A cane is taken out from a refrigerator at `0^(@)"C"`. The atmospheric temperature is `25^(@)"C"`. If t1 is the time taken to heat from `0^(@)"C"` to `5^(@)"C"` and `t_(2)` is the time taken from `10^(@)"C"` to `15^(@)"C"`, then the wrong statements is

A

`t_(1)gtt_(2)`

B

`t_(1)ltt_(2)`

C

`t_(1)=t_(2)`

D

there is no relation

Text Solution

Verified by Experts

The correct Answer is:
B

According to Neton 's law of cooling `t_(1)` will be less than `t_(2)`
