Question

the temperature of a hot metallic rod is 278 degree Celsius at 12 noon if it is made to cool off at the rate of 5 degree Celsius every minute then what will be the temperature at 12:15 p.m. and what will the temperature after 2 hrs​

Answer 1

Step-by-step explanation:

Temperature after 15 minutes i.e.(12:15pm)= 278-15×5=278-75= 203K

Also,

Temperature after 120 min(i.e.2 hrs)=278-120×5=278-600

But temperature of any particle cannot be less than 0K

Therefore the temperature of the rod is 0K
