This exam is entirely multiple choice or true/false. A=T, B=F TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 1) The photosphere is about 100 times the diameter of the Earth, and large sunspots are larger than our whole planet. 1) 2) Granulation is the most obvious proof of solar convective energy transport. 2) 3) The solar corona is much cooler than the Sun's surface, hence we must wait for a total solar eclipse to glimpse it with the naked eye. 3)...

Convection is the transfer of ____ - ANSWER-heat through a material or substance Radiation is the ____ - ANSWER-projection of heat like the heat radiated by the sun or by an open flame T or F: Heat is always on the move, traveling only in one direction and always from hot to cold - ANSWER-false What are two methods of heat transfer? - ANSWER-conduction and convection What are two basic forms of refrigeration systems? - ANSWER-direct expansion and gravity flooded T or F: Conduction...

IFSTA Ch 5 Questions and Answers Graded A+ Question: What are the three primary means of heat transfer involved in fire behavior? Answer: The three primary means of heat transfer are conduction, convection, and radiation. Question: How does conduction contribute to the spread of fire within a structure? Answer: Conduction transfers heat through direct contact between materials, allowing fire to spread through walls, floors, and ceilings. Question: What role does convection play ...
