Answer:
Option A. It has stayed the same.
Explanation:
To answer the question given above, we assumed:
Initial volume (V₁) = V
Initial temperature (T₁) = T
Initial pressure (P₁) = P
From the question given above, the following data were:
Final volume (V₂) = 2V
Final temperature (T₂) = 2T
Final pressure (P₂) =?
The final pressure of the gas can be obtained as follow:
P₁V₁/T₁ = P₂V₂/T₂
PV/T = P₂ × 2V / 2T
Cross multiply
P₂ × 2V × T = PV × 2T
Divide both side by 2V × T
P₂ = PV × 2T / 2V × T
P₂ = P
Thus, the final pressure is the same as the initial pressure.
Option A gives the correct answer to the question.
An increase in thermal energy, changes the state of matter from solid to liquid to gas.
The structural formula of carbon is as shown below. Carbon is a nonmetallic and tetravalent compound that can accommodate 4 electrons to form a covalent bond. It has the capacity to establish bonds easily with other atoms and with other carbon atoms too, carbon is competent of establishing multiple stable covalent bonds with suitable multivalent atoms.
