What is the change in energy of a gas at a pressure of 105 kPa, if 245 J of energy is added causing a change in volume from 25.3
Ahat [919]

Answer:

-1151.5 J

Explanation:

Given that:

The supplies energy = 245 L

The energy used in the expansion of gas = Pressure ×ΔV (change in volume)

At standard conditions;

Pressure = 105 × 10³ Pa

energy used in the expansion = 105 × 10³ Pa × (38.6 - 25.3)L

= 1396.5 J

Thus, the change in the energy of gas = 245 - 1396.5 J

= -1151.5 J

Hence, we can conclude that the gas has lost its own energy in the process of expansion.

1. A helium-filled balloon had a volume of 8.50 L on the ground at 20.0°C and a
maw [93]

Answer:

133.74 L

Explanation:

First we <u>convert the given pressures and temperatures into atm and K</u>, respectively:

  • 750.0 Torr ⇒ 750/760 = 0.9868 atm
  • 20°C ⇒ 20+273.16 = 293.16 K
  • 40°C ⇒ 40+273.16 = 313.16 K

Then we<u> use the PV=nRT formula to calculate the number of moles of helium in the balloon</u>, using<em> the data of when it was on the ground</em>:

  • 0.9868 atm * 8.50 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 293.16 K
  • n = 2.866 mol

Then, knowing the value of n, we <u>use PV=nRT once again, this time to calculate V</u> using <em>the data of when the balloon was high up:</em>

  • 0.550 atm * V = 2.866 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 313.16 K
  • V = 133.74 L

What is The most common form of matter in the universe
soldier1979 [14.2K]

Hello! My name is Zalgo and I am here to help you out today. The most common form of matter in the universe would be "Plasma".  Plasma is gas that is heated a lot so it turns into high energy (high energy would be said "Plasma").

I hope that this helps! :D

(By the way, do you think you could mark me as Brainliest? I'd greatly appreciate it! Thanks XP)
