Answer:
A_____PENCIL______ consists of a mixture of graphite powder (a form of carbon) and clay that is baked and hardened and encased in wood or paper. a. silverpoint b. pencil c. charcoal d. chalk e. paste
Explanation:
A pencil is a writing material, where the graphite is what gives the black color to the writing stroke.
Explanation:
a) Boyle's law states that pressure is inversely proportional to the volume of the gas at constant temperature.
(At constant temperature)
The equation given by this law is:
where,
are initial pressure and volume respectively.
are final pressure and volume respectively.
b) A graph of the relationship is attached as an image.
Hey there!
LEVELING FORCES WEATHERING AND EROSION ARE BOTH KNOWN AS LEVELING FORCES - WHICH MEANS THEY WEAR DOWN AND REMOVE ROCKS THAT ARE EXPOSED ON EARTH'S SURFACE.
WEATHERING IS THE BREAKUP OF ROCKS AT EARTH'S SURFACE DUE TO EXPOSURE TO THE ATMOSPHERE.
In particular, the two substances that do the most damage to rocks are:
<span>
OxygenWater</span>
The presence of just water and oxygen in the atmosphere is enough to break down all rocks given enough time.
EROSION IS THE REMOVAL AND TRANSPORTATION OF WEATHERED ROCK BY NATURAL AGENTS SUCH AS:
<span>
windglaciersriversrainwavescurrents</span>
WEATHERINGThere are many different processes that cause weathering, but all of them can be broken up into two main types:
<span>
Mechanical Weathering<span>
Chemical Weathering</span></span>
MECHANICAL WEATHERING
MECHANICAL WEATHERING (AKA PHYSICAL WEATHERING) OCCURS WHEN A ROCK BREAKS APART INTO SMALLER PIECES.
THIS IS A PHYSICAL CHANGE ONLY - THE PIECES ARE EXACTLY THE SAME AS THE WHOLE, JUST SMALLER
Hopes this helps u :D
Answer:
initial temperature=
Explanation:
Assuming that the given follows the ideal gas nature;
mole of gass will remain same at any emperature:
putting all the value we get:
initial temperature=
Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
