Question

for water to be a liquid, its temperature must be within 50 kelvin of 323 kelvin. which equation can be used to determine the minimum and maximum temperatures between which water is a liquid? |323 - 50| = x |323 + 50| = x |x - 323| = 50 |x + 323| = 50

Explanation:

Step1: Understand absolute - value meaning

The distance between a variable temperature $x$ and 323 Kelvin should be 50 Kelvin. The formula for the distance between two numbers $a$ and $b$ is $|a - b|$. Here, $a=x$ and $b = 323$, and the distance is 50.

Step2: Write the absolute - value equation

The equation representing the distance between $x$ and 323 being 50 is $|x - 323|=50$.

Answer:

C. $|x - 323| = 50$
