Question

in a chemistery lab ,the room temperature is required to be lowered from 80 degree celsious at the rate of 5 degree celcius every hour.what will be the room temperature after 10 hours

Answer 1

Answer:

30 degree Celsius

Step-by-step explanation:

1 hour =5

10hour=5*10

so

• 80-50=30degree Celsius

Answer 2

Answer:

30 degree.

Step-by-step explanation:

Here.

Rate of temperature decreased in an hour = 5 degree

So, Rate of temperature decreased in 10 hour = 5 degree x 10 = 50 degree

Then,

Current temperature(80 degree) -  Rate of temperature decreased in 10 hour = Room temperature after 10 hours

= 80 - 50

=30 degree
