Answer:
They are directly proportional
Explanation:
when the kelvin temperature increases, the average kinetic energy of particles increases and they move faster and vice versa.
Answer:
Middle: Self heating containers are really expensive but are useful because they are easy to use, portable, and can be recycled, unlike a camp stove which is not as easily moved.

They are important because they are the electrons that help the atom to bond with another atom. They are in the outer most shell. ☺️
A. weathering, transport, and deposition.
Explanation:
Water running downhill is an example of external force that shapes the landform on the earth surface.
Water is an important agent of denudation which plays a key role in scultpting the surface.
The action of running water downhill:
- Leads to weathering of the slopes by chemical and physical disintegration of the rock mass.
- The weathered materials are carried by the water and deposited at the foot of the hill.
- The process completes denudation.
- Denudation is the shaping of the earth surface through the action of wind,water, glacier and gravity.

Explanation:
Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:
pH=pKa+log[base]/[acid]
When the the concentrations of both buffer components (the weak acid and its conjugate base) are equal:
[base] = [acid]
So, pH=pKa+log1 = pKa
<u>pH is equal to pKa of weak acid of buffer system
.</u>
When buffer contains more of weak acid than conjugate base:
[base] < [acid]
log [base]/[acid] = Negative,
So,
<u>When more of acid component is present, the pH is more acidic. (It decreases)</u>
When buffer contains more of conjugate base than weak acid:
[base] > [acid]
log [base]/[acid] = Positive,
So,
<u>When more of acid component is present, the pH is more acidic. (It increases)</u>
