A gas is heated from 263 K to 298 K, and the volume is increased from 24 L to 35 L. If the original pressure is 1 atm, what would the final pressure be? *
Answers
Since for closed system moles of the gas is always conserved
so as per idea gas equation we can say
so here we can say
so here we have
as we know that
now from above equation
on solving above equation we have
so here pressure will be 0.78 atm
Final answer:
Based on the combined form of the ideal gas law, the final pressure of the gas, given the changes in volume and temperature, would be approximately 0.725 atm.
Explanation:
The question concerns the change in conditions of a gas and asks you to determine the final pressure. This deals with the combined form of the ideal gas law, which states that the product of the initial pressure and volume, divided by the initial temperature, equals the product of the final pressure and volume, divided by the final temperature (P₁V₁/T₁ = P₂V₂/T₂).
Given that the initial pressure P₁ is 1 atm, initial volume V₁ is 24 L, initial temperature T₁ is 263 K, final volume V₂ is 35 L, and final temperature T₂ is 298 K, we can substitute these values into the equation to solve for the final pressure P₂.
Therefore, P₂ = P₁V₁T₂ / V₂T₁ = (1 atm × 24 L × 298 K) / (35 L × 263 K) ≈ 0.725 atm. So, the final pressure of the gas would be approximately 0.725 atm.

Answer:
When you rub your hands together, the entropy of the universe increases. This increase in entropy is a result of the second law of thermodynamics, which states that in any energy transfer or transformation, the total entropy of an isolated system will always increase over time.
In this case, when you rub your hands together, you are converting some of the ordered kinetic energy of your hand motion into thermal energy (heat) due to friction. This process increases the randomness and disorder of the particles involved, including the molecules in your skin and the surrounding air. As a result, the overall entropy of the system, which includes your hands, the air, and everything else involved, increases.
So, the act of rubbing your hands together leads to an increase in entropy in the universe, consistent with the second law of thermodynamics.

Answers
Correct answer choice is:
C. forefinger in the direction of the lines of force.
Explanation:
The direction of the force - and consequently the transfer of the wire - can be defined by applying Fleming’s left-hand rule.
The forefinger tends to the direction of the magnetic field. The middle finger points in the course of the current. The thumb supplies the direction of force or movement working on the conductor. Fleming's Left Hand Rule is applied in electronic engines which are utilized in coolers, appliances, printers, etc.

That's all you really know about them. They can be in ANY two
different directions; just not both in the same direction.
If they were both in the same direction, then the magnitude of
their vector sum would be the sum of their magnitudes, and
the direction of their vector sum would be the same direction
as both of them.
