Answer:
must usExplanation:This question refers to the study of gases. To solve it, initially we e the following expression:
P × V = n × R × T
where P is the pressure (Pa), V is the volume (m³), n is the number of moles in the sample, R is the universal gas constant and T is the temperature (K). Transforming the units according to the equation, we have:
P = 2 × 10 ^ 5 Pa
V = 8/1000 = 0.008 m³
T = 27 + 273 = 300 K
Substituting in the equation, we have:
2 × 10 ^ 5 × 0.008 = n × 8.0 × 300
n = 0.667 moles
Finally, we use the following expression, which relates number of moles and sample mass:
m = M × n
where m is the mass (g) and M is the molar mass (g / mol). Thus, the mass of this gas is:
m = 28 × 0.667
m = 18.67 g
There can definitely become a huge decrease in self – esteem: This can lead to serious sadness and many other strong emotions. The person might start to feel that they are not pretty or might also start to compare themselves to other people and blame themselves for not being "perfect".
Internal anger– When a person experiences risky behavior it might be because of internal anger. If a person feels angered they might start to hide their anger beneath their emotions and appear as if everything's fine. If they continuously do this, they could become emotionally unstable.
