When the temperature increases the pressure must also increase.
Answer:
Granitic gneiss is characterized by the separation of light- and dark-colored minerals into thin layers or bands.
Explanation:
Intense heat and pressure can also metamorphose granite into a banded rock known as "granite gneiss." This transformation is usually more of a structural change than a mineralogical transformation. Granite gneiss can also form through the metamorphism of sedimentary rocks.
Answer:
A. As the atoms move faster, the gas can change into a plasma.
Explanation:
When gas atoms get more and more energy, they move faster and faster. Therefore, when they collide, their speed is so high that an electron shedding occurs. This is plasma, ionized gas, that is, atoms that have some of their orbital electrons removed, and free electrons.
Answer:
Explanation:
frequency of tuning fork = 440 Hz
wave length λ = velocity of sound / frequency
= 343 / 440 m
= .7795 m
= 77.95 cm
λ = 77.95 cm
Let length of rod having fundamental wavelength of 77.95 cm be L
L = λ /2
L = 77.95 / 2
= 38.975 cm .
length of rod = 38.975 cm .
= 0. 39 m
