May someone help me on my homework? Thank you!

Problem 11.18 Part A An ideal gas at 20 °C consists of 2.2 × 1022 atoms. 5.8 J of thermal energy are removed from the gas Express your answer to two significant figures and include the appropriate units. figures and include the appropriate units T-Value C

Answer 1

As

U = N R T / (NA)

where NA = Avogadro's number.

Then

U = 89.04 J

After removing 5.8 J or energy,

U = 83.24 J

Using the formula we have to solve for T,

T = U (NA) / (N R)

T = 274.049 K or 0.899 degrees C [ANSWER]

*******************

As

e = 1 - Tc/Th

and Th = 360 C = 633.15 K

Then

Tc = 253.26 K or

Tc = -19.89 C [ANSWER]
