Need some help :) Thanks!
A sample of a glass occupies a volume of 525 ml at 625 mm Hg. At constant temp, what will be the new volume when the temp changes to the ff:
a.) 1.5 atm
b.) 455 mm Hg
Sure, I can help you with that!
To find the new volume when the temperature changes at constant pressure, we can use Boyle's Law, which states that the product of pressure and volume is constant, as long as the temperature and amount of gas remain constant.
Let's solve the problem step by step:
a) To find the new volume when the pressure changes to 1.5 atm:
1. Start by setting up the equation using Boyle's Law:
P1 * V1 = P2 * V2
2. Substitute the given values into the equation:
625 mmHg * 525 ml = 1.5 atm * V2
3. Convert the units to a consistent system. Let's convert mmHg to atm:
1 atm = 760 mmHg (approximately)
So, 625 mmHg is equivalent to 625/760 atm. Let's substitute the value:
(625/760 atm) * 525 ml = 1.5 atm * V2
4. Simplify the equation and solve for V2:
(625/760) * 525 ml = 1.5 atm * V2
V2 = [(625/760) * 525 ml] / 1.5 atm
Calculate the value to find the new volume V2.
b) To find the new volume when the pressure changes to 455 mmHg:
1. Again, start by setting up the equation using Boyle's Law:
P1 * V1 = P2 * V2
2. Substitute the given values into the equation:
625 mmHg * 525 ml = 455 mmHg * V2
3. Convert the units to a consistent system:
625 mmHg is equivalent to 625/760 atm, and 455 mmHg is equivalent to 455/760 atm.
(625/760 atm) * 525 ml = (455/760 atm) * V2
4. Simplify the equation and solve for V2:
(625/760) * 525 ml = (455/760) * V2
V2 = [(625/760) * 525 ml] / (455/760)
Calculate the value to find the new volume V2.
Remember to substitute the appropriate values into the equations and perform the necessary calculations.
I hope this explanation helps! Let me know if you have any further questions.
You need to proof your posts> Glass or gas? I suspect gas.
ff? who knows?
If temperature doesn't change, then volume won't change unless the pressure changes. .
