1.
What are Mark and Emma mainly discussing?
The best way to store materials in a warehouse
Which material properties are needed for a thermal simulation
How to design a new product package
How to write a handbook about heat radiation
Explanation:
They discuss several material properties—thermal conductivity, specific heat capacity, density, emissivity, and thermal expansion coefficient—for thermal simulation.
2.
According to Mark, which property is the key property for thermal simulation?
Emissivity
Density
Thermal expansion coefficient
Thermal conductivity
Explanation:
Mark says, ‘Thermal conductivity is the key property.’
3.
What does Mark say density affects?
Size changes with temperature
Data reliability
Heat storage
Heat radiation
Explanation:
Mark answers, ‘Yes, density affects heat storage.’
4.
What sources does Mark recommend for finding reliable data?
Material databases and handbooks
Textbooks and magazines
Online forums and blogs
Laboratory experiments and interviews
Explanation:
Mark says, ‘Material databases and handbooks are good sources.’
5.
Why does Mark say the properties should be checked at different temperatures?
Because the properties can change with temperature
Because the simulation only works at low temperatures
Because density is always constant
Because the handbook contains only one set of values
Explanation:
Mark directly states that properties can change with temperature, so it makes sense to check values at different temperatures.
