How long does it take to raise the temperature of the air in a good-sized living room (3.00m×5.00m×8.00m) by 10.0∘C? Note that the specific heat of air is 1006 J/(kg⋅∘C) and the density of air is 1.20kg/m3.

Express your answer numerically in minutes, to three significant figures.

Answer : The time required is, 16.1 minutes.

Explanation :

First we have to calculate the amount of heat required to increase the temperature is:

where,

Q = amount of heat required = ?

m = mass

= density of air =

V = volume of air

C = specific heat of air =

= change in temperature =

Now put all the given values in above formula, we get:

Now we have to calculate the time required.

Formula used :

where,

t = time required = ?

Q = amount of heat required =

P = power = 1500 W

Now put all the given values in above formula, we get:

Thus, the time required is, 16.1 minutes.

the device is called “ rocket engine”

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
