a piece of iron has a temperature of 18 degrees celsius. A second identical piece of iron is twice as hot. What is the temperature of the second piece of iron? Please explain why.

Change 18C to Kelvins. Double it.

If the first piece of iron has a temperature of 18 degrees Celsius, and the second identical piece of iron is twice as hot, we need to determine the temperature of the second piece.

To find this, we can use the concept of proportionality. We know that the temperature of the second piece is twice as hot as the first piece.

Let's represent the temperature of the first piece as "T1" and the temperature of the second piece as "T2."

According to the given information, we have the following proportion:

(T2 / T1) = 2

We can solve this proportion by cross-multiplying:

T2 = 2 * T1

Substituting T1 with 18 degrees Celsius, we have:

T2 = 2 * 18
T2 = 36

Therefore, the temperature of the second piece of iron is 36 degrees Celsius. It is twice as hot as the first piece because we multiplied the temperature of the first piece by 2.

To determine the temperature of the second piece of iron, let's start by understanding the given information. We know that the temperature of the first piece of iron is 18 degrees Celsius.

It is stated that the second piece of iron is twice as hot as the first piece. This means the temperature of the second piece of iron is double the temperature of the first piece.

To find the temperature of the second piece, we can multiply the temperature of the first piece by 2.

18 degrees Celsius * 2 = 36 degrees Celsius

Therefore, the temperature of the second piece of iron is 36 degrees Celsius.

The reason why we multiply the temperature of the first piece by 2 is because it is stated that the second piece is twice as hot. In mathematics, multiplying a number by 2 is equivalent to doubling its value. So, by multiplying the initial temperature (18 degrees Celsius) by 2, we find the new temperature (36 degrees Celsius) of the second piece of iron.
