Solution

The correct option is B 512 times
For 10 rise in temperature, n =1
So rate =2n=21=2
When temperature is increased from 10C to 100C, change in temperature
=10010=90C
i.e.so, rate =29=512 times
alternate method with every 10 rise in temperature, rate becomes double.
So rr=2(1001010)=29=512 times
