The energy required to raise the temperature of the air in a room by 5.0°C is 336 kJ
U = 
m ΔT
U = Energy
= Specific heat
m = Mass
ΔT = Change in temperature
ρ = Density
V = Volume
ρ = 1000 g / m³ (Dry air )
= 1 J / g K
ΔT = 5 °C
V = 4 * 4 * 3
V = 48 m³
m = ρ V
m = 1000 * 48
m = 48000 g
U = 1 * 48000 * 7
U = 336000 J
U = 336 kJ
Therefore, the energy required to raise the temperature of the air in a room by 5.0°C is 336 kJ

I think I have already answer this question. Anyways please do let me know whether it is useful or not
Density of Earth: 5.514 g/cm³
Density of Jupiter: <span>1.326 g/cm³
1.326 g/cm³ / 5.514 g/cm³ </span>≈ <span>0,24
0,24 * 100 = 24%
Jupiter has 24% of earth's density.
(Density numbers are from internet, you may calculate with your own ones if u have )</span>
I believe your answer is off by a couple of decimal points. The answer is approximately 1.041 N
