Question

2. State Newton's law of cooling. Draw graph between temperature (0) and time (1)
for a body cooling in air.
[2]​

Answer 1

Answer:

The constant 'k' depends upon the surface properties of the material being cooled.

This equation represents Newton's law of cooling. If k <0, lim t --> ∞, e-kt = 0

T= T2 , The graph drawn between the temperature of the body and time is known as cooling curve.
