Problem 37E

Which statement is true of the internal energy of a system and its surroundings during an energy exchange with a negative ΔEsys?

a. The internal energy of the system increases and the internal energy of the surroundings decreases.

b. The internal energy of both the system and the surroundings increases.

c. The internal energy of both the system and the surroundings decreases.

d. The internal energy of the system decreases and the internal energy of the surroundings increases.

Step-by-Step Solution:
Step 1 of 3

Solution: The spectrum of hydrogen atom has played a very important role in the development of atomic structure. It can be obtained by passing an electric discharge through the gas taken in the discharge tube under low pressure. The emitted light is analysed with the help of spectroscope. The spectrum consists of a large number of lines appearing in different regions of wavelengths. The line spectrum observed in case of hydrogen atom can be quantitatively explained using Bohr’s model. When an electron jumps from a lower orbit to a higher orbit, it absorbs energy. When the electron jumps from higher orbit...
