The atomic mass number of copper is A = 64. Assume that atoms in solid copper form a cubic crystal lattice. To envision this, imagine that you place atoms at the centers of tiny sugar cubes, then stack the little sugar cubes to form a big cube. If you dissolve the sugar, the atoms left behind are in a cubic crystal lattice. What is the smallest distance between two copper atoms?
The solar corona is a very hot atmosphere surrounding the visible surface of the sun. X-ray emissions from the corona show that its temperature is about . The gas pressure in the corona is about . Estimate the number density of particles in the solar corona.
a. Is there the highest temperature at which ice can exist? If so what is it? If not, why not?
b. Is there a lowest temperature at which water vapour can exist?
if so, what is it? If not, why not?
The U-shaped tube in FIGURE P18.57 has a total length of . It is open at one end, closed at the other, and is initially filled with air at pressure.
Mercury is poured slowly into the open end without letting any air escape, thus compressing the air. This is continued until the open side of the tube is completely filled with mercury. What is the length of the column of mercury?
A gas at temperature and atmospheric pressure fills a cylinder. The gas is transferred to a new cylinder with three times the volume, after which the pressure is half the original pressure. What is the new temperature of the gas?
