A 20.0-L volume of methane gas is heated from 25°C to 70°C at constant pressure. What is the final volume of the gas?

2. The average length of time for students to
have their subjects controlled is 40 minutes. A
new controlling procedure using modern
computing machines is being tried. If a random
sample of 15 students has an average
controlling time of 25 minutes with a standard
deviation of 12.9 minutes under the new
system, test the hypothesis that the average
length of time to control student’s subjects is
less than 40 minutes. Use a level of
significance of 0.10 and assume the
population of controlling times to be normally
distributed.

A parallel-plate capacitor has an area of 100 mm2 and the plates are separated by 100 μm . If the capacitor contains paper between the plates, what is its capacitance
The average weight of 80 randomly
selected sacks of rice is 45.54 kilos with a
standard deviation of 17 kilos. Test the
hypothesis at a 0.01 level of significance that
the true mean weight is less than 49 kilos. 2. The average length of time for students to
