Current Question (ID: 10800)

Question:

$\text{Mud houses are cooler in the summer and warmer in the winter because:}$

Options:

1. $\text{The mud is a superconductor of heat.}$
2. $\text{The mud is a good conductor of heat.}$
3. $\text{The mud is a bad conductor of heat.}$ (Correct)
4. $\text{None of the above.}$

Solution:

$\text{The correct answer is option 3: The mud is a bad conductor of heat.}$ $\text{Explanation:}$ $\text{Mud is a bad conductor of heat. So it prevents the flow of heat between surroundings and inside.}$ $\text{This thermal insulation property of mud makes mud houses cooler in summer and warmer in winter:}$ $\text{• In summer: The poor thermal conductivity of mud prevents the hot outdoor air from easily transferring heat to the interior, keeping the inside cooler.}$ $\text{• In winter: Similarly, the mud prevents the warm air inside from easily losing heat to the cold outdoor environment, keeping the interior warmer.}$ $\text{This is the same principle used in modern thermal insulation materials - materials with low thermal conductivity help maintain desired temperatures by reducing heat transfer.}$
