BSC 1011C Chapter Notes - Chapter 3: Evaporative Cooler, Kinetic Energy, Surface Tension

1. What is the difference between heat and temperature?
a. [Heat is the transfer of thermal energy and temperature is themeasurement of that energy transfer]
b. [Heat is the measurement of energy transfer and temperature isthe transfer of thermal energy]
c. [Heat and temperature mean the same thing - the transfer ofthermal energy]

2. What is "internal kinetic energy"?
a. [Moving energy that you cannot see with the naked eye (akamicroscopic)]
b. [Moving energy that you can see with the naked eye (akamacroscopic)]
c. [All forms of energy]

3. What is "internal potential energy"?
a. [Stored energy that you cannot see with the naked eye (akamicroscopic)]
b. [Stored energy that you can see with the naked eye (akamacroscopic)]
c. [All forms of energy]

4. What the difference is between "thermal energy" and"heat"?
a. [Thermal energy and heat mean the same thing. There is nodifference between them.]
b. [Heat results from thermal energy by either a change in phase ora difference in temperature.]
c. [Thermal energy results from heat either by a change in phase ora difference in temperature.]

5. In ionic bonding, one or more valence electrons aretransferred from one atom to another. When this transfer occurs,the receiving atom is now __________ charged.
a. [Positively charged]
b. [Negatively charged]
c. [Neutrally charged]

6. The solid state of ice is less dense than its liquidstate.
a. [True] b. [False]

7. Concrete has a higher heat capacity than water.
a. [True] b. [False]

8. Thermohaline circulation is driven by:
a. [Density] b. [Gravity] c. [Latitude] d. [Temperature] e.[Wind]

Which characteristic of water contributes to the relatively constant temperatures of the oceans?

A) Water ionizes only slightly.

B) It takes a small amount of heat energy to raise the temperature of water.

C) Water can contain large amounts of salt.

D) Water has the ability to ionize readily.

E) It takes a large amount of heat energy to raise the temperature of water.

Circle the word of phrase that correctly completes the sentece or answers the question. The property that allows water molecule to be attracted to each other is called (cohesion, adhesion). This propert is conferred by (covalent bonds, hydrogen gonds). This property is conferred by ( covalent bond, hydrogen bond). Ice is ( more dense, less dense) than liquid water. Water is polar molecule because of the unequal sharing of( electrons, protons) between the atoms in H2O. Adhesion of water to a surface is through the action of (covalent bond, ionic bonds, hydrogen bonds) between the water and the surace. Water is converted from liquid to vapor through the brakage of ( colvalent, hydrogen) bonds. Which (one) of these substance is not hydrophilic:( cellulose, oil, NaCl). Which of these will not dissolve in water, even though it is polar?(cellulose, oil, NaCl). Which of these is an electrolyte? (cellusose oil, NaCl). A buffer will contain a week acis , weak base, both).
