If a piece of metal is heated to temperature `theta` and the allowed to cool in a room which is at temperature `theta_0`, the graph between the temperature T of the metal and time t will be closet to

Text Solution

Verified by Experts

The correct Answer is:

By Newton's Law of cooling `T = T_(S) + (T_(H) - T_(S))e^(-kt)`
`T_(S) rarr` Temperature of surrounding
`T_(H) rarr` Temperature of body at t = 0
`K rarr` constant
`T rarr` Temperature of body at time t
