Question

HELPPPP

Nitrogen is a gas at certain temperatures under normal conditions. These temperatures (t),
in degrees Celsius (°C) are represented by the inequality t > -196. Which best describes
the meaning of the inequality?
(2 points)
A.
Nitrogen is a gas only if the temperature is below -196(°C)
B.
Nitrogen is a gas only if the temperature is above -196(°C)
C.
Nitrogen is a gas only if the temperature is at or below -196(°C)
D.
Nitrogen is a gas only if the temperature is at or above - 196(°C)

Answer 1

B

Explanation:

The inequality says "t is greater than -196".

We can assume 't' means temperature.

With water, the gas state is warmer than the other states. (Steam is hotter than liquid water or water frozen solid.)

I took basic chemistry and I can tell you it is the same for other substances. - The gas state is the warmest.

So we can assume that Nitrogen is a gas at the warmer temperature.

Thus, we are looking for the statement that says Nitrogen is a gas when its temperature is greater than -196° Celsius.

B is the only one that matches.
