The Temperature of Magnesium: A Mathematical Inequality

In this article, we will explore the concept of temperature and its relationship with the melting point of magnesium. We will use mathematical inequalities to determine the number of minutes it takes for a sample of magnesium to reach its melting point.

The temperature of magnesium must be at least 650 degrees for the metal to melt. A sample of magnesium is currently 255 degrees. The temperature of the magnesium is increased by 10 degrees every minute. We need to find the number of minutes it takes for the magnesium to reach its melting point.

To solve this problem, we need to understand the concept of inequalities. An inequality is a statement that compares two expressions, indicating whether one is greater than, less than, or equal to the other. In this case, we want to find the number of minutes it takes for the magnesium to reach its melting point, which is 650 degrees.

Let's denote the number of minutes it takes for the magnesium to reach its melting point as x. Since the temperature of the magnesium is increased by 10 degrees every minute, we can represent the temperature of the magnesium after x minutes as 255 + 10x.

We want to find the value of x such that the temperature of the magnesium is greater than or equal to 650 degrees. This can be represented by the inequality:

255 + 10x ≥ 650

To simplify the inequality, we can subtract 255 from both sides:

10x ≥ 395

To isolate x, we can divide both sides of the inequality by 10:

x ≥ 39.5

Therefore, the number of minutes it takes for the magnesium to reach its melting point is at least 39.5 minutes.

Understanding the concept of inequalities is crucial in mathematics and real-life applications. In this case, we used an inequality to determine the number of minutes it takes for a sample of magnesium to reach its melting point. This knowledge can be applied to various fields, such as chemistry, physics, and engineering.

The concept of inequalities has numerous real-world applications. For example, in chemistry, inequalities can be used to determine the concentration of a solution. In physics, inequalities can be used to calculate the velocity of an object. In engineering, inequalities can be used to design and optimize systems.

In conclusion, the temperature of magnesium must be at least 650 degrees for the metal to melt. A sample of magnesium is currently 255 degrees. The temperature of the magnesium is increased by 10 degrees every minute. We used a mathematical inequality to determine the number of minutes it takes for the magnesium to reach its melting point. This knowledge can be applied to various fields and has numerous real-world applications.
