Answer:
Explanation:
Given that:
- area of concrete slab,
- thickness of the layer of air,
- temperature difference between the air and the concrete,
We have:
- thermal conductivity of air at S.T.P.,
<u>Now, according to Fourier's Law of conduction:</u>
putting the respective values:
Answer:
Explanation:
When water droplet condenses on the outer wall of glass of ice , it releases heat equal to mass x latent heat of condensation of water . This heat reaches the ice melting inside glass . Due to this heat , the melting process is accelerated .
Hence the process of melting gets accelerated when water droplet condenses on the outer wall of glass containing mixture of ice and water .
1 mile = 5,280 feet
5,280 feet = 63,360 inches
63,360 inches = 160,934.4 centimeters
