Question

10) To determine the gas constant R,
two students A and B perform an experiment
based on the ideal gas equation given as
Py = RT. Both use the
same gaseous sample having
v = 16.6 m3/mol and reported the
approximate value of R as 8.3J/(K A mol)
using the minimisation of sum squared
error. The data collected by both the
students are reported below. Choose the
correct option:
P(T)(Pa) 137 139 142 142 141
T(K) 274 276 278 280 282
Table 1: Data collected by student A.
P(T)(Pa) 137 141 142 148
145
T(K) 276 280 284 | 288
288 290

Answer 1

Answer:

Step-by-step explanation:

A is better than B

SSE of A is 14

Answer 2

Answer:

A has a better fit than BB. The R2 of A is 0.643 and R2 of B is 0.837.

b has fit better fit than A. The R2 of A is 0.643 and R2 of B is 0.837 since R2 of A is less than R2 of  B

B has a better fit than A, hence correct

Step-by-step explanation:

A has a better fit than BB. The R2 of A is 0.643 and R2 of B is 0.837.

b has fit better fit than A. The R2 of A is 0.643 and R2 of B is 0.837 since R2 of A is less than R2 of  B

B has a better fit than A, hence correct

since R2 do not match they do not have the same fit, hence incorrect

SSE of A is 6.7, not 14. hence it's also false.

SSE of A is 6.7, not 11.4 hence it's also false.

SSE of A and B are not 14 it's also false.
