plzzzz tell me this answer..​

Answer 1

Answer:

I think 5 degree Celsius

Answer 2

Answer:

Step-by-step explanation:

Initial temperature = 30°C

∴Temperature changing in one hour = -5°C

  Temperature change in five hours  = -5°C × 5

                                                               = -25°C

∴Room temperature in five hours      = initial temp. + temp change in

                                                                                                   five hours

                                                               = 30°C + ( - 25°C )

                                                               = 5°C
