Help Needed: Fire Safety Table with Low Numerical Values

[brewster]

Hi

I need help with a question in a Fire Safety course I'm studying for. The question reads :

Define the following terms and indicate the units in which they are normally expressed.

State how low numerical values for these properties would affect the ease with which solid materials can be ignited (set out your answer in the form of a table)

1) Density
2) Specific Heat
3) Thermal Conductivity

I've answered the first part but have no idea how to put together a table to answer the second part. My physics is poor. Any help would be appreciated.

Answer:1) Density – The amount of mass per unit volume of a material, usually expressed in kilograms per cubic meter (kg/m3).2) Specific Heat – The amount of heat needed to raise the temperature of a unit mass of a substance by 1 degree Celsius, usually expressed in joules per kilogram-degree Celsius (J/kg-°C).3) Thermal Conductivity – The rate at which heat moves through a material, usually expressed in watts per meter-kelvin(W/m-K).Table:Property | Low Numerical Value | Effect on IgnitionDensity | < kg/m3 | Lower density materials are easier to ignite as they contain less energy, allowing for more rapid heating.Specific Heat | < J/kg-°C | Lower specific heat materials are easier to ignite as they require less energy to raise the temperature of the material.Thermal Conductivity | < W/m-K | Lower thermal conductivity materials are easier to ignite as they require less energy to quickly raise the temperature of the material.
