Answer:
bad thing.
Explanation:
most of Greenland is an icy island with the only main population on the west coast.
Although this would probably open up more land for use; the rising sea levels are a much bigger threat comparatively with the perks of warmer climate.
I believe the answer is C. (must be touching the object)
Someone please correct me if I am wrong.
Answer:
Final volume is 3.50L
Explanation:
It is possible to find volume of a gas using combined gas law:

<em>Where P is pressure, V is volume and T is temperature of 1: initial state and 2: final state</em>
If initial state of the gas is:
1.75L of a gas is at 700K and is under 250kPa of pressure
And final state is:
298K and 53.2kPa.
Replacing:

0.625L = 0.1785*V₂
<em>3.50L = V₂</em>
Thus, <em>final volume is 3.50L</em>
