Question

a certain freezing process requires that room temperature be lowered from 40c at the rate of 6c every hour.what will be the room temperature 10hour's after the process is begins? with explanation ​

Answer 1

Answer:

$Heya \: user \:$...............❤

Here,

Initial temperature = 40°C

Room temperature decrease at 6°C per hour.

Then,

Temperature charge in 1 hour = -6°C

& Temperature charge in 10 hours = (-6× 10)°C

= -60°C

Hence, room temperature after 10 hours = Initial temperature + temperature charge in 10 hours

= 40+ (-60) °C

= -20°C

Hope it’s helpful...... ☺

Answer 2

Answer:

Initial temperature = 40°C

Room temperature decrease at 6°C per hour.

Then,

Temperature charge in 1 hour = -6°C

& Temperature charge in 10 hours = (-6× 10)°C

= -60°C

Hence, room temperature after 10 hours = Initial temperature + temperature charge in 10 hours

= 40+ (-60) °C

= -20°C
