Hello There! ^_^
Your question: What is the pressure of a fixed volume of hydrogen gas at 38.8°C if it has a pressure of 1.36 atm at 15.0°C..?
Your answer: P1/ T1= P2/ T2
Change C to Kelvin
273+ C= K
38.3+ 273= 311K
15.0+ 273= 288K
2.38/ 288= P2/ 311.3
740.894= 288 (P2)
P2= 2.57 atm.
Thus, you got you answer!
Hope this helps!
Answer:
Explanation:
If by speed ,you mean the rate at which they collide with each other then yes the answer would be
By decreasing the temperature
Since we already know thattemperature is the average kinetic energy of the molecules and increasing temperature will increase the motion of the solvent molecules and an decrease in temperature will decrease in the motion of solvent molecules
Snow is the result of moisture and low temperatures colliding; when they collide, they become tiny ice crystals. When ice crystals stick to one another, they become snowflakes. Snow is important to the water cycle because when they precipitate to the earth, they start to melt on surfaces warmer than themselves. The melted result becomes water, and when the water either seeps into the ground or flows into a source of water nearby, the water cycle's process repeats all over again.

Answer:
When an electric charge moves, heat is dissipated due to the drift velocity hence current is induced
Law of definite composition states that the elements in a given compound are always combined in the same proportion by mass. This law form the basis for the definition of a chemical compound.
