Explanation / Answer
1. What is the difference between heat and temperature?
a. Heat is the transfer of thermal energy and temperature is the measurement of that energy transfer.
BECAUSE: Heat is a form of energy whereas temperature is a scale to measure the energy.
2. What is "internal kinetic energy"?
a. Moving energy that you cannot see with the naked eye (aka microscopic)]
BECAUSE: Internal kinetic energy is the energy of the particles that form the system.
3.What is "internal potential energy"?
a. Stored energy that you cannot see with the naked eye (aka microscopic)
BECAUSE: It is the potential energy of the microscopic particle that forms the system
4. What the difference is between "thermal energy" and "heat"?
b. Heat results from thermal energy by either a change in phase or a difference in temperature.
BECAUSE: Thermal energy can be transferred from one object or system to another in the form of heat.
5. In ionic bonding, one or more valence electrons are transferred from one atom to another. When this transfer occurs, the receiving atom is now __________ charged.
b. Negatively charged
BECAUSE: The transferred electron is a negatively charged particle and add a negative charge to the earlier neutral atom.
6. The solid state of ice is less dense than its liquid state.
a. True
BECAUSE: In ice, the bonds between the water molecules are opened up due to hydrogen bonding and hence the molecules occupy a larger space decreasing the density.
7. Concrete has a higher heat capacity than water.
b. False
BECAUSE: It is water which has a higher heat capacity of 4,184 Joules.
8. Thermohaline circulation is driven by:
density
BECAUSE: Thermohaline circulation is the movement of seawater dependent on the changes in salt content and hence in density.
