Number of breaths required to burn 2.5 kg mass of fat is 175000 breaths.
<h3>What mass mass of carbon dioxide is in one breath?</h3>
The mass of carbon dioxide in one breath is calculated as follows:
Volume of Carbon dioxide in one breath = 4% * 500
Volume of Carbon dioxide in one breath = 20 mL = 2 * 10⁻⁵ m³
Density of carbon dioxide = 2.0 kg/m³
Mass of carbon dioxide in one breath = 2 * 10⁻⁵ m³ * 2.0 kg/m³
Mass of carbon dioxide in one breath = 4 * 10⁻⁵ kg
Mass of carbon dioxide to be exhaled to burn 2.5 kg of fat = 2.8 kg * 2.5 = 7 kg of carbon dioxide.
Number of breaths required = 7 kg/4 * 10⁻⁵ kg
Number of breaths required = 175000 breaths
In conclusion, the mass of carbon dioxide in one breath determines the number of breaths required to burn 2.5 kg of fat.

I would sat the answer will be condensation if that's one of your choices
Answer:
46.73ºC
Explanation:
The sheets will change heat to achieve the thermal equilibrium, it means that they'll have the same final temperature (T). The heat (q) must be equal for both in magnitude, but with opposite directions.
The heat flows from the higher temperature for the lower, so it flows from the iron (Fe) to the gold (Au) sheet:
qAu = -qFe
The heat can be calculated by the equation:
q = m*cp*ΔT
Where m is the mass, cp is the specif heat capacity, and ΔT the temperature variation.
CpAu = 0.129 J/gºC
CpFe = 0.444 J/gºC
10.2*0.129*(T - 19.4) = -19.9*0.444*(T - 50.8)
1.3158*(T - 19.4) = -8.8356*(T - 50.8)
1.3158T - 25.52652 = -8.8356T + 448.84848
1.3158T + 8.8356T = 448.84848 + 25.52652
10.1514T = 474.375
T = 46.73ºC
