5. In a hotel, food is stored in a freezer at -20 °C,
(1) What would be the temperature if it was raised by 5 °C?
(11) What would be the temperature if it was lowered by 0.5 °C every hour for 12 hours?
Answers
ANSWER:
1)-20+5=15°C
2) 0.5*12=6.0
SO, -20-6= (-26°C)
In a hotel, food is stored in a freezer at -20 °C,

(2) What would be the temperature if it was lowered by 0.5 °C every hour for 12 hours?
(1)
(2)
food is stored in a freezer at -20 °C
(1) temperature if it was raised by 5 °C
(2) the temperature if it was lowered by 0.5 °C every hour for 12 hours
- What would be the temperature if it was raised by 5 °C?
- What would be the temperature if it was lowered by 0.5 °C every hour for 12 hours?
Food is stored at -20°C
Situation of 1 part :-
It’s said that temperature is raised by 5°C [ ← increased i.e. we have taken as +5°C]
Temperature when raised
Situation of 2 part:-
Current temperature °C
Temperature lowered per hour °C [← lowered i.e. we have taken as -5°C]
Hence temperature lowered in 12 hour °C
Temperature after 12 hours
