Answer:
atoms and molecules
Explanation:
as opposed to being continuous or just including particles). On the following page, the idea is stated as one of four concepts in Dalton's theory: “All matter is composed of tiny, indivisible particles called atoms”
Answer:
In order to improve visibility
Explanation:
Infrared telescopes are made using infrared cameras that contain infrared detectors which are solid-state and are maintained at very cold (cryogenic) temperatures
Infrared radiation is absorbed by water vapor which is present in the Earth's atmosphere, leading to the limitation of the use of infra red telescopes at high altitudes such as mountains, high flying planes or satellites
Answer:
Explanation:
Temperature is directly proportional to thermal energy of a body.
Thermal energy is one of the numerous forms of kinetic energy which dependent on the motions of the particles in a body.
When the temperature of a body increases, it possess more kinetic thermal energy. In this case, the molecules of the body gains more energy and begins to vibrate until they attain maximum kinetic energy.
The higher the temperature the more the kinetic energy.
Answer:
shielding of electrons
Explanation:
The addition of electrons shells results in the shielding of electrons away from the nucleus, most importantly the nuclear pull resulting from the charge.
- The nucleus pulls electrons to itself due to the net positive charge on it.
- As more electronic shell is added, the effect of the pull weakens outward.
- The inner shell experiences the nuclear pull more than the outer shell electrons.
The effect is responsible for a wide range of properties of elements.
Elastic limit, maximum stress or force per unit area within a solid material that can arise before the onset of permanent deformation. When stresses up to the elastic limit are removed, the material resumes its original size and shape. Stresses beyond the elastic limit cause a material to yield or flow.
