b) Thermal and electrical energy
c) Nuclear and electromagnetic energy
d) Power and work
Kinetic and potential energy
68. Which of the following is a type of energy not involved in the human body’s everyday processes?
A. mechanical energy
B. nuclear energy
C. thermal energy
D. chemical energy
nuclear energy
74. Feeling warmth from the sun on your skin is an example of:
a. Conduction
b. Convection
c. Radiation
d. Specific heat
Radiation
94. A pot of water is heating on the stove. Explain how all three heat transfer types (conduction, convection, radiation) might be involved.
Radiation: Heat from the stove burner is transferred as electromagnetic waves to the pot.
Conduction: Heat moves from the hot burner to the pot and then through the pot into the water by direct contact.
Convection: As the water heats, warmer water rises and cooler water sinks, creating convection currents that spread heat throughout the water.
