NEED HELP!!!!

When an experiment began, the temperature of a substance was −5°C . During the experiment, the temperature rose exponentially. The scientist will sketch a graph of the situation, where x represents the time after the experiment began, and y represents the temperature of the substance at that time.
The scientist will only sketch the graph in the quadrant or quadrants for which it makes sense to.

In which quadrant or quadrants will the scientist sketch the graph?



Quadrant I only
Quadrants I, II, III, and IV
Quadrants I and II only
Quadrants I and IV only


The graph represents the atmospheric pressure, in grams per square millimeter, as a function of altitude in miles above sea level.

Which statements accurately reflect this relationship?

Select each correct answer.



As the altitude decreases, the atmospheric pressure decreases.
The atmospheric pressure is 8 g/mm2 at sea level.
The atmospheric pressure gets close to 8 g/mm2 as the altitude continues to decrease.
As the altitude decreases, the atmospheric pressure approaches 0 g/mm2 .

Hello! Just took the test:

As the altitude approaches sea level, the atmospheric pressure increases

and

The atmospheric pressure is 14lb/in^2 at sea level.

Also

Quadrants l and lV only

From the graph attached, we can deduce the following relationships required to solve the questions posed :

A.)

The plot occupies both the lower and upper portion of the graph, which covers the third and fourth quadrant. Hence, the scientist will sketch the graph at the first and fourth quadrant.

B.)

From the graph, the atmospheric pressure decreases as the altitude (Distance from sea level) increases. Hence, the true statements are :

  • As the altitude decreases, the atmospheric pressure approaches 0 g/mm²
  • The atmospheric pressure is 8 g/mm2 at sea level.
