Answer:
observing melting times to see which materials made good insulators
Explanation:
In heat transfer lab we need to determine that which material is a good conductor of thermal energy
so here we will find that thermal conductivity with the rate of thermal energy.
As we know that we put a ice cube on different material
so here the thermal energy will help to melt the ice
So here we can say that
rate of energy = [tex]\frac{dQ}{dt}[/tex]
now we have
[tex]\frac{dQ}{dt} = L\frac{dM}{dt}[/tex]
here L = latent heat of fusion
also we know that
[tex]\frac{dM}{dt} [/tex] = rate of mass melting
so if we measure that how much ice is melting with respect to time then we can find the rate of energy and hence we can find the thermal conductivity of the material
so correct answer will be
observing melting times to see which materials made good insulators
