You have two solid rectangular "prisms" made of pure elements. The face area of each prism 1 cm2 and each prism has the same mass (15 g). The length of prism A (metallic, grayish white in color) is 2.8 cm and for prism B (metallic, silvery gray in color) is 3.3 cm. The element in prism A has an atomic weight of 73 while prism B's element has an atomic weight of 48. Both samples are at the same temperature...

19. What can you conclude about one mole of two different gases at the same temperature and pressure? one mole of two different gases cannot have the same temperature one mole of two different gases cannot have the same pressure the gas with the most molar mass has the greatest average kinetic energy both gases have the same kinetic energy is the passage of gas through a small hole and __is the mixing of gas...

Soil acidity is measured by a quantity called pH. A scientist wants to estimate the difference in the average pH for two large fields using pH measurements from randomly selected core samples. If the scientist selects 20 core samples from field I and 15 core samples from field 2, independently of each other, find the approximate probability that the sample mean of the 40 pH measurements for field 1 will be larger than that for field 2 by at least...

Five samples of neon gas are described in the table below. Rank the samples in order of increasing average kinetic energy of the atoms in them. That is, select "1" next to the sample in which the neon atoms have the lowest average kinetic energy. Select "2" next to the sample in which the neon atoms have the next lowest average kinetic energy, and so on. sample average kinetic energy of atoms in sample amount pressure temperature -28 °C 1.2...

Two go-karts are racing. The total mass of each kart is the same, including the driver. One go-kart has a velocity twice as much as the other kart. If both karts have to slam on brakes to make a sudden stop, explain and compare the two karts’ kinetic energy and the work done by each kart to stop.
