Answer:
a= 0.2m/s²
Explanation:
Fnet = ma
20 = 100a (divide both sides by 100)
a = 0.2m/s²
This question can be explained in a variety of ways, but the easiest can be that elements exist, and since each has a different atomic mass, all atoms are not identical in size and mass.
Exothermic type of reaction is taking place because this type of reaction generates heat energy.
<h3>What is exothermic reaction?</h3>
Exothermic reactions refer to those chemical reactions that produce heat energy and release that heat energy to the surrounding environment.
So we can conclude that exothermic type of reaction is taking place because this type of reaction generates heat energy.

Answer:
ΔP = -3556.36 Pa
Explanation:
Atmospheric pressure, P = 101300 Pa
Latent heat of boiling water, 
Boiling point at atmospheric pressure, T = 373.15 K
ΔT = 1 K
The change in volume as the water boils to vapor will be
Since the volume of vapor (
) is far greater than the volume of liquid (
)
Using the ideal gas equation:
R = 8.314 J/mol-K
ΔV = 0.0306 m³
Molecular weight of water, MW = 0.018 kg/mol
Using the Clausius - Clapeyron equation:
ΔP = -3556.36 Pa
But the pressure change is said to lower the boiling point of water, only a negative pressure change will lower the boiling point.
ΔP = 3556.36 Pa
