Question: Answer the following question given this paragraph: When using a microscope we do not see the entire extent of the sample. Depending on the eyepiece and objective lens we see a restricted region which we say is the field of view. The objective is then manipulated in two-dimensions above the sample to view other regions of the sample. Electronic scanning of either the objective or the sample is used in scanning microscopy. The image formed at each point during the scanning is combined using a computer to generate an image of a larger region of the sample at a selected magnification. When using a microscope, we rely on gathering light to form an image. Hence most specimens need to be illuminated, particularly at higher magnifications, when observing details that are so small that they reflect only small amounts of light. To make such objects easily visible, the intensity of light falling on them needs to be increased. Special illuminating systems called condensers are used for this purpose. The type of condenser that is suitable for an application depends on how the specimen is examined, whether by transmission, scattering or reflecting. See Figure 26.20 for an example of each. White light sources are common and lasers are often used. Laser light illumination tends to be quite intense and it is important to ensure that the light does not result in the degradation of the specimen. Q: When using a microscope we do not see the entire extent of the sample. depending on the eyepiece and objective lens we see a restricted region which we say is this? A:
OPTIONS:
- tunnel vision
- focal point
- peripheral view
- field of view
Answer: field of view

Q: Answer the following question given this paragraph: Today, these ideas about electrons are represented by the electron cloud model. The electron cloud is an area around the nucleus where electrons are likely to be. Figure below shows an electron cloud model for a helium atom. Q: What is the area around the nucleus of an atom where electrons are likely to be, called? A:

OPTIONS:
- electron wave
- electron membrane
- electron pocket
- electron cloud

A: electron cloud

input: OPTIONS:
- eardrum
- ear canal
- cochlea
- middle ear Now, answer this question: Answer the following question given this paragraph: The outer ear catches sound waves and funnels them to the middle ear. The middle ear amplifies the sound waves and passes them to the inner ear. The inner ear changes the sound waves to electrical signals. The signals travel to the brain, which interprets the sounds. Q: Which part of the ear amplifies the sound waves? A:
A:
output: middle ear

Question: Answer the following question given this paragraph: Under what conditions then, do gases behave least ideally? When a gas is put under high pressure, its molecules are forced closer together as the empty space between the particles is diminished. A decrease in the empty space means that the assumption that the volume of the particles themselves is negligible is less valid. When a gas is cooled, the decrease in kinetic energy of the particles causes them to slow down. If the particles are moving at slower speeds, the attractive forces between them are more prominent. Another way to view it is that continued cooling the gas will eventually turn it into a liquid and a liquid is certainly not an ideal gas anymore (see liquid nitrogen in the Figure below ). In summary, a real gas deviates most from an ideal gas at low temperatures and high pressures. Gases are most ideal at high temperature and low pressure. Q: Gases are most ideal at high temperature and what pressure? A:
OPTIONS:
- absolute
- high
- stable
- low
Answer:
low
