heat added during interval DE in the given graph is greater than the heat added during interval BC for the sample of water. (Table B)

• There is more heat added to DE than to BC

• According to Table B, heat of fusion requires 334 J/gC and heat of vaporization requires 2260 J/gC. Because vaporization requires more energy, interval DE has more heat added.

• Evaporation requires more energy than melting

• This is not true - both intervals have the same amount of energy

Based on the given data, show a numerical setup for calculating the change in the thermal energy of the water in the bottle from 7 am to 3 pm. (Table B)

• Q = (800g)(4.18 J/gC)(20.5C-12.5C)

• Q=(800g)(334J/g)(20.5-12.5)

• Q=(800g)(4.18J/gC)(20.5C)

• Q=(800g)(4.18J/gC)(12.5C)

Which quantity is equal to 50 kilojoules? (Table C)

• 0.05 J

• 500 J

• 5 x 10^4 J

• 5 x 10^3 J

The concentration of a solution can be expressed in (Table D)

• joules per kilogram

• milliliters
