$40 - (5 \times 10) \\ 40 - 50 \\ = - 10$

Answer 2

Answer:

-10° c

Step-by-step explanation:

temperature decrease for every hour= 5° c

temperature decrease for 10 hours = 10×5=50°

temperature after 10 hours = 40° c - 50° c

= -10°c

the room temperature 10 hours after the Process begins will be -10°c
