Cooper is the substance that can't be decomposed by a chemical chAnge. So 4)
Answer:
Original volume=3L
Explanation:
Assuming the gas in the ballon is ideal and the temperature does not vary with height we have the gas law as
PV=nRT
Here RHS is constant in both the conditions which means
PV=constant
Given P1=1 atm V1=V P2=0.75atm V2=4L
P1V1=P2V2

V=3L
The initial volume of the gas is 3L
Answer: Sedimentary rocks
Explanation:
When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. ... When layers of eroded material pile up, it's called deposition. This can create new landforms.
Particles in a gas are always bumping against one another, it would be more accurate to compare it to a dance floor honestly
