Question

Review Part A 4.0 g of oxygen gas, starting at 790° C, follow the process 1- 2 shown in (Figure 1 What is temperature T2 (in C)? Express your answer using two significant figures Figure 1 of 1 Pi Submit Request Answer Provide Feedback 0 0 V2

Answer 1

We have the ideal Gas Relation

PV=nRT

From these we can write

PiVi = nRT1 P2V2 = nRT2 or, PuVi _B V2 or, Ti = Tz therefore P2V2 T2 = T1 * PV from given graph note that P1 = 3P2 and Vi = 3V2 P2V2 or, T2 = 790(°C) x 3P2 x 3V2 or, Ty = 790, (°C) = 87.78 °C

Answer 2

You need to convert 790c to kelvin before doing the calculation in Answer #1's last step. The rest of Answer #1 is solid, though.
