What was done in the "heat transfer" lab after placing blocks of ice on different materials?

observing melting times to see which materials made good insulators

observing what happened when different materials got cold

recording the amount of water that melted from each piece of ice

recording how different materials responded to getting wet

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 =

now we have

here L = latent heat of fusion

also we know that

= 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

the answer would be   dignified - apex

ice to water 1 water to vapour 2 latent heat
