Answer:
Very Likely B.
Explanation:
Increasing temperature inside a closed container - keeping everything constant will make pressure increase. Because the energy being held by the molecular (the gas molecules) rises, the container may expand meaning the volume increases.
Answer:
244 .658 atm
Explanation:
The osmotic pressure is given by:
∏ = CRT
∏ = 10 × 0.0821 × 298
∏ = 244 .658 atm

An exothermic reaction is one where the products have lower energy than the reactants, so the reaction yields energy. The chemical compounds present in firework fuel release a lot of energy upon oxidation. Photosynthesis is endothermic, settling of silt is not a chemical reaction, it is a physical change. Finally, the bubble formation in soda is not exothermic; otherwise, the sodas would become very hot very fast.
Answer:
B. The air pressure would increase 2X
Explanation:
Pressure = density × acceleration due to gravity × height
p = ρ × g × h
Pressure is force per unit area
p = F/a
Density is mass per unit volume
Pressure is directly proportional to density hence, any change in the density of a body directly affects the change in pressure of the body and vice versa.
